用单片机变频器控制电动机调速实验的探索

Quest for the Experiment of Controlling Electromotor Timing with Single-Chip Computer Transducer

介绍了用MCS-51系列单片机控制变频器实现对三相异步电动机开环调速和闭环调速的三种不同控制方式的实验电路的实验原理,并给出几种抗干扰措施的抗干扰效果演示实验,这些实验接近工程实际,有较好的教学效果。

This article introduced the principles of the experimental circuits for three different controlling mode of controlling the transducer for implementing the open-loop and closed-loop timing of a triphase asynchronous electromotor with single-chip computer of MCS-51 series, and the demo experiments for the anti-jamming effects of several anti-jamming measures. These experiments are close to the engineering conditions, and have quite good teaching effects.
