How to connect a circular saw through a starter. A brief description of the device

How to connect an electric motor 380V per 220V

It happens that a three.phase electric motor falls into the hands. It is from such engines that homemade circular saws, sandpaper and various kinds of grinders are made. In general, a good owner knows what you can do with him. But the trouble, a three.phase network in private houses is very rare, and it is not always possible to conduct it. But there are several ways to connect such a motor to the 220V network.

It should be understood that the engine power during such a connection, no matter how hard you try, will noticeably fall. So, the connection of the “triangle” uses only 70% of the engine power, and the “star” is even less. only 50%.

In this regard, it is advisable to have a more powerful engine.

Important! By connecting the engine, be extremely careful. Do everything slowly. When changing the circuit, turn off the power and discharge the capacitor with an electric lamp. Work at least together.

So, in any connection scheme, capacitors are used. In fact, they play the role of the third phase. Thanks to him, the phase to which the capacitor is connected, it is shifted exactly as much as necessary to simulate the third phase. Despite the fact that one container (working) is used to operate the engine, and for launching, another (starting) in parallel from the working. Although it is not always necessary.

For example, for a lawn mower with a knife in the form of a sharpened canvas, there will be enough an unit of 1 kW and condensers only workers, unnecessarily of containers for launching. This is due to the fact that the engine is idling when starting and there is enough energy to spin the shaft.

If you take a circular saw, hood or other device that gives the initial load on the shaft, then here you can not do without additional cans of capacitors for launch. Someone can say: “Why not connect the maximum container so that there is little?»But not everything is so simple. With this connection, the motor will overheat and may fail. Do not risk equipment.

Important! Whatever capacitance, their operating voltage should be at least 400V, otherwise they will not work for a long time and may explode.

First, consider how the three.phase engine is connected to the 380V network.

Three.phase engines are both with three conclusions. for connecting only to the “star”, and with six connections, with the possibility of choosing a scheme. a star or triangle. The classic scheme can be seen in the figure. Here in the drawing on the left shows a star connection. In the photo on the right, it is shown how it looks like a real Brne Motor.

It can be seen that for this it is necessary to install special jumpers on the desired conclusions. These jumpers come with the engine. In the case when there are only 3 conclusions, the connection to the star has already been made inside the motor body. In this case, it is simply impossible to change the connection diagram of the windings.

Some say that they did this so that the workers did not stole the units home for their needs. Be that as it may, such engine options can be successfully used for garage purposes, but their power will be noticeably lower than connected by a triangle.

Operating principle

During the launch of the collector type electric motor, a significant short.term increase in consumption current occurs, which causes the premature failure of the power tool and the delivery of it for repair. Wear of the electrical parts (current exceeding 7 times) and mechanical (sharp launch). For the organization of “soft” starting, you should use smooth starting devices (hereinafter referred to as UPP). These devices must meet the basic requirements:

• A smooth increase in load.
• The ability to start the engine at certain time intervals.
• Providing protection against linear jumps U, phase loss (for a 3-phase electric motor) and various interference of the electrical component.
• Significantly increasing life.

The most widespread is the Simistor SCP, the principle of action of which is smooth control U by adjusting the angle of opening the transition of the systemist. Simistor needs to be connected directly to the engine windings and this allows you to reduce the starting current from 2 to 5 times (depending on the simistor and the control circuit). To the main disadvantages of the Simistor SCP are the following:

• Complex schemes.
• Overheating of windings with prolonged launch.
• Problems with the launch of the engine (leads to a significant heating of stator windings).

The schemes are complicated when using powerful engines, however, with low loads and idle, it is possible to use simple schemes.

SCP with regulators without feedback (1 or 3 phases each) became widespread. In models of this type, it becomes possible to pre.set the launch time and the size of U before starting the engine. However, in this case, it is impossible to adjust the value of the rotational moment during the load. A special device is used with this model to reduce starting current, protection from loss and phase skew, as well as from overload. Factory models have the function of tracking the state of the electric motor.

