摘要

This paper proposes a novel dual-permanent-magnet-excited (DPME) machine, in which two sets of permanent magnets (PMs) are employed, one on stator and the other on rotor. Bi-directional field modulation effect (BFME) is artfully engaged to guarantee the effective coupling between the magnetic field excited by the armature windings and those excited by the two sets of PMs. Machine configuration and its operating fundaments are elaborated. Finite element analysis demonstrates that the proposed DPME machine can offer much higher torque capability than its existing counterparts, which allows it a strong competitor for low-speed large-torque applications.
