单相电动机离心开关断开转速的微机测试

Microcomputer Measurement on Centrifugal Switch Breaking Speed of Single Phase Motor

介绍了单相电动机离心开关断开转速的微机测试系统,该系统利用单板机控制,以电动机起动电流作为开关断开信号。具有操作方便,精度高,显示准确等优点,特别适用于出厂试验在线的检测,为工厂贯彻国家标准提供了先进的测试手段,同时还能显示断开时间和完成离心开关本身断开转速的测试。

The paper introduced a microcomputer measuring system that takes measurement of the cen-triffugal switch breaking speed of single phase induction motor. In this system, a single -board computer was used as control unit and the motor start current acts as signal of the centrifugal switch breaking. This system has such advantages as simply operating, high perecision and accurately display. It is particularly suitable for on-line testing for motors . It supplied advanced measure method for factories earring out national standard. The measuring system can also display breaking time of the centrifugal switch, and , take measure of centrifugal switch breaking speed.
