This paper describes a flux intensifying permanent‐magnet (PM) motor with variable leakage magnetic flux. The unique feature of this proposed motor is the ability to passively adjust the magnetic flux linkage into the armature windings in proportion to the armature magnetomotive force and/or armature current phase. The magnetic circuit topology of the flux intensifying PM motor and the passive variable leakage magnetic flux are determined through FE analysis. Then, the driving performance is experimentally elucidated through comparison with that of a reverse salient pole type (flux weakening) PM motor without variable leakage magnetic flux.

变漏磁通量的永磁增磁电动机的研究与实验性能评估

本文介绍了一种具有可变泄漏磁通量的磁通增强永磁（PM）电动机。该提出的电动机的独特特征是能够与电枢磁动势和/或电枢电流相位成比例地被动调节进入电枢绕组的磁通链。通过有限元分析，确定了磁通增强永磁电动机的磁路拓扑和无源可变漏磁通。然后，通过与无可变漏磁通的反凸极型（弱磁）PM电动机进行比较，从实验上阐明了驱动性能。
