PM series permanent-magnet synchronous induction motor
1) high efficiency
2) smart shape
3) good controllability

PM series permanent-magnet synchronous motor have the advantage of compact structure,small size,light weight,low energy,low noise and so on.

1) The efficiency of permanent magnet motor is higher than asynchronous motor;

2) The power density of permanent magnet motor is higher than the power density of asynchronous motor;

3) The field-oriented control of permanent magnet synchronous motor is more simple than the asynchronous motor,and the control performance hardly be influenced by the change of the motor parameters
