本文提出并分析了一种新型直接驱动双转子游标永磁（DR-VPM）电机。设计的关键是在保持电机体积和槽数不变的情况下，将两个同心转子和游标结构集成在一台永磁电机中。该电机的主要优点是结构紧凑，提高了转矩密度，减少了定子端部绕组长度，降低了铜损。讨论了该电机的工作原理，并采用电路-场-运动耦合时步有限元法（CFM-TS-FEM）对其稳态和瞬态性能进行了分析。采用CFM-TS-FEM方法设计了双励磁永磁游标电机和单外转子永磁游标电机，并与该游标电机进行了比较。报告的比较结果用于确认和验证所提出的机器的有利性能。
In this paper, a novel direct-drive double rotor Vernier panent magnet (DR-VPM) machine is proposed and analyzed. The key of the design is to incorporate two concentric rotors and the Vernier structure within one permanent magnet (PM) machine, while keeping the machine volume and slot number unchanged. The main merits of this proposed machine are its compact structure, improved torque density, reduced stator end winding length, and reduced copper loss. The operating principle of the machine is discussed and its steady and transient performances are analyzed using circuit-field-motion coupled time-stepping finite element method (CFM-TS-FEM). A dual-excitation PM Vernier (DE-VPM) machine and a single outer rotor PM Vernier (SR-VPM) machine are designed and compared with this proposed Vernier PM machine using CFM-TS-FEM. Comparison results as reported are used to confirm and validate the advantageous performance of the proposed machine.
