Bosch electric screwdriver engine sparkles and smokes. Reversing switch of an electric screwdriver

Electric screwdriver sparkles inside and smokes

First of all, when an electric screwdriver smacked or smells burned, you need to turn it off. The reason for this is the operation of an electric screwdriver with a large overload. If you quickly turned off it is possible, it has not finally burned out and it can be restored. The electric screwdriver must be disassembled, remove the electric motor and carefully inspect it. In the case of a sharp smell of Gary, most likely an electric screwdriver has finally burned out. If the smell is felt a little slightly, the winding of the electric motor must be carefully examined. You need to inspect the engine collector. If the insulation of the winding has only darkened or a dot insulation violation, then the electric motor can still be saved. To do this, you can impregnate a point violation of insulation with nail polish. With darkening the winding, but there is no insulation violation, you can turn on an electric screwdriver for a short time without load. It is possible he will work further, but you need to handle it carefully. It is better to check the winding with a multimeter. I have more than once had to reanimate electric motors.![] 1

If your screwdriver smokes and a characteristic smell has appeared, then:

• Disconnect the tool. He should not work at this moment and should not be connected to the network.
• Make sure that the smoke did not come from the workpiece that you process using a screwdriver. For example, if you use the drill function and worked at high speed, then the wood could heat up and burned.
• If possible, disassemble the disabled screwdriver, getting to its electrical elements (to the engine, in particular).
• Carefully inspect everything regarding the winding. With its local burning, if it is barely noticeable and has a meager area, try to restore the varnished layer, soaking the problematic place with varnish. It’s easier if it is on the stature. But the combustion of varnish threatens with a breakdown.
• Gently remove dust and sawdust.
• If the breakdown is thoroughly eliminated and the smell of burning will not be turned on during the next turning on, then continue to use the screwdriver with a reduced load, lubricating it. The load falls the varnish. Low.voltage can let him work.
• In the case of other violations (anchor, brushes, bearings, wire or impossibility of diagnosis), appropriate repairs are necessary, which can be carried out if not qualified, then an experienced person. If the repair is impossible, select the screwdriver more powerful.

Well, what to do. we will repair, if you did not go to the service and came to us for advice. It is clear that this requires at least the basics of electrical engineering (terms and concepts)

Battery ships (screwdrivers) can generally rarely be blocked, compared with a network tool, 230 volts feeding from the network. This is due to both low voltage and lower power (reserves), but also among those and others, the main sources of smoke, I judge from their own experience, can be.

eaten brushes (you can see a lot of sparks in ventilation holes);

an interval closing of the stator winding (smoke also comes from ventilation, but the collector does not spark much);

malfunction of the inclusion button/switches (the button heats up, smells, cod is heard when turned on);

extremely unfavorable operating conditions. dirt, dust, foreign particles in the engine (smoke, noise, crowned fence clogged. This often happens during large.scale repair. stroke and t.P.)

Identify the source of smoke and smell and proceed to repair.

• The most just if the brushes burned. Just change them to new, better original. It happens that the brushes wear out to the fact that a copper contact wire, sprinkled into graphite, is starting to shorten the collector. sparks like from Bengal fire, the smell of burning and smoke. The new brushes will first spark a slightly more ordinary, until they develop the production of the radius equal to the diameter of the collector.
• If the winding is pierced, then little will help except rewinding, even varnish filling. It is better to change it right away. Yes, and the body movements for the possible resuscitation of the closed engine are not worth it, the new engine even on Makita and Bosch costs no more than 1000. And Interskovsky or Vyskovsky at 300-400.
• Very often heating, unpleasant odor and even smoke goes from the plastic button. It has contacts, and from frequent v. They, of course, spark and heat up, heat is transmitted and the plastic case that smells and smokes. My advice in this case is to change the entire button (to clean and bend contacts. what is the dead poultice)
• Will have to clean and wash. Just do not follow the advice of wise men who say that you can rinse the battery electric screwdriver by lowering the collector knot into the White Spirit and work for them for several minutes-this is nonsense. For cleaning, you will need to disassemble the shurik. Usually these are 6-8 bolts on one side of the case. Some bolts can be under the plugs, more carefully. Saving and remove the engine. Here it will be necessary and it will be necessary to rinse. Clean the furrows between the collector lamellas. Dry thoroughly! After drying, check it for the interval short circuit (short circuit) until it is connected to the switch (if you do it right in the shur, you can easily burn the working transistor of the switch. At least one wire from the engine must be soldered!). The engine is checked by a simple connection to the native battery of an electric screwdriver. If the engine works and does not smoke, then everything is in order with it. If it smokes or at least even smells stronger than usual. change the engine, it is already if not closed then. And the “fried” engine very quickly kills the battery, which is usually five times more expensive than the same engine.

