Permanent Magnet Motor

Permanent magnet motor is a rectangular pulse, current sine wave current, hybrid permanent magnet motor forms.

Structure of permanent magnet motor and permanent magnet materials


Forms for permanent magnet motors are: 

(1) the rectangular pulse current, permanent magnet brushless DC motor PMBDC with rectangle pulse wave current. 

(2) the sinusoidal current, permanent magnet reluctance synchronous Motors PSM with sinusoidal current. 

(3) hybrid permanent magnet motor.


Permanent magnets:

(1) rare earth samarium-cobalt: maximum energy density.

(2) ND-Fe-b: resources, good processability.
