Study on magnetic suspension-type Needle Driving Model for a New Knitting Device

Based on the magnetic suspension theory, this paper has proposed a kind of suspension-type jacquard needle driving principle, and designed its 3-dimension model method. By making finite element analysis on suspension-type needles, analyzing the experimental data and designing the structure, we can get the relationship among related parameters under conditions of different permanent-magnet thickness and air gaps, which can provide criteria in theory and application for designing on new needle driving principle, control system and needle.
