Abstract: This paper designed a novel needle selecting device for the electronic jacquard loom utilizing the piezoelectric effect of the ceramics bimorph and elucidated its working principle. The ceramics bimorph is characterized by high anti-interference to the electric current, low heat generation, no harmful vibration in the transition process when the electric current has a sudden change, no interference phenomenon of electromagnetism, remaining stable and low error rate at high speed operating of the loom. So, its use facilitates to further raise the jacquard speed and reduce power consumption. The photograph of high speed image system shows the moving process of the main hooks, and analysis of one cycle of the movement on the picture indicates that their movements are precision. The experiment results demonstrate that this needle selecting device for the electronic jacquard loom runs very well.
