传统的磁通反转永磁电机存在极漏磁大的问题，导致永磁体利用率低，主磁通减少。本文提出了一种同极式玻璃钢RPM机，它的磁铁使用量是传统玻璃钢RPM机的一半。然而，由于极漏磁通的减少，建议的机器具有更大的反电动势和转矩比传统的。本文介绍了该电机的工作原理和减少磁极漏磁的机理。此外，与就业的有限元分析，所提出的机器的电磁性能进行评估和定量比较与传统的FRPM机的气隙磁通密度，磁链，反电动势，脉动转矩，额定转矩，损耗，弱磁和过载能力。
Conventional flux-reversal permanent-magnet (FRPM) machines suffer from large pole leakage flux, which leads to the poor utilization of PMs and reduction of main flux. This paper proposes a consequent-pole FRPM machine, whose magnet usage is halved compared with that of a conventional FRPM machine. Nevertheless, due to the reduction of the pole leakage flux, the proposed machine exhibits larger back EMF and torque than that of the conventional one. In this paper, the operation principles and mechanism of reduced pole leakage flux of the proposed machine are introduced. Moreover, with the employment of finite-element analysis, the electromagnetic performances of the proposed machine are evaluated and quantitatively compared with a conventional FRPM machine in terms of airgap flux density, flux linkage, back EMF, pulsating torque, rated torque, losses, and flux-weakening and overload capabilities.
