Abstract: In order to improve the performance of electronic Dobby, determine the influence of the electromagnet working state on 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 analyzed and researched by experiments. And the working situations of a imported and a domestic electromagnets were compared. The results show that all these parameters have some influences to it. So during the production, processing and using the electromagnets, we have to improve machining precision, take some shielding measures between multiple electromagnets, provide a stable and reliable power and appropriate environment.

Key words: electronic dobby, electromagnet, swing arm, dynamic performance
