Optimal Design and Study of Positive and Negative Rotation Control of Motor

电动机正反转控制在工程应用中具有重要的意义。对电动机各种状态进行了研究,绘制状态切换流程图,利用经验设计法设计步骤,借助保持指令、辅助继电器和定时器,通过三菱编程软件GX Developer-8.34,设计了PLC梯形图,借助仿真软件GX Simulator6-C模拟表明:程序实现了电动机在任意状态下自由切换的功能,并通过实际操作发现,程序方便使用,验证了程序的可行性。经验控制程序运行步数仅36步,与顺序控制程序相比步数少200%,程序自由转换功能使停止按钮使用次数大大降低,从而验证了程序的实用性。研究成果对电动机的工业应用提供了借鉴意义。

The positive and negative rotation control of motor is of great significance in the engineering application. The state switching flow chart was drawn by means of the analysis of various states. Based on the design steps of empirical design method, by means of hold instructions and aided relays, the PLC ladder diagram was given based on the program of GX Developer-8.34. Through Mitsubishi software simulation, results show that this program can implement motor switching freely in any state, the program is very convenient and feasible by operation, which indicates the program is available. Compared with sequential control program, this program＇ s step number less 200%. Switch free could reduce the frequency of operating stop button, which proves the practicability of the program. The result provides reference for the engineering application of motor.
