Hello, 

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 several factors, including the magnetic properties of the permanent magnet used. While the residual flux density (Br) is indeed a critical parameter as it indicates the available flux output from the magnet, the coercivity (Hc) also play significant roles. The relationships between the four properties of a permanent magnet are explained in the following online help:
