摘要 该文对比分析了两种典型的场调制型永磁电机,即常规永磁游标电机和双永磁励磁电机的性能和特点。首先介绍两种电机的结构,总结它们的结构特点;接着通过推导两种电机的一般性表达式,即空载反电动势及输出转矩,揭示两种电机的工作原理,比较“单向磁场调制效应”与“双向磁场调制效应”;最后利用有限元法对比分析两台电机的性能,验证一般性表达式的正确性。有限元仿真结果表明,在相同的尺寸、定子槽数、定子齿数、绕组极对数、转子磁体极对数、线圈匝数、绕组联结方式、电负荷、铜损耗及转速的条件下,双永磁励磁电机在永磁体用量、反电动势、转矩密度、单位磁体体积的转矩、功率因数及效率方面优于常规永磁游标电机。

Abstract:In this paper, the performance and characteristics of two typical field modulated permanent-magnet machines (FMPMs), i.e. regular permanent-magnet vernier machine (PMVM) and dual permanent-magnet-excited machine (DPMEM), were compared and analyzed. Firstly, the structures of the two machines were introduced and their structural characteristics were summarized. Next, by deducing the general expressions of the two machines, i.e. no-load back electromotive force (EMF) and output torque, their working principles were revealed, and the “unidirectional field modulation effect (UFME)” and “bi-directional field modulation effect (BFME)” were compared. Finally, by finite element method (FEM), the performance of two machines was compared and analyzed, and the correctness of the general expressions was verified. The results of FEM simulation show that under the same size, number of stator slots and stator teeth, pole-pair number (PPN) of windings and rotor permanent magnets (PMs), turns of each coil, winding connection, electric load, copper loss and rotational speed, the DPMEM is superior to the regular PMVM in terms of PM consumption, back EMF, torque density, torque per unit volume of magnet, power factor and efficiency.
