【摘要】 在测量步进电动机绕组电感时,采用了改进的di/dt法,在被测绕组中通以工频交流电流,可以同时测出电流上升和下降时的电感值。即考虑了磁滞涡流效应在测试过程中的影响。本文着重介绍在采用这种测量方法时所涉及的数据处理的主要问题及处理方法。包括符号恢复,消除“毛刺”,数据平滑及数据校正等。应用所述的测量方法及数据处理程序,实测混合式步进电动机绕组的电感,效果很好。更多还原

【Abstract】 To measure the winding inductance of step motor,the improved di/dt methodis adapted.While a 50 Hz current flows through the winding,the inductancevalue with the current decreasing and increasing is measured,therefore effectof hysteresis and eddy current is take into account. This paper introduces the data processing related to applying this method,including how to restore the data sign,to eliminate the "bad point",to smoothand regulate the data,etc.By utilizing the described method and data processingprogram,it is very effective to the winding inductance measurement of hybridstep motor.更多还原
