A permanent magnet synchronous motor (PMSM) is a motor that uses permanent magnet
A permanent magnet synchronous motor (PMSM) is a motor that uses permanent magnet materials and is excited by a magnetic field generated by permanent magnets. It is mainly composed of a stator, rotor, casing, front and rear end covers, and bearings.
Structural characteristics of permanent magnet synchronous motors:
★ The structural form of a permanent magnet synchronous motor is basically the same as that of an ordinary asynchronous motor, the main difference being in the rotor.
★ The rotor surface (SPM) or interior (IPM) has pre-magnetized permanent magnet materials that provide the necessary air gap magnetic field for the motor.
★ Advantages: Effectively reduces motor size, reduces losses, and improves efficiency.
