摘要
外贴式永磁同步电动机采用变频器供电,结构简单,控制方便。建了变频电源供电时永磁同步电动机的数学模型,对传统的机械运动方程进行了修正,使其更接近启动过程的实际情况。在此基础上,应用 MATLAB 语言编制了计算机仿真程序,用于分析电机不同工况时的瞬态性能和参数变化对动态性能的影响,并对一台 5.5 kW 的电机进行了仿真,结果证明修正后的数学模型是正确的。
permanent magnet synchronous motor which is sticked outside of frequency variation power possesses simple structure and convenient control. Mathematical model for it is developed in this paper. In order to comply with the real starting process, the traditional state variable formulations are corrected. On this basis, computer simulation program with MATLAB language is working conditions and the impact on dynamic performance when the parameter is changing. At last, a motor of 5.5 kilowatts is simulated, and the effects of the simulation prove that the mathematical model is right.
