摘　　要：为解决同步磁阻电机转子结构复杂、机械强度差、难以应用于高速领域的缺点,提出了一种新型同步开关磁阻电机(synchronous switched reluctance motor,SSRM).该电机结合了开关磁阻电机与同步磁阻电机的优势,电机转子冲片制作工艺简单、可靠性强、适用于高速领域,电机的凸极率高,转矩输出能力强.在对新型SSRM电磁设计的基础上利用正交法对该电机参数进行优化,选取转矩均值、转矩脉动以及电机效率作为优化性能指标.通过有限元仿真和实验验证了优化后的SSRM具有转矩脉动低、效率高的特性.In order to solve the problem of complex rotor structure,deficient mechanical strength,and difficulty in high-speed applications of synchronous reluctance motor,a new type of synchronous switched reluctance motor(SSRM)was proposed.Taking the both advantages of switched reluctance motor and a synchronous reluctance motor,the new motor rotor was designed with several excellences including simple manufacturing process for punching sheet,strong reliability,suitable for high-speed fields,high salient pole rate and strong torque output capability.Based on the electromagnetic design of the new SSRM,the parameters of the motor were optimized by the orthogonal method,taking the average torque,torque ripple and motor efficiency as the optimized performance indicators.The finite element simulation and experiment results show that the optimized SSRM possesses the characteristics of low torque ripple and high efficiency.
