Abstract

Flux-switching permanent magnet (FSPM) machine is a novel double salient structure PM machine with both concentrated armature windings and magnets in the stator, which attracts much attentions due to its high torque density and fault tolerance. However, the back-EMF of traditional FSPM is not perfectly sinusoidal, due to the influence of harmonics, which causes the torque ripple. Hence, in this paper, two shapes of stator teeth will be proposed, and the results of the two-dimensional finite-element analysis (2-D FEA) will be compared. Finally, the optimal stator tooth scheme will be obtained.
