| 摘 要： | 应用小波变换方法从实测的异步电动机定子起动电流中提取一阶转子齿谐波分量,然后利用小波包良好的时-频定位性能,从齿谐波中提取异步电动机起动转速和转矩信息,得到异步电动机的转矩-转速特性.理论分析、计算机仿真和实验结果表明,该方法可实现无传感器间接测试异步电动机的起动特性.

| Abstract: | In this paper, the frequency of first-order slot harmonic was abstracted from stator's starting current of a induction motor. The starting torque and speed was acquired by analysing the first-order slot harmonic based on wavelet package transform which has the character of excellent time-frequency location. Finally starting torque-speed charactefistcs of induction motor was acquired. The theory, simulation and test result testify that this method can accomplish the sensorless measurement of induction motor. |
