To use 3 phase motor on 1 phase power supply, we can connect any 2 phase winding coils in series, and then connected to the other phase. When the three phase asynchronous motor uses single phase power supply, the power is only 2/3 of the original. According to this principle, we can use the three phase winding of the three phase asynchronous motor, and shift one of the winding coils with a capacitor or inductance, so that the two phase can go through a different current to establish a rotating magnetic field to operate the motor. So the single phase motor stator should not only have a working winding, but also must have a starting winding. If it tries to produce a different phase current, the two phase current has a certain phase difference in time to produce a rotating magnetic field. However, the position of the two windings inside the motor has a different angle of space. In this case, the pulsating magnetic field of the stator interacts with the current in the rotor conductor cannot generate torque because there is no rotating magnetic field, so that the motor cannot be started. In other words, it is fixed in terms of the stator.

The reason why it has no initial starting torque is because single phase winding in the magnetic field is not rotating but pulsating. Before talking about the usage of three phase asynchronous motor being converted to work on single phase power supply, we should explain the issue of establishing single phase asynchronous motor rotating magnetic field, because single phase motor can be started only after the establishment of rotating magnetic field. Three phase asynchronous motor uses three mutually separated 120° angle of the balanced current through the stator winding to produce a time-varying rotating magnetic field to drive the motor.

Here will show you how to convert 3 phase 380v motor to run on single phase 220v power supply. It has some works to do to convert 3 phase motor work on 1 phase power supply. In the case to run the three phase machines on single phase power supplies, there are 3 ways to do it: 3-phase AC motor uses 3 phase power supply (3 ph 220v, 380v, 400v, 415v, 480v etc.), but in some actual applications, we have single phase power supplies only (1 ph 110v, 220v, 230v, 240v etc.), especially in household appliances. Three phase asynchronous AC motor is widely used in industrial and agricultural production due to its simple structure, low cost, easy maintenance and easy operation.
