基于单片机的单相电动机调速方法及其实现

Approach and Realization of Speed-adjusting for Single-phase Motor Based on Singlechip

介绍了在三抽头单相电动机中采用分时接通的方法增加电动机的转速档次,使电风扇具有二十四档转速的调速能力和更好的节能效果,这种调速方法无须增加较多的硬件,仅在原有控制程序中采用新的调速算法即可。

This paper introduces a method used in tri-speed single-phase motor to increase its speed stages. By time-shared switching on, the motor may have 24 stages of speed that will be good for energy saving. To achieve these, this method needs no additional hardware but a new program for speed adjusting.