An electric screwdriver smoke what to do

Greetings!People who have experience of repairing screws?

Mine had long been thrown off the speed on force gear at a slightly low load, and yesterday I generally twisted a couple of screws and smoked.

I dismantled it today, cleaned everything, removed the brush knot, washed everything inside. The brushes are still full. Connected purely the motor, and the brushes sincerely sparkle and begins to smoke.

Tell me, is it possible to fix it Why can it be so sparking so hard?

well, this is clear I would like to do with little blood.over, it is not a fact that the programs are in order. it has long been broken into a crunch.

That malfunctioning in the gearbox can be determined only after disassembly and defective.At the top it is possible even a reducer worker and simply the switching fixer has developed, so the speed flew out.The same crunch can be when the speed is not overpowered.But the replacement of the engine is small blood Since looking for a malfunction in it is such a matte, the sheepskin is not worth the shorter.If the Ketai engine for 12 volts costs around 500-600 Rublef.Well, let’s give a boshshsh, approximately a little more than the ruble.It was necessary to measure the cooperation on the collector when.And without this, the meaning was to disassemble?!In general, what should also be judged with the engine only after measurements.

the gearbox outwardly whole maybe because of the dirt he knocked him out.In short, you need to look for the engine I called a couple of firms. there is no shurik, but there are engines in general. We must go to select.

Well, in general, engines can be sold in small magazes.And so, of course, you need to pick up in fact.Since Makita can approach Bosch and T.D.

How to repair electric screwdriver/sparkles and stinks.

Such a case is possible, you buy a new engine, put it on an old gearbox, and the veil of the new engine smoked. There may be a problem in the gearbox, and the engine is difficult to crank the gears, and the load is huge, it is just like the drill will jam into the details that you are drilled, and you continue to press the button until the engine smokes.

The gearbox went and lubricated. it spins normally.

I tried to connect the engine on idle without a gearbox, smoke?

The engine is most likely to change the winding of the engine, I had a problem with the peorater, I decided to replace the rotor.

When the ventilation (from the back) is turned on from the grate, smoke with a characteristic smell begins to go

who recently gave a link to a large selection of motors for screwdrivers?

a year ago he asked about the same thing and also the crown as a result, he lives now, after a long downtime, he can again be planted, but then he twists the norms

P.S. revealed and did not find anything burned

Xs, when the gearbox died, tried to find a carcass or burned on Avito, did not come across and scored, lying around the computer. There are no inscriptions on the engine, but I looked at the pictures. my brushes stick out on my sides, and my 18 volts, your 14.

Some makits have a poor shutdown well and can be easily found by searching that Makita smokes. You can try to twist and look at the brushes and clean the collector.

Well, or drive in idle. It may cost

Smoke from electric screwdriver during operation

A considerable number of users came to face a situation where an electric screwdriver of Bosch, Dewalt, BlackDecker or not so eminent, but no less popular in brands was smoked. Various malfunctions can be the cause of the appearance of smoke. Depending on their localization and severity, the “resuscitation” of the device with small financial costs is possible, or more expensive repairs will be required.

If you own the necessary minimum of knowledge, time and tool, you can try to diagnose the breakdown yourself, however, it is better to contact the site of spare parts of the power tool. What to do if an electric screwdriver smokes:

• Disable power;
• disassemble the tool case to gain access to the main functional electric and mechanical components;
• clean the internal cavities and working parts;
• conduct a visual inspection of the wiring, winding of the anchor and stator, brushes, bearings;
• carry out repairs or replacement of defective nodes.

