摘要
采用西门子S7-1200型PLC作为控制器,Sinamics S120作为加载变频器,构建了基于PROFINET现场总线的两级控制系统,设计并实现了电机综合性能试验台的搭建。测试台能够完成三相异步电机、永磁同步无齿曳引机、永磁同步电机、变频电机等各类电机的精确加载试验。测试装置加载不仅动态控制精度高而且可靠稳定,采用伺服控制方式加载不需要进行转向识别,操作便捷。实际应用表明,该测试台控制精度能够达到预期目标。
In this paper,the comprehensive performance test bench of motor is designed adopting SIMATIC S7-1200 type controller,SINAMICS S120 and a two-level control system based on PROFINET fieldbus.The test platform can complete the type tests of threephase asynchronous motor,permanent magnet synchronous toothless traction motor,permanent magnet synchronous motor,frequency conversion motor and so on.The dynamic control system loaded by the test bench has high accuracy,reliability and stability,no need for steering identification,easy to handle.This paper introduces the design idea,hardware and software structure of the system and so on.The practical application shows that the control precision of the test bench can reach the expected target.
