摘　　要：针对磁阻转子定子电励磁无刷同步电机(SEEBSM)起动较慢、带负载能力不强等问题,研究了在磁阻转子内添加笼条结构对电磁性能和温度的影响。阐述了带有笼条的磁阻转子结构的工作原理以及运行方式。采用有限元方法分别研究了磁阻转子有、无笼条与不同笼条组合形式对转速的影响,以及笼条对带负载能力的影响。建立了三维稳态温度场物理模型,分别对磁阻转子有、无笼条结构下的稳态温升进行了仿真研究。研究结果表明,磁阻转子带笼条结构可以大幅度提高电机的起动性能和带负载能力,负载运行时主要结构的稳态温升虽明显增大,但仍满足绝缘等级要求。In view of the problems of stator electrically excited brushless synchronous motor(SEEBSM)with reluctance rotor,such as slow starting and low load capacity,the effect of adding cage bars inside the reluctance rotor on the electromagnetic performance and temperature is studied.The working principle and operation mode of the reluctance rotor with cage bars are described.The effect of the reluctance rotor with and without cage bars and different combination forms of cage bars on the rotation speed,and the effect of cage bars on the load capacity are studied by finite element method respectively.The three-dimensional steady-state temperature field physical model is established,and the steady-state temperature rise of reluctance rotor with and without cage bars is simulated.The results show that the reluctance rotor with cage bars can greatly improve the starting performance and load capacity.Although the steady-state temperature rise of main structure increases significantly during load operation,it still meets the requirement of insulation class.
