摘　　要：异步电机的动态数学模型为一个高阶、强耦合、非线性的多变量系统,且在非正弦供电变频装置下运行,传统的分析方法很难适应这样复杂系统的分析。为了简化电机的研究方法,对三相异步电机模型进行分析,利用坐标变换原理推导出其在αβ0坐标系下的动态数学模型,通过Matlab软件中的Simulink组件建立电机的数学模型,研究与仿真了电机在理想空载与满载时的启动过程。结果表明Simulink能高效、较准确地对电机进行仿真。The dynamic mathematical model of asynchronous motor is a high-order, strong-coupling, nonlinear and multivariable system, it runs in the non-sinusoidal power supply frequency conversion device, which makes the traditional analysis method difficult to adapt to such a complex system. In order to simplify the research method for the motor, the three-phase induction motor model is established. The dynamic mathematical model under αβ0 coordinate is derived by using the coordinate transformation principle. Through the Simulink of the Matlab soft-ware, the mathematical model of the motor is established. The research and simulations on the startup process of the motor under the ideal no-load and full-load conditions are presented. The simulation results show that the Simulink software can simulate the motor efficiently and accurately.
