Abstract

The sliding electromagnetic coupling is used in crankshaft control, dynamometer, starting and braking devices for the drive mechanisms of pumps, pumps, compressors, and fans. Electromagnetic clutch couplings solve the problem of silent starting, limiting torque, and remote control of clutch and engine disengagement, progressive variation of output shaft speed. The sliding electromagnetic coupling operation can occur at constant torque or at constant power. These regimens are obtained by the corresponding variation of the excitation current. The paper presents the operation and analysis of parameters in constant torque regime. The test bench contains three-phase electric drive, sliding electromagnetic coupler, sliding electromagnetic brake and PLC control part, frequency converter and HMI operator panel. The torque is measured using a weight sensor connected to an ARDUINO development board that supplies an analogue value in the 0-10V range for an analog input of the PLC. The results are shown on HMI device and the PLC programming is done in Siemens TIA Portal. The communication between sensor speed and PLC is realized by PROFIBUS-DP protocol.

PLC自动化系统中滑动电磁耦合参数分析

滑动电磁联轴器用于曲轴控制、测功机、泵、泵、压缩机、风机驱动机构的启动和制动装置。电磁离合器联轴器解决了静音起动、限转矩、离合器与发动机分离遥控、输出轴转速递进变化等问题。滑动电磁耦合工作可以在恒转矩或恒功率下进行。这些方案是由相应的励磁电流变化得到的。本文介绍了恒转矩工况下各参数的运行和分析。试验台由三相电驱动、滑动电磁耦合器、滑动电磁制动器及PLC控制部分、变频器和人机界面操作面板组成。使用连接到ARDUINO开发板的重量传感器测量扭矩，该开发板为PLC的模拟输入提供0-10V范围内的模拟值。结果显示在HMI设备上，PLC编程在西门子TIA Portal中完成。通过PROFIBUS-DP协议实现传感器转速与PLC之间的通信。
