摘　　要：设计了三相异步电动机定子磁场的Matlab动画仿真系统,系统以单层整距绕组为例,将基波磁动势绘制在定子圆周上形成旋转磁动势,同时确定各电流方向相同且相邻的绕组边分组。依据右手定则绘制其磁场,并在循环中每个时刻进行刷新以达到旋转效果。该系统可通过Matlab GUI界面灵活设置不同的绕组参数和电气参数等数据,全面展示在这些参数下绕组布置和定子磁场运行的动画,直观地反映电机定子磁场所满足的相关规律。通过在教学中演示该动画,能更有效地帮学生建立旋转磁场等概念,改善教学效果。A matlab animation system for the stator magnetic field of the motor is designed to assist teaching.Taking the single-layer integral moment winding as an example,the magnetomotive force(MMF)of the stator is drawn on the circumference to form the rotating MMF in the animation.At the same time,the adjacent winding edges with the same current direction are grouped,and the magnetic field is drawn according to right-hand rule,and updated at every moment of the cycle to achieve the rotation effect.Different winding and electrical parameters can be set through the Matlab GUI interface and the animation of winding layout and stator magnetic field operation under these parameters can be fully displayed,which intuitively reflects the relevant laws satisfied by the magnetic field.By demonstrating the system in teaching,it can help learners establish concepts such as rotating magnetic field more effectively,and the learning effect is improved.
