摘要
目前卷绕物放卷张力控制元件一般采用磁粉制动器,动态性能欠佳且工作于耗能型制动方式,为降低此类设备的耗电量,进一步提高张力控制性能以满足高速生产的要求,提出一种运行于力矩控制方式的印制绕组直流伺服电机式放卷张力控制系统,该系统能将电机制动能量回馈给电网以达到节能的目的。介绍了该系统的组成原理与设计方法,以及能适应于卷径大范围变化的张力自整定控制方法,并简介了系统实现技术,该系统具有很好的应用前景。
Current unwinding tension control systems generally use magnetic powder brake, which has poor dynamic performance and is belonged to energy-consuming type of brake. In order to reduce the energy-con- sumption of these devices and further improve the control capability to meet the requirements of high-speed production, a unwinding tension control system which runs in torque-controlling method and use DC servo motor as its＇ executant was proposed. The system is able to feedback the brake energy to power grids. System＇s principle, design method and tension control for wide range variation of web radius were introduced. Realizing technologies were simply introduced. The system has good application prospects.
