| 摘 要： | 为解决异步电机在电压型变频器驱动下制动困难的问题，试验一种新型的异步电机三相／二相制动方法。根据异步电动机本身非线性的动态数学模型，构造出两相静止坐标系下基于MATLAB环境的异步电机三相／二相制动仿真模型。通过对异步电机三相／二相制动的动态过程仿真，详细分析了电压型变频器驱动下的异步电机能进行三相／二相制动的原因，同时验证了这一仿真模型的正确性。

| Abstract: | This paper introduces a new three phase/two phase brake experiment, for surmounting the brake difficulty of induction motor under the drive of voltage source frequency inverter. According to dynamic math model of nonlinear of induction motor, a simulation model for induction motor three phase/two phase brake based on two phase static coordinate is constructed by using MATLAB. It analyzes the reason that induction motor under the drive of voltage source frequency inverter can brake with three phase/two phase in details. And the validity of the simulation model is tested and verified via the simulations. |
