What is an Three-phase Asynchronous Motor（AC motor)? 

Types of three-phase AC motors operate at a fixed speed, synchronized with the frequency of the power supply. They are used in applications that require precise control of speed and position.Each type of motor has its advantages and is suitable for specific applications, depending on the required control, efficiency, and torque characteristics.

What is Permanent Magnet Synchronous Motor(PMSM)? 

A permanent magnet synchronous motor (PMSM) - is a synchronous electric motor whose inductor consists of permanent magnets. The main difference between a permanent magnet synchronous motor (PMSM) and an induction motor is in the rotor. Studies1 show that the PMSM has an efficiency of approximately 2% more than a highly efficient (IE3) induction electric motor, provided that the stator has the same design, and the same variable frequency drive is used for control. In this case, permanent magnet synchronous electric motors in comparison with other electric motors have the best performance: power/volume, torque/inertia, etc.
