织针直驱直线电机技术研究进展与挑战OA

The linear motor technology for direct driving knitting needle is able to improve production efficiency of conventional knitting processes by an order of magnitude,and has the potential to achieve three-dimension fabrics weaving in the future.In a long time,because of the dual challenges of technical difficulty and economic cost,it's obscure in the research demand of direct knitting linear motor,and corresponding technology develops very slowly.This paper starts from the fundamental performance specifications of knitting machine and makes the research demand clear.Three key technologies are summarized,including ultra-thin linear motor design,multi-physics field coupling in ultra-thin linear motor martrix,and multi-degree-of-freedom motor matrix.Comprehensive domestic and foreign researches are reviewed,and the research progress of electric knitting needle design is made clear in detail.Current challenges and corresponding countermeasures are put forward regarding structural failure mechanism that arises from multi-physics field coupling inside linear motor matrix,which positively responds the ergent era development question of tradition textile industry.
