摘要
介绍了一种辨识异步电机转子转动惯量的方法。该方法分为两个步骤,即:恒转矩起动和自由停机。通过记录两种状态下的时间、转速、电流等参数即可辨识出电机转子的转动惯量。以XC164CS为控制核心构建试验系统,对该方法进行验证。试验结果证明了该方法的可行性。
A method of measuring moment of inertia for induction motors is introduced. This method includes two steps, starting under constant torque and freely stopping. Moment of inertia can be identified by recording parameters of time, current and speed. Experiment system which bases on XC164CS has been built to verify the method.The results of the experiment show that the method is feasible.