The simplest schemes of single.phase regulation are executed on one simistor and are used for a tool with a power of up to 12 kW. There are more complex circuits that allow adjusting the engine power parameters with a capacity of up to 260 kW. When choosing a factory production SCP, it is necessary to take into account the following parameters: power, possible modes of operation, equality are acceptable currents and the number of launches in a certain period of time.

Use in corner grinding

During the launch of the angular grinding machine (angular grinder), high dynamic loads appear on the details of the tool.

Dear models are equipped with UPP, but not ordinary varieties, for example, an angular grinder of Interskol. An inertial jerk is able to tear out a corner grinder from the hands, while a threat occurs to life and health. In addition, when starting the instrument electric motor, the current is overloaded and, as a result of this, the wear of the brushes and significant heating of the stator windings, the gearbox wear out and the destruction of the cutting disk, which can crack at any time and cause harm to health, and maybe even life. The tool needs to be secured and for this you should make an angular grinding grinder with a speed of revolutions and smooth starting with your own hands.

How to make a smooth launch of power tools from a conventional outlet.

An ordinary outlet, if you finalize it a little, can extend your life to any instrument. corner grinder, circular saw, trimmer, etc.P.

All that is needed for this is a small box of smooth start, for example, a brand such as Krrqd12a.

It is well known that not every tool is equipped with similar schemes of smooth start. They mainly go in expensive models of famous brands Bosch, Hilti, Dewalt. over, both in the network line and in the battery.

The power tool without such a device has a bunch of disadvantages:

When working with a end saw having a PP, the disk will not be lost from the prepared cutting point. What is important for unprofessional joiners.

If you still do not have electricity at the cottage or house at the initial stage of construction and you use the generator, then sooner or later you will understand that without BPP (smooth starting block) with sharp initial currents, the generator will not last long. Therefore, such a thing is able to save not only the tool, but also emergency power sources.

You can certainly independently integrate the BPP into the inside of the same corner grinding or end, however, to disassemble the equipment and poke around in the insides, not everyone is hunting.

Plus everything else, opening a new building entails a loss of warranty. Therefore, the best use for the KRRQD12A unit. This is an external connection.

Just keep in mind, it is suitable for collector engines. For asynchronous you need a frequency with other principles of regulation.

This box is designed for current 12 amperes.

What is characteristic, their dimensions are the same, and the difference in price is a couple of dozen.

It would seem better to take it, but for a standard outlet in 16a, the first option is more profitable. There will be no desire to connect a more powerful load and thereby plow all the contacts.

Masters of self-made, of course, collect such schemes with their own hands, based on Tiristors VTA 12-600 or others, capacitors, dinistor and a couple of small resistors. Examples of schemes on the Internet can be found many.

But the ordinary user of the tool is much easier to buy all this in a ready.made compact case. You can order a similar block by link from here.

By the way, be careful, there are similar devices, but with three wiring. For example XS-12/D3.

Or other models look like krrqd.

But they are collected on a slightly different principle and they need to be installed after the start button, in the tool itself. The voltage to them should be supplied only at the time of the trigger button of the corner grinder and immediately disappear after releasing it.

The phase is made to contact “A”, zero on “C”. Further, the phase goes to the engine with the output wire of control (this is just the third wiring).

This is not in the two.wire block, since it is connected to the rupture of the circuit, and the voltage (potential difference) is applied to it only at the time of start.up and operation of the tool.

Another moment. The so.called electric brake or brake winding on ends. He may not work with a 3 wired external SPP, but with a 2-wired model will be.

The most important requirement for such a socket. This is her mobility. Therefore, you will need a carrying.

With it, it will be possible to smoothly start the tool anywhere. In the garage, in the country, during the construction of your house in different areas of construction site.

First of all, the carrier needs to be disassembled.

The main food wires in it can be either soldered or connected on screw clamps.

