本文提出了一种新型双永磁励磁（DPME）电机，其中采用两组永磁体（PM），一组位于定子上，另一组位于转子上。巧妙地利用双向场调制效应（BFME），保证电枢绕组激发的磁场与两组永磁体激发的磁场之间的有效耦合。详细阐述了机器的配置及其操作原理。有限元分析表明，所提出的 DPME 机器可以提供比现有同类机器更高的扭矩能力，这使其成为低速大扭矩应用的强大竞争对手。
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.
