| Abstract: | 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. |
