Abstract—A permanent magnet synchronous motor (PMSM) with rotor embedded segmented permanent magnet was analyzed. The structural features and flux weakening principle are introduced. The shape of the rotor is optimized to get a sinusoidal air gap magnetic density waveform and reduce the toque ripple. The whole-permanent-magnet (PM) motor and the segmented-permanent-magnet motor are compared from the aspects of the no-load performance, the rated load performance and the flux-weakening performance by finite element method (FEM). The theoretical analysis and simulation by FEM indicate the availability and validity of flux-weakening for the segmented-PM motor.

Index Terms—permanent magnet synchronous motor; segmented permanent magnet; d-axis inductance; flux weakening
