Design Considerations of Stator DC-Winding Excited Vernier Reluctance Machines Based on the Magnetic Gear Effect

Stator dc field winding excited vernier reluctance machines are increasingly attracting research interest recently due to their low cost and highly reliable rotor structure. In this paper, the design of these machines is studied systematically using both theoretical equations and finite element analysis (FEA). First, the general structures of these machines and their operation principles are discu...
