Abstract :
Vernier permanent magnet (VPM) machines are obtaining more and more attentions due to their high torque density and low torque ripple in recent years. However, they suffer from low power factor compared with conventional PM machines. In this paper, a triple-rotor axial-flux spoke-array vernier permanent magnet (TR-AFSAVPM) machine is proposed to improve the power factor of conventional VPM machines to a reasonable level as well as maintaining high torque density and adequate speed range. Both Quasi-3D finite element Analysis (FEA) and 3D-FEA are employed to investigate the performances, such as power factor, torque density and torque ripple of the proposed machine.
