A Novel Stator and Rotor Dual PM Vernier Motor With Space Vector Pulse Width Modulation

In this paper, an electric machine with dual permanent magnet (PM) structures in both stator and rotor is proposed. Multi-pole PMs are buried both in stator and rotor slots of the proposed machine and the magnetic field is modulated through the stator and rotor teeth. This machine with dual magnetic flux modulation can be categorized as one special case of flux-modulating machines. A time-stepping finite-element method combined with space vector pulse width modulation-based vector control method is used to analyze the steady-state and transient performance of the machine and its control system.