Types of faults

The situation in which the electric screwdriver smokes during operation is characteristic mainly for the network tool. in models with the battery, this is prevented by low voltage and low power. In any case, similar causes are capable of causing the appearance of smoke:

• worn brushes. this is an active sparking with a sign of this, observed through the ventilation holes;
• collector pollution;
• the closure of the stator winding turns. while the collector’s sparking can be moderate;
• malfunction of the button that causes its heating and burning the plastic parts;
• hit of small mechanical fractions (dust, dirt, chips).

What to do if an electric screwdriver smokes?

Pollution of the collector, anchor and stator can be eliminated by flushing in the white spite and mechanical cleaning of the paths between the lamellas. In other cases, if an electric screwdriver smoke, but it works, it will require replacing brushes, button or electric motor as a whole, since rewinding the winding at a price is comparable with the cost of a new node. The masters of the Successful Service Service Service Service Service Service will be able to perform these works quickly and inexpensively.

Electric screwdriver. Smoke from brushes

Sh/in Encor 14.4. After a long break in the work, smoke from the brush node periodically appears, during operation it disappears completely. how critical it is and how to deal with it? Once I saw a/video about the bulkhead and cleaning of the engine sh/c “. It also smoked there and then stopped and also incomprehensible.

You need to disassemble and clean you when storing something got there like oil

Alteration of charging devices and not only

There is nothing visually. And how can oil get there periodically?

Fubag160 wrote: And how can oil get there periodically?

The gearbox is flowing, with prolonged storage, the lubricant can be delayed and if stored upwards with a cartridge, everything will flow into the engine

Alteration of charging devices and not only

good evening ! The usual reason when the motor is smoking. the closure of the rotor turns. And he smokes at first stronger, because the batteries after charging give a large and then less and less. But to check the motor, it must be removed and twisted over the ammeter at idle, a good rotor will show 1.5.2a. The one that is worse is 2.5.3a.Well, if more than 3 at idle, you can safely change it- just do not forget to remove your native gear from it, new motors are usually sold without gear. Yes, when remove the motor- check whether there is a lubricant in bearings (bushings- there is an ordinary syringe or a vigor or motor oil- half a drop on each side) and whether there are no metallic sawdust between the rotor and magnets (it is often found.If a corner grinder operates nearby) it happens and the magnets come across split. if they dropped the shur. I usually sell boats with good brushes 300-400r and new ones are from 800 to 2 thousand today (these are large devalts of Bosha and Makita) well, this is in Nizhny Novgorod. If there is a need, I can and send. It is little likely that the lubricant from the gearbox will fall on the brushes. if they themselves did not pile up too much. usually everything is imposed on the manufacturer, not a drop of excess. in general, the moral of smoke is like that just like that, the good motor will not smoke. either the khan came to him. either something prevents him from spinning freely.

The main causes of the breakdown

Depending on how the breakdown manifests itself, its causes can be determined. There are 7 most common types of malfunctions, due to which the electric mechanism fails:

• Battery wear. the tool works weakly, requires more frequent recharging. Solution. buying a new battery and independent replacement.
• Damage to satellite or pin is a malfunction that can be eliminated by replacing components.
• If an electric screwdriver does not twist under load, this indicates the improper operation of the device.
• Damage to the shaft or bearings is another reason for poor work. During operation, the mechanism cracks and does not cope with the load.
• Wear of internal gears also violates the functioning of the device.
• Lack of lubrication in the gearbox. this happens if the tool is rarely used.
• He may not work due to burning the motor winding. In such a situation, a motor replacement requires.

Determine the cause not only with a visual examination of the device, it is necessary to perform diagnostics according to the following instructions:

• Disable the device from the network;
• Remove the cartridge;
• Remove the body part;
• remove gearboxes and a fixing plate;
• disassemble the gearbox to gain access to gears;
• inspect each complete set, evaluate the degree of wear or detect damage;
• replace broken details;
• set the springs with pliers to improve the device control;
• get to the bearings, check them, damaged. replace them;
• Check the condition of the motor, brushes and shaft.