Depending on this, your additional outlet will also be connected. This should be an additional socket near the carrying, in order to be able to simultaneously connect the tool in different modes.

By the way, if you mistakenly turn on the corner grinder or circular, having a factory built.in smooth start in a socket, also equipped with such UPP, then everything will work surprisingly. The only moment. It will turn out to be a delay in starting a saw or revolution for a couple of seconds, which is not very convenient in work and without a habit can puzzle.

Homemade options

There are many schemes for the modernization of power tools using SCP. Among all varieties, devices on Simistors are widely used. Simistor is a semiconductor element that allows you to smoothly adjust the power parameters. There are simple and complex schemes that differ among themselves options for execution, as well as the supported power, connected power tools. The constructive design is internal, allowing you to integrate inside the body, and external, made in the form of a separate module, which acts as a speed limiter and starting current during direct starting angular grind.

The simplest scheme

UPP with the regulation of revolutions on the thyristor KU 202 has been widely used due to a very simple execution scheme (Scheme 1). Its connection does not require special skills. Radio elements for him to get it very simple. This model of the regulator is made of a diode bridge, a variable resistor (acts as a regulator U) and the tiristor setup circuit (feed U to a 6.3.volt number control exit) of a domestic manufacturer.

Scheme 1. The electrical circuit of the internal unit with speed adjustment and a smooth start (electrical circuit circuit)

Due to the size and number of parts, the regulator of this type can be built into the power tool case. In addition, the handle of a variable resistor should be removed and the revolution regulator itself can be finalized by integrating the button in front of the diode bridge.

The basic principle of operation is to adjust the revolutions of the instrument electric motor due to restriction of power in manual mode. This circuit allows the use of power tools with a capacity of up to 1.5 kW. To increase this indicator, it is necessary to replace the thyristor with a more powerful one (information about this can be found on the Internet or a directory). In addition, it is necessary to take into account the fact that the thyristor control scheme will differ from the original. KU 202 is an excellent thyristor, but its significant drawback is to set it up (a selection of parts for the control scheme). To make a smooth start in automatic mode, scheme 2 (SCP on the microcircuit) is used).

Smooth launch on the microcircuit

The best option for the manufacture of SCP is the SCP scheme on one simistor and microcircuit, which controls the smooth opening of the transition P-N type. The device from the 220 V network is powered and it is easy to assemble it yourself. A very simple and universal scheme of smooth starting the electric motor also allows you to adjust the speed (Scheme 2). Simistor can be replaced with similar or with characteristics exceeding the initial ones, according to the reference book of the semiconductor.type radio elements.

Scheme 2. Scheme of smooth launch of power tools

The device is implemented on the basis of the KR118PM1 chip and the Simistor. Thanks to the universality of the device, it can be used for any tool. It does not require tuning and is installed in the rupture of the power cable.

When starting the electric motor, the UD on KR118PM1 and the smooth growth of the capacitor C2 occur. The thyristor opens gradually with a delay depending on the capacity of the control capacitor C2. With a capacity of C2 = 47 μF, a delay occurs when it is launched about 2 seconds. It depends directly in proportion to the capacitor capacity (with a larger capacity, the launch time increases). When disconnected, the angular grinder capacitor C2 is discharged using the resistor R2, the resistance of which is 68 K, and the discharge time is about 4 seconds.

To regulate revolutions, you need to replace R1 with a variable resistor. When the parameter of the variable resistor changes, the power of the electric motor occurs. R2 changes the value of the current flowing through the input of the systemist. The simistor needs cooling and, therefore, a fan can be built into the module case.

The main function of capacitors C1 and C3 is the protection and management of the microcircuit. The Simistor should be selected, guided by the following characteristics: Direct U should be 400.500 V and direct current should be at least 25 A. With such values ​​of radio elements, it is possible to connect a tool with a capacity of 2 kW to 5 kW to the UPP.

