基于LM3108K的交流电动机软启停实验系统设计

Design of Soft Start-brake Experiment System for AC Motors Based on LM3108K

采用和利时LM小型PLC LM3108K为核心,对实验室环境中小功率三相交流电动机提出电压斜坡软启停实验系统。该实验系统配有磁粉制动器作为可调负载,结合智能三相调压模块调压输出,能够对小功率三相交流电动机软启动和软停车进行实验控制演示,实验效果良好。

LM PLC-LM3108K was used as core device for a ramp voltage soft start-brake experiment system of low power AC motors in lab. The experimental system was equipped with magnetic powder brake as an adjustable load. Combined with the output of intelligent three-phase voltage regulating module, it can demonstrate the experimental control of soft start and soft stop of low-power three-phase AC motor. The experimental results are good.