Bearings and gears wear out with intensive operation quickly enough, so they require periodic replacement. The battery even in high.quality technology should also be periodically replaced.

How to understand that you need to change the brushes

Many change brushes only after they find strong sparkling of the tool, as well as the appearance of the smell of Gary. Even these signs do not stop many masters, and they continue to operate the tool until it stops turning on. When it is necessary to change coal brushes so as not to harm the device of the power tool. There are the following signs for this:

• Strong sparking. if signs of severe sparking appear, then it is necessary to disassemble the tool, and examine the consumables. Coming is the first sign that the consumables have to be replaced
• The appearance of the smell of Gary. if the smell of soot is heard during the tool, then it is recommended to disassemble the angular grinder and replace the graphite brushes
• With wear of the main part of more than 30%-40%. However, it is almost impossible to determine their initial length, unless you measure it before installing the elements
• When such signs appear as pulling and “growl” of the power tool

The devices are also replaced if they have uneven wear, and also do not correspond to the quality.

Preventive measures

In order not to accumulate graphite dust, you need to monitor the position of the brushes. Backlash should not be allowed, they should stand tight in grooves.

It is necessary to monitor the formation of an interval circuit in the anchor of the apparatus, in which the energy is heterogeneous to contacts, to some more in greater meaning, and to others in less. As a result of such a violation, sparks are formed.

The prevention of such a closure is carried out on a special device creating a magnetic field. Placing an anchor in the alternating field, the effect of rattling is obtained, due to the appearance of induced currents.

If the reason for the formation of sparking in a hand drill was an inter.seal circuit, then you need to apply a rewind or establish a new anchor.

For such reasons, there is a strong sparkling of any electrical screwdriver. Interskol, Bosh, Metabo or Makita. If the measures taken did not help to repair the device, it may be required to replace it.

Когда искрение щёток коллекторного двигателя — норма

The algorithm of the work of the collector electric motor is such that in the movement the brushes constantly come into contact with the collector, tearing and again closing the electric circuit. It is such a mechanism of functioning, directly related to the design features of the collector mechanisms, that is the inevitable cause of the appearance of sparks during its operation, even if the engine is absolutely good

However, it is important to understand that sparking in this case is minimal. Strong sparking, as a rule, suggests that the work of the collector engine is violated and in order to establish it, it is important to find out the cause of the malfunction

The brushes sparkle due to severe wear

Strong sparking of brushes can occur due to the fact that they have been very worn out. At the same time, the accompanying signs of wear, in addition to abundant sparks, will be the inability to develop the engine of full revolutions and access to full power, as well as a heavy start of the engine, which is not possible to carry out on the first attempt. Checking the version of the wear of the brushes is quite easy: the brushes should be pressed to the collector using a screwdriver. If the brushes are worn out, then with this pressing, the contact density is normalized and the engine operation will work out, however, sparks will appear again when the pressure is weakened. There is only one option for solving the problem in this case: replacing brushes with new. Some models of collector engines provide for the replacement of brushes only together with springs and holders.

Stator or rotor windings malfunction

With short circuits and inter.flood.circuits occurring in the windows of the stator or rotor, sparking will be uneven or even come from one of the brushes. About how to check the serviceability of the winding of the electric motor, is written in detail here. When diagnosing malfunctions of the windings, their rewinding may be required or, in difficult cases, a complete replacement of the rotor or stator.

Interpretation closing of anchor windings

In this case, both brushes of a faulty electric motor will sparkle, accompanying the “symptom” is a strong heating of the anchor winding associated with the uneven currents entering the contacts. As in the previous case, when diagnosing the problem in the winding, it is necessary either to rewind it or completely replace the faulty element.

