Influence of electromagnet working state on dynamic performance of electronic dobby′s swing arm

In order to improve the performance of electromagnet for electronic dobby and determine the influence of the electromagnet working state on the dynamic performance of electronic dobby′s swing arm,the effects of the electromagnet′s working parameters,such as operating voltage,air gap width,operating temperature and bypass electromagnet′s working state,on the dynamic performance of electronic dobby′s swing arm were researched by experiments.And the working situations between the imported electromagnets and the domestic one were compared.The results showed that all these parameters have some influences on it.So during the production,processing and application of the electromagnets,machining precision should be improved,some shielding measures between multiple electromagnets are made,and a stable and reliable power and appropriate environment are provided.
