摘要
根据永磁直线同步电动机的特点,建立了基于dq坐标系统的永磁直线同步电动机数学模型,推导了电机的运动方程和状态方程。在MATLAB环境下对起动过程进行了仿真,并对初级电抗、负载阻力以及励磁电势等参数变化对电机起动过程的影响作了仿真,仿真结果为永磁直线同步电机结构参数的进一步优化设计提供了参考。
Mathematical model for permanent magnet developed and presented. Based on the mathematics synchronous motor by using d. q. coordinates has been model the starting process had been simulated in MATLAB/SIMULINK and the effect of electromagnet parameters is discussed. The research shows that these parameters have great effect on the starting and the results of simulation are valuable for the design and optimize of motor structure and parameters.
