Permanent magnet synchronous motor is a motor made of permanent magnet materials and excited by permanent magnets to generate a magnetic field.

Permanent magnet synchronous motor is a motor made of permanent magnet materials and excited by permanent magnets to generate a magnetic field. It is mainly composed of stator, rotor, casing, front and rear end covers, bearings, etc.

Structural features of permanent magnet synchronous motor:

★The structure of the permanent magnet synchronous motor is basically the same as that of the ordinary asynchronous motor, and the main difference is the rotor.

★The rotor surface (SPM) or internal embedding (IPM) has pre-magnetized (magnetized) permanent magnet material, which can provide the necessary air gap magnetic field for the motor.

★Advantages: effectively reduce the size of the motor, reduce losses and improve efficiency.

The motor cannot rotate after being energized, but there is no abnormal noise, odor and smoke.