Collector pollution

The brushes are a constantly wearing element of the collector engine, and in the process of their wear, the so.called graphite dust is formed, accumulating between the collector plates, which as a result leads to close and, as a result, the appearance of sparks

When working with a collector mechanism, it is important to monitor the position of the brushes: if they are displaced, the formation of graphite dust increases significantly. In addition to graphite dust, the cause of sparking can also be a soot formed on the collector due to overheating and creating excessive resistance when contacting the brushes with the collector

If the reason is the pollution of the collector, it must be cleaned with sandpaper, paying special attention to the space between the lamps

Why the drill is not turned on: the main reasons

First you need to investigate the contacts of the power cord with the tool. To do this, disassemble the case, find contacts and nickname them with a multimeter. If the problem is not this, then the switch is checked. Contacts can be oxidized, in this case they are cleaned with fine.grained sandpaper paper. One of the wires is also often ill with. You can determine this problem using a multimeter or resort to a simple diagnostic method. connecting a light bulb and a battery to this circuit.

Also possible reasons are:

• a malfunction of the connecting wires going from the switch to the engine brushes;
• damage to the brush node;
• more complex breakdown. damage to the windings of the anchor or stator;
• clogging the interval between the anchor and brushes lumpy dust.

Electric screwdriver sparkles inside and smokes

First of all, when an electric screwdriver smacked or smells burned, you need to turn it off. The reason for this is the operation of an electric screwdriver with a large overload. If you quickly turned off it is possible, it has not finally burned out and it can be restored. The electric screwdriver must be disassembled, remove the electric motor and carefully inspect it. In the case of a sharp smell of Gary, most likely an electric screwdriver has finally burned out. If the smell is felt a little slightly, the winding of the electric motor must be carefully examined. You need to inspect the engine collector. If the insulation of the winding has only darkened or a dot insulation violation, then the electric motor can still be saved. To do this, you can impregnate a point violation of insulation with nail polish. With darkening the winding, but there is no insulation violation, you can turn on an electric screwdriver for a short time without load. It is possible he will work further, but you need to handle it carefully. It is better to check the winding with a multimeter. I have more than once had to reanimate electric motors.![] 1

If your screwdriver smokes and a characteristic smell has appeared, then:

• Disconnect the tool. He should not work at this moment and should not be connected to the network.
• Make sure that the smoke did not come from the workpiece that you process using a screwdriver. For example, if you use the drill function and worked at high speed, then the wood could heat up and burned.
• If possible, disassemble the disabled screwdriver, getting to its electrical elements (to the engine, in particular).
• Carefully inspect everything regarding the winding. With its local burning, if it is barely noticeable and has a meager area, try to restore the varnished layer, soaking the problematic place with varnish. It’s easier if it is on the stature. But the combustion of varnish threatens with a breakdown.
• Gently remove dust and sawdust.
• If the breakdown is thoroughly eliminated and the smell of burning will not be turned on during the next turning on, then continue to use the screwdriver with a reduced load, lubricating it. The load falls the varnish. Low.voltage can let him work.
• In the case of other violations (anchor, brushes, bearings, wire or impossibility of diagnosis), appropriate repairs are necessary, which can be carried out if not qualified, then an experienced person. If the repair is impossible, select the screwdriver more powerful.

Well, what to do. we will repair, if you did not go to the service and came to us for advice. It is clear that this requires at least the basics of electrical engineering (terms and concepts)

Battery ships (screwdrivers) can generally rarely be blocked, compared with a network tool, 230 volts feeding from the network. This is due to both low voltage and lower power (reserves), but also among those and others, the main sources of smoke, I judge from their own experience, can be.

eaten brushes (you can see a lot of sparks in ventilation holes);

an interval closing of the stator winding (smoke also comes from ventilation, but the collector does not spark much);

malfunction of the inclusion button/switches (the button heats up, smells, cod is heard when turned on);

extremely unfavorable operating conditions. dirt, dust, foreign particles in the engine (smoke, noise, crowned fence clogged. This often happens during large.scale repair. stroke and t.P.)

Problems in the electric part

Signs of the device’s electrical malfunction are:

If the battery is discharged, it must be charged or replaced with charged from the kit. 2 batteries are included in many models of screwdrivers in the kit.