Thus, to launch electric motors of various tools, it is necessary to use the UPP of the factory manufacturing or homemade. SCP are used to increase the life of the tool. When the engine is launched, there is a sharp increase in the consumption current by 7 times. Because of this, it is possible to burn stator windings and wear of the mechanical part. SCP allow significantly reducing the starting current. In the manufacture of SCP, you need to comply with the safety rules when working with electricity.

Photo, with numbers. I’ll tell you that you are preventing you from living.

In the sense of when the disk in the cut is inserted cannot unwind? Or just accelerates for a long time?

I have a 2kW Rebir and a 200mm disc, without smooth, when turning on, I need to hold tight.

If the error can be fixed, then you have not been mistaken yet.

Is it worth it to throw a smooth start on the circular, not a corner grinder/pshm.

Probably, you need a lot of short cuts. In this case, it can enrage. I don’t have it on Fiolent.

Connection of a smooth launch for power tools and checking the block for serviceability

Dear forum users ! All good day of day!The simplest explanation of how to connect and check the three.wire block.

2 kW (corner grinder, disk saw) for a smooth start is enough block for 12 A. For example, ZLB Kr.010 12 (12/250 V), 20 (20/ 125V). Maybe a block at all without marking, such as I got.The connection diagram of everyone has one.

The colors of the wires in different companies are completely different. BUT ! Conclusion “A”. always on the left side, and then accordingly goes “B”, and then “C”.For ZLB Kr.010 when calling the tester “a-s” 830 kOhm, “s” 127 kOhm. The remaining combinations do not call for a serviceable block.For my “unknown” regulator “a-s” 800 kom. and back “s-a” 690 to Ohms. The rest of the combinations do not call the same.Here is a scheme for checking the block through a light bulb (imitates email.motor) regardless of the position of the fork simulating a double switch.

Here. it is smoothly ignited and does not depend on how the plug in the socket is Suna (t.E wherever the phase is).

You can apply a two.wire regulator by 12 A or 20 A (it is not always inserted in the dimensions in more than 12A in place) when working and not with a dual, but a simple single switch (an old corner grinder Lepse 230). The two.wire on 20A can be installed directly in the extension cord for the power tool, provided that one unit is launched, and not a few, but, possibly or as they say now: Highly Likely, will burn out.

One.way tester calls for resistance, but no back. You should not pay attention to the color of the findings of a two.wire block. It is usually placed after a circuit breaker in a wire break (t.e. consistently to the motor).You can add a sorosel to one side to the motor or to it on two sides to reduce the flills during operation and the capacitor parallel to the entrance by 450V (I did not look at the capacity. I had in a corner grinder).

Rasiners on the video, on this subject, will rub your brains for 30 minutes and PR, hanging out wires-tuu-forth. But in the end. you will not understand anything. wooden, everything depends on greed.OK it’s all over Now! All health and good luck!

Launch of the electric motor through PM

As you know, an electromagnetic starter is an electrical switching device that is used to launch, protect and stop electric motors operating according to an asynchronous scheme.

The main working element of any starter is an electromagnetic contactor for alternating current networks.

It is the parameters of the contactor that determine the characteristics of the starter, such as the rated current and voltage, switching wear resistance and ability.

In addition to the contactor, the magnetic starter can be equipped with protection devices and a button station.

Connection of a magnetic starter to a three.phase network

As follows from the connection scheme. Three.phase voltage should be applied to the terminals F1, F2, F3. In order for the electric motor to begin to work, it is necessary to work a magnetic starter (PM) and its contacts PM1, PM2, PM3 closed its contacts. In order for the starter to work, the voltage supply is required, the value of which depends on the power of the coil.

The coil of the magnetic starter receives voltage from F1. But before that, it passes through the closed contact of thermal protection of the electric motor TP1. After passing through the starter coil, the current passes to the Start button, as well as to the blocking contact of the PM4 magnetic starter.

Next, the voltage goes to the closed button, after which there is a short circuit at zero.

