The traditional needle driving in knitting machine has drawbacks,such as vibration,noise,temperature rising,high energy consumption,and so on.A new non-contact magnetic array needle driving method is proposed in principle,which completely overcome traditional mechanical cam driving shortcomings.The permanent magnet together with knitting needle as the permanent knitting needle,the control system real-time controls the electromagnet coil current direction and value,which can generate different magnetic force to drive the needle movement.The magnetic array needle driving structure and its DSP control system are designed,the mathematic model is analysed,and the experiment and simulation are applied.By comparing the experiment and simulation,the control system is verified to satisfy the new knitting needle driving.
