摘要
与串激电动机配套用的测速传感器是高档滚筒洗衣机实现电动机智能化控制的关键环节。设计的感应线圈检测系统,利用无刷直流电动机转速范围大、控制可靠等特点,通过把感应产生的交流电压经过全波精密整流电路处理成直流电压信号,供计算机采集处理,从而实现对感应线圈性能的检测。经实验验证,该系统具有运行可靠,控制方便、稳定性好和测量精度高等优点。
The speed sensor matching for series excitation electrical machine is where the key components to realize the motor intellectualized control in advanced platen washing machine.Designed the parameter measuring system for inductive loop,by using the characteristic of Brushless DC Motor（BLDCM） which can turn speed widely and control reliably,the alternating inductive current can appear when magnetism stage is turn with BLDCM,and the DC voltage is imported into computer,realized the aim of testing the performance of inductive loop at last.The experiment indicated that the parameter measuring system have advantages such as reliable operating,easily control,well stability and higher precision.
