提出了一种新型的电动汽车用永磁无刷电机。关键是将记忆电机的概念，即在线可调磁通记忆永磁电机，定子双馈双凸极永磁电机，从而实现有效的气隙磁通控制。通过进一步采用外转子和双层定子拓扑结构，该电机具有结构紧凑，电枢反应小，直接驱动能力的明确优势。越来越多地，这种电机可以提供极下降和极反转的独特功能。有限元分析，因此，计算机仿真，以验证所提出的电机的有效性。
In this paper, a new permanent magnet (PM) brushless motor is proposed for electric vehicles. The key is to incorporate the concept of memory motors, namely, the online tunable flux-mnemonic PMs, into the stator doubly fed doubly salient PM motor, hence achieving effective air-gap flux control. By further employing the outer-rotor and double-layer-stator topology, the proposed motor takes the definite advantages of compact structure, low armature reaction, and direct-drive capability. Increasingly, this motor can offer the unique features of pole dropping and pole reversing. Finite element analysis and, hence, computer simulation are given to verify the validity of the proposed motor.
