摘要
分析了三相异步电动机变频调速的原理,建立了以AB Micro850 PLC和PowerFlex525变频器为控制核心的双电机同步控制系统,介绍了系统主要的软硬件设计流程。对控制系统进行了实验研究,通过分析双电机运动曲线得出研究结果,表明该系统性能良好,适用于于双电机的变频调速控制场合。
In the paper, the principle how to regulate the speed of three-phase asynchronous motor by frequency conversion is analyzed. The synchronous control system of double motor is mainly composed of AB Micro850 PLC and PowerFlex 525 transducers. The composition of hardware and the design of software were discussed. .After the experiment testing the system, the result reached from the speed curve analysis, demonstrate the high performance of the system, which can be applied to double motor control.
