Three Phase Synchronous Motor

three phase synchronous motor

The operation of the three-phase synchronous motor can be summarized as follows:

Three-phase AC voltage is applied to the stator windings and a rotating magnetic field is certainly produced.

DC voltage is applied to the rotor winding and a second magnetic field is certainly produced.

The rotor then acts like a magnet and is attracted by the rotating stator field.

This attraction exerts a torque on the rotor and causes it to rotate at the synchronous speed of the rotating stator field.

Runs at main power net (three phase,380v,50HZ) Without inverter.

High performance : The rotor uses rare earth PM material. High magnetic field tensity, big starting torque, small starting current, and wide speed range;

Small size and light weight : Its frame size is one to two frame sizes smaller than that of AC asynchronous motor of same HP;

High efficient and high power factor, effective in saving energy : it is 5% to 12% more efficient than asynchronous motor of same HP. As the motor does not need the exciting current, the power factor is close to1;Save about 10% Energy than asynchronous motor.

Long durability : As a result of reduced current and less heating of motor;

Compatibility : It has same frame structure with AC asynchronous motor and can be used to substitute AC asynchronous motor;

Wide applicability : It can be used in various tough conditions.
