Synchronous motor is an AC motor with the same rotating speed as the stator rotating field. The rotation speed of the rotor is n=60f/p with the logarithmic p and the power frequency .
The speed n depends on the power frequency f, so the power supply frequency must be constant, the speed is constant, and it has nothing to do with the load. It has the characteristics of high operation stability and overload capacity.
It is often used in multi-machine synchronous transmission system, precision speed control system and large equipment.

Synchronous machine structure
The structure of synchronous motor is varied, and the rotor structure has hidden pole type and salient pole type. The installation methods include horizontal, suspension, semi-suspension and vertical.
The synchronous motor is usually composed of stator, rotor, bearing, baseplate, end cover, collector ring and brush frame, and the motor with the protection grade of IP44 is also included in the cooler. A brief description of the above components is given below:
