摘要
本文根据自适应滤波的原理,推导出处理鼠笼转子异步电机定子电流的方法。经过仿真计算和对转子有断条的电机定子电流的处理,结果表明:用本方法可以大大提高检测转子断条故障特征分量的灵敏度。
The paper presents a method of processing the stator current of squirrel cage induction motor with broken rotor bar.The method is based on the theory of ada- ptive filter.Results of numerical simulation and processing of the actual stator current show that the presented method improves the sencitivity of extracted feature component and makes the detection of rotor broken bar in squirrel cage induction motor more exact.
