摘要:交流电动机，特别是鼠笼型异步电动机，结构简单，成本低，维护方便，而且坚固耐用，惯量小，运行可靠，对环境要求不高，因此在工农业生产中得到了极广泛的应用。其突出的优点是，电机制造成本低，结构简单，维护容易，可以实现高压大功率及高速驱动，适宜在恶劣条件下工作，并能获得和直流电机控制系统相媲美或更好的控制性能。

　　本文主要对笼型异步电机进行了模型分析，利用坐标变换原理得出了其在α β 坐标系下的动态数学模型，并用simulink 仿真工具对其进行了动态仿真。仿真结果证明了模型的正确性。

Abstract:AC motor, squirrel cage induction motor, simple structure, low cost, easy maintenance, and rugged, the inertia is small, reliable operation, less demanding on the environment, a very wide range of applications in industrial and agricultural production . Prominent advantage is that the motor manufacturing low-cost, simple structure, easy maintenance, high-voltage high-power and high-speed drive can be achieved, suitable for working in harsh conditions, and DC motor control system is comparable to or better control performance.

The This article mainly right the cage type asynchronous motor carried out model analysis of, the use of that the Principle of Coordinate Transformation to drawn the its dynamic mathematical model of under the in the alpha β coordinate system, and use the simulink simulation tool of its carried out the a dynamic simulation. The simulation results prove the validity of the model.

Keywords: MATLAB; squirrel cage induction motor; simulation
