Hello,Â
I thought that only the Br value of the permanent magnet affected the motor performance in the simulation.
As shown in the figure, in order to change the Hc value, Recoil Permeability  was arbitrarily changed from the existing 1.05 to 1, and the result of examining the no-load EMF was different.
What mechanism does it operate by?

Hello,
The performance of a motor in simulation is influenced by various properties of the permanent magnet, not just Br.
When you changed Mu, you altered the behavior of the magnet under the influence of a demagnetizing field, and the change in no-load EMF shows the recoil permeability affects the magnetic flux.For information on the relationship between permanent magnet parameters, please refer to the online help:
