Analysis and Optimization of Needle Selecting Electromagnet for Computer Jacquard Circular Knitting Machine

The efficiency and productivity of the circular knitting machine are affected by needle selecting electromagnet. Formula experience method and finite element analysis method are used to optimize the scheme. The electromagnetic force and dynamic response characteristics of the electromagnet are improved obviously. Ansoftmaxwell software was used to analyze the core diameter, permanent magnet width and exciter coil height, and the determined values were obtained. The dynamic response test of the optimized scheme shows that the whole system works stably and the knitting efficiency is also improved, which has reference significance for improving the quality of domestic needle selecting electromagnet.