The reasons why the electric screwdriver does not be charged:

DOBA breakdown is revealed by measurement voltage at the exit from the device and comparison with passport data. Voltage is usually 10.8, 12, 14.4 or 18 volts. 18V batteries are most common. over, the value of the measured voltage in the case of a good car must be slightly higher than the passport. If the voltage is less or absent, then the charger must be repaired or changed. You can repair this device yourself, but you need to understand electronics.

If everything is in order with the memory, the battery is to blame. He will either not issue voltage, or issue less than the value. For example, the Fieldmann FDUZ 50001 battery has a nominal voltage of 18 V, and gives out 10-11 volts. In this case, a slow rotation of the cartridge will be observed. It should be noted that slow rotation is caused by a mechanical malfunction. But in this case, the work of an electric screwdriver will be accompanied by a characteristic noise.

Guess that this particular knot was also out of order by its heating. Why is the battery of electrical screwdriver to explain easily. either poor electrical contact between it and the engine, or poor electrical contact inside this node, between battery banks.

Sparks, smoke, crunch and smell of Gary: what can break in a drill or electric screwdriver

You can call as much as you like that the tool is not the same today, but the manufacturers are hacking, deliberately releasing “one.time” products, but let’s look in the eyes of the truth. Modern power tools are technically complex devices, and, like any equipment, they can eventually fail. Even the simplest drills and screwdrivers have 50. 100 parts, which move and rotate, rub and wear out, heat and burn out, experience significant loads and break. There can be a dozen reasons for breakdowns: improper operation, lack of proper care, defective components, unsuccessful design, excessive loads and simply randomness. In this article, we will consider typical malfunctions of drills and screwdrivers and find out their reasons.

Diagnosis of a drill in haste

To find out exactly why your drill broke or what is wrong with an electric screwdriver, you need to give the tool for diagnostics to the service center. But there are many direct and indirect features by which you can approximately find out in which knot there were problems.

So, we briefly figured out why the drill, electric screwdriver or peorator could work poorly. Then we will consider the typical causes of malfunctions in more detail and divide them into several categories: from easily eliminated problems to cases where the repair is inappropriate.

Not a breakdown at all

Some problems with drones and screwdrivers can not even be called malfunctions. Such annoying troubles include the wear of collector brushes. Graphite brushes are consumables (sometimes drills are sold immediately with a spare kit). They are more or less standardized, often interchangeable (running dimensions are suitable for the tool of different brands) and are literally a penny. Many drifts do not even need to open the body to replace brushes. This can be done without disassembling the power tool if the manufacturer for accessing inside has provided special windows covered with plugs. A powerful power tool, such as peorators, is even equipped with indicators that suggest that it is time to engage in the replacement of coal brushes.

If the indicator is absent, then the brushes themselves will give the green to know that they have worn out. The most striking (in the literal and figurative sense) sign of wear are powerful sparks that are visible through the slots of the case and ventilation holes. An indirect feature is the work of the tool with interruptions and jerks. Sparking occurs due to the fact that the brushes are not fully pressed to the collector. Sparking is accompanied by heat release. In addition to the smoke and smell of burning, which accompany the spark, the danger lurks in the fact that due to overheating, collector plates can be deformed and disappeared from the base of the collector. That is, without changing the brush in time, you can easily “rest” the engine anchor.

The “visual effects” described above are almost never in drifts and screwdrivers with browned engines. They generally have many advantages over tools with traditional engines (though the price is considerable). If something lightly sparkles inside a bronnial electric screwdriver under load, then this is the engine brake (and this is quite a normal phenomenon, not a malfunction).

Almost no breakdown

There are also problems that only look scary, but can be easily eliminated on their own with a screwdriver, sandpaper and a pair of strong words addressed to the manufacturer of the tool.

Serious troubles

Some malfunctions, unlike the above, can deliver a bunch of trouble and fly into a penny.

