摘　　要：磁通切换电机作为一种无刷电机,其定转子采用双凸极结构,转子仅由硅钢片叠压而成,定子内置有集中绕组和永磁体,运行时只需一组功率开关器件和二极管即可实现电机的控制,因此,具有结构简单、控制方便、可靠性高等优点,广泛应用于风机泵类等高速负载。该文提出一种铁氧体永磁单相磁通切换电机结构,并对该电机的基本结构和工作原理进行深入分析。根据电机性能目标,对其进行电磁设计,确定电机几何尺寸参数,并提出消除该电机起动死区的转子分段结构方案。与一台尺寸相同的电励磁单相磁通切换电机进行全面对比,验证所提电机在静态性能和瞬态性能上的优势。最后制作样机,并对所提出电机进行实验测试。As a type of brushless motor,the flux switching motor has a double salient construction of stator and rotor.The rotor is laminated by silicon steel sheets,while the stator contains concentrated windings and permanent magnets.Thus,only one set of power-switching devices and diodes are needed to control the motor.In this paper,a ferrite permanent magnet single-phase flux switching motor structure is proposed,and its basic construction and working principle are analyzed.According to the design criteria of the motor,the geometric parameters are determined,and the segmented rotor is proposed to eliminate the starting dead zone of the motor.A comprehensive comparison with an electromagnetic single-phase flux switching motor of the same size is performed to verify the advantages of the proposed motor in static and transient performance.Finally,a prototype is fabricated and tested.