To start the electric motor, you should press the start button. Next, the coil of the magnetic starter is closed. As a result, there will be a closure of contacts PM1, PM2, PM3. In addition, the PM4 contact will be closed.

It will make it possible to operate the electric motor after releasing the Start button. This phenomenon is called self.plate. To stop the electric motor, you need to break the circuit of the coil of the PM. To do this, press the stop button (KN2).

In this case, all contacts of PM1, PM2, PM3, PM4 will open up. The electric motor will stop to subsequent launches.

To provide protection against overloads, this circuit contains a thermal relay (TP). The electric motor during overloads is heated greatly, as a result of high current. As a result, its breakdown may occur. This protective device works when the current is increased on the phases, its contacts are opened. As a result, the operation of the button is simulated.

Turning circuit in reversal mode

The above connection scheme is suitable for electric motors operating in constant mode (circular, pumps, etc.). But for the units that should change the direction of rotation of the motor, you need a slightly different connection of the starter.

These are crane beams, winches, gate openers, etc. As can be seen from the scheme in the image, to connect such devices you need two identical starters. In addition, a three.button diagram is needed. That is, there should be two launch buttons and one stop.

Sometimes in such schemes it is also possible to use a two-button circuit, but only in cases of very short-term intervals (3-10 s). In this case, both buttons are normally open, but self.plate is not used. As a result, the unit is activated only while pressing the button.

When it is released, the device does not work. Otherwise the above scheme is similar to the above.

Connection PM to a single.phase network

Through a magnetic starter, you can also connect an electric motor designed for a single.phase network. First you need to decide on the type of starter. They are classified according to the working current.

Types of starters are marked with numbers from 1 to 7. The larger the number, the more current the device is calculated. In addition, to work on a single.phase network, the starter coil should be designed for a voltage of 220 V.

According to the scheme shown in the figure, it is necessary to introduce power off.related contacts. The electric motor must be connected to the release of the power contacts of the starter himself. Nutritions of the Stop and Stop buttons must be taken from the inputs of the starter’s power contacts.

For example, the phase should be connected to the button of the locking contact stop. Next, it should be connected to the starting button of a normally open contact. And already from the contact button start to contact the coil of the starter himself. Zero should be connected to the second contact of the starter coil.

To fix the starter’s position on, it is necessary to shunt the unit with the contactor of the start.up button start of the normally closed contact.

As you can see, the connection of this element in both a three.phase and a single.phase network is not a very difficult task. But still, in order to implement it, it is necessary to study the theoretical base and prepare. As a result, you can carry out the correct connection without spending a lot of time. Naturally, all the described operations should be carried out only by a qualified electrician.

Using a magnetic starter

The use of the connection diagram of the electric motor 380 through the starter is good because the start can be made remotely. The advantage of the starter over the chipper (or other device) is that the starter can be placed in the cabinet, and the controls, voltage and currents are minimal in the working area, therefore, the wires are suitable for a smaller section.

In addition, the connection using the starter provides safety if the voltage “disappears”, since the flooding of power contacts occurs, when the voltage reappears, the starter without pressing the start button does not submit it to the equipment.

The connection scheme for the starter of the asynchronous engine of the electric 380V:

On contacts 1.2.3 and the launch button 1 (open) voltage is present at the initial moment. Then it is submitted through the closed contacts of this button (when pressing the “start”) to the contacts of the starter K2, closing it. A magnetic field is created with a coil, the core is attracted, the starter contacts are closed, setting in motion the motor.

At the same time, contact NO is closed, from which the phase is supplied to the coil through the “stop” button. It turns out that when the “Start” button is released, the coil circuit remains closed, as well as power contacts.

Pressing the “stop”, the chain is torn, returning the blurry power contacts. From the supply of the engine of conductors and No, the voltage disappears.