Excessive heating of the bearing of the drill (which can sometimes be recognized by the smoke and smell of burning plastic, as well as tight rotation of the cartridge and a loud “squeak”) indicates serious problems. The part.heated part can melt the plastic case of the tool. When melting, plastic will lose its shape, and a significant backlash will appear in detail. If the bearing is not lubricated or replaced, then over time it will collapse from overheating, or the anchor will jam. In the meantime, he does not fly to pieces, he will spoil your nerves with a loud howl and select part of the engine power.

If the shock drill has stopped taking concrete and brick, then this means that its shock mechanism has completely worn out. The electric drill is not arranged like a peorator. Instead of a “drunken” bearing or crooked-shaped mechanism, she has two rates with wavy surfaces that slide on each other, providing light blows with a drill on concrete. Over time, these “waves” naturally wear out, rates turn into flat washers, and a drill or electric screwdriver, who previously knew how to drill concrete, turn into an ordinary unstressed tool. It is possible to restore work in drilling mode only by repair with replacement of worn parts. Therefore, if you need to drill concrete not time from time to time, but regularly, it is better to immediately buy a normal peorator.

Almost hopeless cases

Serious breakdowns of engines and gearboxes are almost a “verdict”. We use the word “almost”, because repair with complete restoration of the functions of the tool is still possible. But sometimes (especially in the case of a browned power tool), the cost of repair is comparable to the price of a new device.

The reasons for the engine can be:

The gearboxes in drones break due to the low quality of metal, non-cumdy gears, lack of lubrication or (which happens much more often) due to excessive loads. If the slots on the shaft are “licked” or the teeth of the gear are broken off, then the entire node needs to be sorted out or changed entirely. It is better not to disassemble the planetary gearbox of the drill or electric screwdriver (except in cases where only the replacement of the lubricant is performed), because it has a lot of small details: gears, washers and seals.

Let’s summarize

There are many reasons why the power tool can spark, smoke, buzz and vibrate when working. Many of them are associated with improper operation and excessive loads. Therefore, you need to choose screwdrivers and drills correctly, based on specific tasks and working conditions. And if you just need a good tool, then you should pay attention to the products of Bosch, Dewalt, Makita, Metabo, AEG or other company with excellent reputation. The listed manufacturers have service centers in almost every region of the country, and you can buy spare parts for drills and screwdrivers of these brands almost freely.

Electric screwdriver sparkles inside and smokes

First of all, when an electric screwdriver smacked or smells burned, you need to turn it off. The reason for this is the operation of an electric screwdriver with a large overload. If you quickly turned off it is possible, it has not finally burned out and it can be restored. The electric screwdriver must be disassembled, remove the electric motor and carefully inspect it. In the case of a sharp smell of Gary, most likely an electric screwdriver has finally burned out. If the smell is felt a little slightly, the winding of the electric motor must be carefully examined. You need to inspect the engine collector. If the insulation of the winding has only darkened or a dot insulation violation, then the electric motor can still be saved. To do this, you can impregnate a point violation of insulation with nail polish. With darkening the winding, but there is no insulation violation, you can turn on an electric screwdriver for a short time without load. It is possible he will work further, but you need to handle it carefully. It is better to check the winding with a multimeter. I have more than once had to reanimate electric motors.![] 1

If your screwdriver smokes and a characteristic smell has appeared, then:

• Disconnect the tool. He should not work at this moment and should not be connected to the network.
• Make sure that the smoke did not come from the workpiece that you process using a screwdriver. For example, if you use the drill function and worked at high speed, then the wood could heat up and burned.
• If possible, disassemble the disabled screwdriver, getting to its electrical elements (to the engine, in particular).
• Carefully inspect everything regarding the winding. With its local burning, if it is barely noticeable and has a meager area, try to restore the varnished layer, soaking the problematic place with varnish. It’s easier if it is on the stature. But the combustion of varnish threatens with a breakdown.
• Gently remove dust and sawdust.
• If the breakdown is thoroughly eliminated and the smell of burning will not be turned on during the next turning on, then continue to use the screwdriver with a reduced load, lubricating it. The load falls the varnish. Low.voltage can let him work.
• In the case of other violations (anchor, brushes, bearings, wire or impossibility of diagnosis), appropriate repairs are necessary, which can be carried out if not qualified, then an experienced person. If the repair is impossible, select the screwdriver more powerful.

