Application of linear motors in electronic jacquard

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 concentratively.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.