It happens that a three.phase electric motor falls into the hands. It is from such engines that homemade circular saws, sandpaper and various kinds of grinders are made. In general, a good owner knows what you can do with him. But the trouble, a three.phase network in private houses is very rare, and it is not always possible to conduct it. But there are several ways to connect such a motor to the 220V network.

It should be understood that the engine power during such a connection, no matter how hard you try, will noticeably fall. So, the connection of the “triangle” uses only 70% of the engine power, and the “star” is even less. only 50%.

In this regard, it is advisable to have a more powerful engine.

So, in any connection scheme, capacitors are used. In fact, they play the role of the third phase. Thanks to him, the phase to which the capacitor is connected, it is shifted exactly as much as necessary to simulate the third phase. Despite the fact that one container (working) is used to operate the engine, and for launching, another (starting) in parallel from the working. Although it is not always necessary.

For example, for a lawn mower with a knife in the form of a sharpened canvas, there will be enough an unit of 1 kW and condensers only workers, unnecessarily of containers for launching. This is due to the fact that the engine is idling when starting and there is enough energy to spin the shaft.

If you take a circular saw, hood or other device that gives the initial load on the shaft, then here you can not do without additional cans of capacitors for launch. Someone can say: “Why not connect the maximum container so that there is little?»But not everything is so simple. With this connection, the motor will overheat and may fail. Do not risk equipment.

First, consider how the three.phase engine is connected to the 380V network.

Three.phase engines are both with three conclusions. for connecting only to the “star”, and with six connections, with the possibility of choosing a scheme. a star or triangle. The classic scheme can be seen in the figure. Here in the drawing on the left shows a star connection. In the photo on the right, it is shown how it looks like a real Brne Motor.

It can be seen that for this it is necessary to install special jumpers on the desired conclusions. These jumpers come with the engine. In the case when there are only 3 conclusions, the connection to the star has already been made inside the motor body. In this case, it is simply impossible to change the connection diagram of the windings.

Some say that they did this so that the workers did not stole the units home for their needs. Be that as it may, such engine options can be successfully used for garage purposes, but their power will be noticeably lower than connected by a triangle.

How the starting device works

In a state of waiting, the control circuit is de.energized, the contacts of the starting device are held by the springs at a small distance.

The principle of operation of the starter is as follows.

• After pressing the start button, the current flows through the reel winding, a magnetic field reinforced with a magnetic circuit occurs around it.
• This part of the starter acts as an electromagnet: it attracts the mobile part of the core together with the contacts.
• When the button is released, the control circuit does not open, the electromagnet reliably holds the contacts of the supply circuit in a closed state, the engine works.

When the shutdown button is activated, the throttle control circuit opens, magnetization of the magnetic circuit decreases, the springs open the contacts.

Features of connecting devices for 380 in

The choice of type, a magnetic starter connection diagram depends on the properties of the electrical installation, the conditions of its use. Distribution received the connection of electrical devices to a three.phase voltage of 380 V.

At the same time, a signal of 220 V is applied to the control throttle. Based on the conditions, needs are chosen options for connecting.

• In the simplest connection options, two buttons: to turn on. “start”, for stopping. “stop”. Are made separately with their contacts each, in one case in the form of a button post.
• Regardless of the external design of the button, have two contact sets: to start, stop. The appearance complements the ground terminal. The conclusions of the winding indicate A1, A2, the incoming terminals-L1-L3, which go out, to which the electrical installation is joined-T1-T3.
• The control voltage of 220 volts enters the conclusions A1, A2. It does not matter which of the conclusions the zero, phase wire is attached. So that the contacts of the device are not energized all the time, in everyday life they attach a fork.
• Power is supplied from the outlet. It is possible to connect the control circuit through the clock relay, temperature controllers, light flow level.

So that the control circuit does not open after returning the start button to the initial state, the seizure itself is used in the scheme.

It is implemented using auxiliary conclusions (indicated by numbers 13, 14), connected parallel to the circuit of the launch button. The disconnection is activated by the stop button, from the heat sensor signal, a decrease, lack of voltage in the outer line.

