基于和利时PLC的交流电机运行参数监测实验系统设计

Design of Working Parameters Monitor Experiment System for AC Motors Based on HollySys PLC

提出了基于和利时LM小型PLC的实验室环境下的小功率交流电动机运行参数监测实验系统。在自制和利时PLC实验台的基础上,实现了分别以LM3108K为核心和以LM3107/LM3317为核心的两种实验设计方案。能够对小功率交流电动机的三相相电压、相电流、功率因数、有功功率、运行转速进行实时测量,具有一定的参考借鉴意义。

In this article,a working parameters monitor experiment system for low power AC motors in lab based on Holly Sys LM PLC is provided.This experiment system based on DIY Holly Sys PLC experiment platform,accomplishes two different experiment projects with LM3108 K and LM3107/LM3317 as core control unit respectively. This experiment system is able to measure parameters of low power AC motor such as phase voltages,phase currents,power factor,power and speed,which is a reference for others.
