单段反应式步进电动机主要特性的仿真

Simulation of main characteristics of single-segmented variable reluctance step motor

为深入地认识反应式步进电动机的内部特性 ,对单段反应式步进电动机主要特性进行了仿真。仿真采用的是MATLAB语言及其中的SINMLINK仿真工具 ,特别是S -function。虽然步进电动机的使用较为简单 ,但由于体积小 ,其电磁特性颇为复杂 ,在仔细分析单段反应式步进电动机的电感基础上 ,对电流、转矩进行了仿真 ,并进一步得到了步进电动机的矩频特性。

For know the inner of variable reluctance step motor deeply,the main characteristics of the step motor is si- mulated.The MATLAB and SIMULINKare used during the simulation,especially the S-function.On the basis of carefully analyzing the inductance,the current and torque are simulated,further the frequency and torque characteristics are known.
