Abstract

In this paper, two novel asymmetric variable flux memory machines with U-type permanent magnet (PM) configurations are proposed. These designs feature variable PMs (VPMs) placed on one side and constant PMs (CPMs) on the opposite side of the U-shaped cavity, with or without additional VPMs in the middle cavity. Both machines are firstly designed and optimized using finite element method with the same 21-slot/4-pole stator and rotor inner/outer diameters. The electromagnetic performance of the optimized designs are analyzed and compared. Results show that the middle VPMs can enhance the flux regulation (FR) capacity but contribute less to the torque. As a result, the machine with the middle VPMs can achieve a wide FR range and improved overall efficiency, whereas the machine without the middle VPMs can deliver higher torque density. Finally, two prototypes are fabricated and tested for validation.

具有u型PM结构的新型非对称可变磁通存储器

本文提出了两种新型的u型永磁结构的非对称可变磁通存储器。这些设计的特点是在u型腔的一侧放置可变pm (vpm)，在另一侧放置恒定pm (cpm)，在中间腔中有或没有额外的vpm。首先采用有限元法对两种电机进行了设计和优化，定子和转子的内外直径均为21槽/4极。对各优化设计的电磁性能进行了分析和比较。结果表明，中间VPMs可以提高磁链调节能力，但对转矩的影响较小。因此，具有中间VPMs的机器可以实现更宽的FR范围并提高整体效率，而没有中间VPMs的机器可以提供更高的转矩密度。最后，制作了两个原型并进行了验证测试。
