A Novel Hybrid Magnet Dual-Stator Vernier Machine with Flux-Reversal Magnet Arrangement

This paper proposes a novel hybrid magnet dual-stator vernier machine with flux-reversal magnet arrangement (HM- FRDSVM) featuring NdFeB and ferrite magnets mounted on outer and inner stator tooth tips, respectively. Flux-reversal magnet arrangement is adopted on both of inner and outer stators to achieve high efficiency and power density. The proposed topology, operating principle are described, together with the electromagnetic characteristics analyzed. The result shows that the proposed machine is appealing choice which has high torque cost coefficient and low torque ripple.
