定子叠片式外转子横向磁通永磁电机设计

Design of an Outer Rotor Transverse Flux Permanent Magnet Motor with Laminated Stator

横向磁通永磁电机具有较传统永磁电机更高的转矩密度,但其存在漏磁与齿槽转矩大等不足。为了实现兼顾抑制其漏磁和齿槽转矩的研究目标,论文开展定子叠片式外转子横向磁通永磁电机的设计研究,首先介绍建议的外转子横向磁通永磁电机拓扑结构并建立其三维有限元仿真分析模型;然后通过在永磁体周向设置间隙和定子间设置辅助定子相结合,并对永磁体周向间隙和辅助定子进行优化的措施,确定定子叠片式外转子横向磁通永磁电机设计方案。最后,加工制造了样机,通过样机的实验测试证实设计方案的合理有效性。

The transverse flux permanent magnet motor(TFPM)has higher torque density than the traditional permanent magnet motor, however, it is also faced with the weakness of high cogging torque and flux leakage. Therefore, an outer rotor TFPM with laminated stator is designed by taking consideration of reducing both flux leakage and cogging torque. First, the topology of proposed TFPM is introduced and the 3D-FEM analysis model is set up. Then, the gap between adjacent magnets and auxiliary stator between stators are applied, further, the outer rotor TFPM design scheme is been decided after the gap and the auxiliary stator are optimized. Finally, the prototype is been built and the prototype experiments are implemented to validate the effectiveness of TFPM design scheme.
