摘要
在分数槽集中绕组(FSCW)永磁电机的基础上进行了定子模块化改造,设计了四种不同的定子模块化结构,包括非隔磁类(T型、齿轭分离型)、隔磁类(E型、C型),以及缠绕齿和非缠绕齿不同时带齿尖的两种新型齿尖结构。建立相应的有限元电机模型,研究探讨了定子模块化类型与齿尖结构对FSCW永磁电机性能的影响。仿真结果表明模块化结构永磁电机选取合适的定子间隙可降低齿槽转矩。12槽10极电机采用的缠绕齿带齿尖结构可提高电机性能。
Based on the fractional slot concentrated winding(FSCW)permanent magnet motor,the stator modular transformation is carried out,and four different stator modular structures are designed,including nonmagnetic isolation type(T type,yoke separation type)and magnetic isolation type(E type,C type).At the same time,two new tooth tip structures in which winding teeth and non-winding teeth do not have tooth tips simultaneously are designed.The corresponding finite element motor model is established,and the effect of stator modularization and tooth tip structure on the performance of the FSCW permanent magnet motor is studied.The simulation results show that the suitable stator gap of the modular structure permanent magnet motor can reduce the cogging torque.The 12-slot 10-pole motor adopting the structure of winding teeth with tooth tips has better motor performance than the other structures.