Circular Samopal.

Hello, friend of home.made!I ask the help of a collective mind.I got such a wonderful background for free. But there is a problem. when you include 220V, the motor starts to buzz in the voltage but does not spin and the attempt to pull it by the belt does not help. Manually turning easily without interclines.

What to do with him?I suspect that capacitors are needed to start. What kind?

Try to hold the start button and raise the motor (only I see you have no pens under the engine, I have to attach it). I have the same design in my country house without capacitors

We need capacitors of 7MKF per 100W engine you have 1.5. 2.2 kW for this only selection. You can so much more for starting and for work. The start.ups can be taken by electrolytes from the old tube TV, it is only desirable to take 2 and 2 times larger capacity, having coed and sequentially not boils and will not explode, and the voltage is summarized, so that with this connection (for example, the buildings) can be taken voltage from 120 and above. If it is quite tight with paper capacitors, then you can take such a battery on the working

I also want to run the engine 2.2kW from 220V. According to calculations, 160MKF is needed. Will my meter burn at 5A if 8a is written on the engine?

The very combination of the words “Circular and self.sail” is scared by me. =)

Google “Ratsuha for a ketai benzotrimmer”)) and do not scare

take me the wires that they leave the motor, and take off the cover from the button and also a photo, I’ll tell you everything.I have a workshop for rewinding motors

My dad at one time raised such a motor by the handle so that the belt was loosened and in this position he launched otherwise the capacitors did not have enough capacitors.It looks like the same system here.And the machine is dangerous sho kapets, be extremely neat with it.

Saws, milling mills and other guillotines of the limbs were separated not a little yes. He himself drove the sufferers to sew his fingers. This thing is not more dangerous than Makita with a right and respectful approach when working with it and at the same time not comparable cheaper)))

damn it, she still does not take! Urgently weld that the thread in the bottom to the corners!))) or removable mullet))

We will solve this without problems. And we weld and concrete and the table is elongated yes!

Yes, 380. but there is a connection of windings by a star or a triangle The most common. In your case, everything is more made by a triangle. because most engines are launching 220. Take a photo of an open terminal box on the engine and remove the cover on the machine too.

Thanks to. It looks like I have already figured out. Even a cut wire that goes to the capacitor. It remains to choose the capacity and design the constructive. Will live)))

In any search engine, we dial the text “How to connect the 380V engine to 220V.”and select an acceptable option.

Nowadays (having access to the Internet) there is practically no point in asking such questions It is only not to be lazy and score the necessary in the search engine:

The idea is good, but made wrong, the bed is not enough in length, or you need to screw the legs to the floor, the unstable structure came out. The connection was given a link, but the engine power will be lost.

There is no problem to weld the table and the Stannik and chill problems))) If it will be sawed as it should.

Perhaps the distance between the legs is not enough, you need to do it for stability, otherwise you will push the board more and the circular will fall.

Yes. But he worked from 220. Parents have no other voltage in the country.They already prompted the condo already.

I looked out here useful tips and decided to give my own, do not understand, do not go, take a beer or what they consume from you, call a comrade electrician and sort it out slowly.I do not see the wires that should go to the conders, which indicates that the engine may well be disabled by 380, you need to open the bourgeon and watch the shutdown that knows the electrician to help you or take a photo with the bourgeois lid removed by the lid.And in general, a dangerous design, it is necessary to lengthen the short and the table, the center of gravity is high or the engine is covered below or saw off the legs, so that it is completely under alteration!

thanks for the advice.The cable comes from it two veins, so not 380.I will finalize the construct, I have no problems according to pieces))) I will win an electrician.

Capacitors are needed.Look at the button, maybe it is with starting contact, then it’s easier to do.

Remove the belt, wind the rope, turn it on and the turfs for a rope 1500 starts without problems, 3000 with great difficulty but you can also start, and so you need to put a working and start.up capacitor,

1 thus usually let a similar hand-made
