变频器在纺丝摆频控制中的应用

Application of Inverters in Spinning Swing Frequency Control

为了防止纺丝卷绕在成形过程中丝层之间产生重叠、蹋边现象,要求卷绕设备上的槽筒电机具备摆频功能。本研究以美国罗克韦尔公司的Power Flex 40P变频器为例,结合其独特功能,通过对摆频控制上的应用进行研究,找到了一种简单可靠的摆频控制解决方案。

In order to prevent the overlap and edge damage between the layers in the process of spinning winding,it is required that the slot cylinder motor on the winding equipment should have the function of frequency swing.Taking the Power Flex 40P inverter of American company Rockwell as an example and based on the unique functions of the inverter,this paper finds a simple and reliable swing frequency control solution through the study of their application in the swing frequency control.
