Permanent Magnet Synchronous Motor 

 

 induction motor

                                                        PMSM basic winding method 

Electrical angle = mechanical angle * number of pole pairs = magnetic declination * number of pole pairs? ?

Question 1: Does the number of pole pairs refer to the number of rotor pole pairs or the number of stator pole pairs?

Number of pole pairs = Magnets of the rotor / 2.

  

Question 2: How does the motor rotate when the stator poles of the motor do not correspond to the rotor poles?

How is the rotating magnetic field synthesized by 12 sets of coils synthesized! If you don't have any information, just draw it yourself! ! !

What is the working principle of the multi-pole-pair rotor rotating in the magnetic field generated by multiple sets of coils? ? ?

Is the electrical angle and mechanical angle related to the number of stator poles? What is the rotation angle of the magnetic field after the stator multi-poles are connected to the three-phase electricity for one cycle? (The distribution is that the winding stator poles change the mechanical angle at which the electric cycle motor rotates!!)

Question 3: How did the formula of electrical angle = mechanical angle * pole logarithm come from! !
