直线电机在电子提花机中的应用

Application of linear motors in electronic jacquard

为简化电子提花机的结构,提出用直线电机驱动的设计方案。直线直流电机经过材料和结构的改进,代替电磁阀驱动机构。该系统采用双向可逆的驱动电路,用驱动电流变化来控制直线电机的运动。程序设计中,用状态位"P"来表示电机的位置,通过判断前后2个相邻的状态,将往复运动改成单程运动。整体结构上,直线电机和传感器采用集中安装和控制的方式。与传统的电子提花机相比,直线电机驱动的提花机结构更加简单,控制目标非常明确。驱动系统应用于实际生产中,能加快提花机的运行速度,提高工作效率。

In order to simplify the configuration of electronic jacquard, a method of linear motor drive was presented. Through the improvement of material and structure, the electromagnetic drive was replaced by linear DC motor. The drive circuit was reversible in this system. The linear motor was controlled by the change of drive current. There was a bit ＂P＂ to represent the location of the motor in the program. Advance and return movement was replaced by unidirectional motion judging the adjacent state of the bit ＂P＂. The motors and sensor were installed and controlled coneentratively. The configuration is simpler and the control objective is much obvious in the electronic jacquard driven by linear motor when compared with traditional one. It can speed up the running of the machine and improve the work efficiency to apply this system in practical production.
