摘要
介绍一种交直交变频调速传动系统中异步电动机电参量的测试方法，微机与可程控仪器构成的自动测试系统为实现对非正弦信号的采样和分析提供手段，准同步采样技术较好地解决了难以实现同步采样情况下的非正弦量的测量问题，同时利用ＦＦＴ算法实现了谐波参数和转矩的测量．
It is introduced the test method of asynchronous motor electric parameters in AC-DC-AC variable frequency speed control drive system. The automatic test system composed of microcomputer and program controlled instruments help realize the sampling & analysing of non-sine signals. Quasisynchronous sampling technique has solve the problem of non-sine signal test rather satisfactorily which is difficult under synchronous sampling condition. FFT algorithm facilitates the testing of harmonic parameters and torque.
