Abstract

This paper presents a five-phase permanent magnet (PM) vernier machine topology equipped with a two-slot pitch winding. The two-slot pitch winding provides a trade-off between fractional slots concentrated winding (FSCW) and integrated slot distributed winding (ISDW) PM vernier machines. First, the development and basic structure of the fivephase PM vernier machine with auxiliary teeth are depicted. Then, the PM vernier machine with proposed two-slot pitch fractional slot winding is explained. Finally, the five-phase PM vernier machines with conventional ISDW and FSCW configuration are analyzed and compared with the proposed PM vernier machines with two-slot pitch fractional slot winding. The benefits of introducing two-slot pitch windings are quantitatively analyzed and verified by finite-element analysis (FEA). This analysis confirms that a higher back EMF and torque density can be achieved in this topology while keeping a reasonable power factor.
