Dear all

I am Joey.

I am simulating a permanent magnetic motor with rmm physics. I need the torque, the rotational speed of rotor, should I define a parameters before calculating? Also, if you know more about motor, I am learning about the way of controling the pm-motor, hope you can share your idea with me.

Regards

Dear Joey,

     you can follow this tutorial:
     https://www.comsol.com/model/generator-in-2d-2122
     you can modify the induction motor to a PM combinig the precous tutorial with:

     I've made it in the past but unfortunately it is propietary IP so I cannot give you a model...

     Kind regards,

     Julian
