Abstract

This paper introduces and analyses a flux reversal machine (FRM) configuration for low speed (below 150 RPM) servo drives. The FRM configuration includes stator poles with three phase concentrated coils and Zn_p alternate polarity PMs per stator pole and a salient multiple pole passive rotor. In-depth FEM analysis shows high torque density and less than 3% torque pulsation (through adequate rotor skewing) with sinusoidal three phase vector control
