Features:

1) It can start on its own and can smoothly pull in synchronization without starting winding or other starting device.

2) The rotor has no magnetic pole structure and does not need to be pre-magnetized. Its magnetic pole is magnetized by the rotating magnetic field of the stator, which is convenient for designing a multi-pole motor.

3) From starting, running to entering synchronization, from no-load operation to output maximum synchronous torque, the input current is almost constant, but the power factor is low.

4) No sliding contact, the motor has simple structure, low cost, reliable operation, high mechanical strength and low running noise.
