As a rule, for connection of three phase motor uses three wires and a supply voltage of 380 volts. The network is 220 volts with only two wires, so the engine has started, the third wire also need to apply tension. For this purpose, the condenser, which is called a condenser.

The capacitance of the capacitor depends on the power of the engine and is calculated by the formula:
C=66*P, where C is the capacitance of the capacitor, UF, P – electric motor power, kW.

That is, for every 100 watts of power the engine needs to pick up about 7 µf of capacitance. Thus, for the engine power of 500 watt need a capacitor with a capacitance of 35 µf.

The required capacity can be assembled from several smaller capacitors by connecting them in parallel. Then the total capacity is counted by formula:
Sobsch = C1+C2+C3+.....+Cn

It is important to remember that the working voltage of a capacitor should be 1.5 times the motor power. Consequently, when the supply voltage is 220 volts, the capacitor must be 400 volts. Capacitors you can use the following type of KBG, MBGC, OSH.

3
For motor connection use two connection schemes is the "triangle" and "star".
4
If the three-phase motor has been connected according to the scheme "triangle", then to single-phase network connected on the same circuit with addition of capacitor.
5
Motor connection star performed according to the following scheme.
6
For the operation of the motors power up to 1.5 kW is sufficient capacitance of the operating capacitor. If you connect the engine more power, this engine will be very slow to accelerate. It is therefore necessary to use a starting capacitor. It is connected in parallel with the working capacitor and is used only during acceleration of the engine. Then the capacitor is disconnected. The capacitance of the capacitor to run the motor needs to be 2-3 times more than the capacity of the worker.
7
After starting the engine, determine the direction of rotation. It is usually necessary that the motor rotate clockwise. If the rotation is in the right direction to do nothing. To change direction, you must do the rewiring of the engine. Disconnect any two wires, swap them and reconnect. The direction of rotation will reverse.

When performing electrical work observe safety regulations and use the individual means of protection against electric shock.
