开关磁阻电机设计方法的研究

Study of the design method of switch reluctant motor

简述了ＳＲＭ的输出特性，分析了ＳＲＭ额定工作点的电流波形，并从ＳＲＤ系统的运行特性出发，就如何满足系统的整体特性和系统协调设计的要求，对ＳＲＭ设计进行了讨论，指出电机开关角配置受转矩脉动、最佳运行效率、最佳电机材料利用率所约束，电机的过载能力和系统超调指标受电机恒功特性约束。最后给出了一设计实例。

The output characteristics of switch reluctant motor(SRM) are briefed,current waveform of SRM at rating is analyzed.Starting from the running characteristics of SRD system,the authors set discussions on the SRM design regarding how to satisfy the overall characteristics and system coordination design.It is pointed out that motor switching angle configuration is restricted by torque pulsation,optimal running efficiency and motor material utilization;motor overload capacity and overshoot index of the system are restricted by the constant power characteristics of the motor.A design example is presented in the end.
