Influencing factors on high speed of electronic shogging system in warp knitting machines

The high-speed response of electronic shogging system in high-speed warp knitting machines is generally poor.According to the motion requirements of warp knitting machine guide bar,this research built a set of test platforms for the response of guide bar motion.Parameters such as servo inertia ratio,motor selection(such as motor power,magnetic pole pairs,and so on)of the electronic shogging system were experimented on to analyze the actual motion curve of the shogging servo motor and the control system command curve against the parameter variations.The experimental results show that the servo inertia ratio parameter setting of the electronic traverse system should be consistent with the actual load,otherwise it will cause comb bar oscillation during traverse,or insufficient motion rigidity,affecting the traverse accuracy.The selection of servo motor should consider the number of pole pairs and the motor power.Increasing the number of pole pairs of the servo motor can greatly improve the responsiveness of the system,and increasing the power of the motor does not contribute to the improvement of system responsiveness.