Well, what to do. we will repair, if you did not go to the service and came to us for advice. It is clear that this requires at least the basics of electrical engineering (terms and concepts)

Battery ships (screwdrivers) can generally rarely be blocked, compared with a network tool, 230 volts feeding from the network. This is due to both low voltage and lower power (reserves), but also among those and others, the main sources of smoke, I judge from their own experience, can be.

eaten brushes (you can see a lot of sparks in ventilation holes);

an interval closing of the stator winding (smoke also comes from ventilation, but the collector does not spark much);

malfunction of the inclusion button/switches (the button heats up, smells, cod is heard when turned on);

extremely unfavorable operating conditions. dirt, dust, foreign particles in the engine (smoke, noise, crowned fence clogged. This often happens during large.scale repair. stroke and t.P.)

Identify the source of smoke and smell and proceed to repair.

• The most just if the brushes burned. Just change them to new, better original. It happens that the brushes wear out to the fact that a copper contact wire, sprinkled into graphite, is starting to shorten the collector. sparks like from Bengal fire, the smell of burning and smoke. The new brushes will first spark a slightly more ordinary, until they develop the production of the radius equal to the diameter of the collector.
• If the winding is pierced, then little will help except rewinding, even varnish filling. It is better to change it right away. Yes, and the body movements for the possible resuscitation of the closed engine are not worth it, the new engine even on Makita and Bosch costs no more than 1000. And Interskovsky or Vyskovsky at 300-400.
• Very often heating, unpleasant odor and even smoke goes from the plastic button. It has contacts, and from frequent v. They, of course, spark and heat up, heat is transmitted and the plastic case that smells and smokes. My advice in this case is to change the entire button (to clean and bend contacts. what is the dead poultice)
• Will have to clean and wash. Just do not follow the advice of wise men who say that you can rinse the battery electric screwdriver by lowering the collector knot into the White Spirit and work for them for several minutes-this is nonsense. For cleaning, you will need to disassemble the shurik. Usually these are 6-8 bolts on one side of the case. Some bolts can be under the plugs, more carefully. Saving and remove the engine. Here it will be necessary and it will be necessary to rinse. Clean the furrows between the collector lamellas. Dry thoroughly! After drying, check it for the interval short circuit (short circuit) until it is connected to the switch (if you do it right in the shur, you can easily burn the working transistor of the switch. At least one wire from the engine must be soldered!). The engine is checked by a simple connection to the native battery of an electric screwdriver. If the engine works and does not smoke, then everything is in order with it. If it smokes or at least even smells stronger than usual. change the engine, it is already if not closed then. And the “fried” engine very quickly kills the battery, which is usually five times more expensive than the same engine.

After cleaning the body, grease the bearings and collect an electric screwdriver.

Purpose and properties of brushes for power tools

Brushes on an electric screwdriver of any brand, including Bosch (Bosch PRS 1200, PRS 1440, PRS 1800, Bosch GSR 14.4 in LI), Hitachi (Hitachi DS 12 DVF 3), Makita (Makita 6271 D, Makita DDF 454), Metabo, Pit and others, serve as a current conductor. They participate in the transmission of current to the rotor, thereby provide rotation. Therefore, the material for their manufacture should carry out electricity, be solid, so that under the influence of friction does not wear a lot.

Coal (graphite) brushes meet these requirements. This material in the event of the contacts of the electrical arc of the voltage is not welded to the metal. And when the motor is working, it occurs very often. Brushes on electric screwdriver should have resistance to temperature, mechanical and chemical influences, high thermal conductivity. Good brushes have a long service life, sparkle little.

You need to choose these details carefully, because they are produced in different sizes. To replace it is necessary to take products for a specific model of electric screwdriver and the same manufacturer. It must be borne in mind that with large loads and intensive work of the tool, the brushes will not last long.
