WebPMSMs are classified into two categories depending on the rotor construction: 1. Surface Mount:The magnets are mounted on the surface of the rotor. They need special profiling to get a sinusoidal Back EMF (BEMF). This results in a symmetrical air gap reluctance for the magnetic flux path. WebA reactance torque of PMSM is generated by an interaction of two magnetic fields (one on the stator and one on the rotor). The stator magnetic field is represented by the magnetic flux/stator current. The magnetic field of the rotor is represented by the magnetic flux of permanent magnets that is constant, except for the field weakening operation.
