摘　　要：无刷双馈电机作为近年来发展起来的一种新型交流调速电机,已经得到广泛研究,由于电机具备无电刷、结构简单、运行可靠、功率因数可控、变频器的容量较小等优点。无刷双馈磁阻作为一种新型的交流电机,在变速恒频风力发电系统和交流传动节能系统具有广泛的应用前景。针对一种径向叠片磁阻转子的新型无刷双馈电机,运用软件建立其仿真模型,对其损耗进行研究,并分析温度分布,证实了此种磁阻型无刷双馈电机具有良好的工作性能。As a new type of AC adjustable-speed motor developed in recent years,the brushless double-fed machine has been widely researched.Because of its advantages of brushless,simple structure,stable running,controllable power factor and small volume converter,the BDFM has a very great prospect in variable-speed constant-frequency wind power generation system and AC energy-saving driving system.This paper describes a novel BDFM with radial-laminated reluctance rotor structure and establishes its simulation model by calculation software.The loss and temperature variation condition of the motor were analyzed.The results prove that this BDFM has good performance.
