According to the degree of automation of mechanical drive industrial sewing machine parts of the low, slow response speed, transmission mechanism between the gear accuracy and weak synchronization, mechanical shaft is easy to appear the mechanical resonance, noise and so on, this article will use the 3 motor independent control of three motor units, industrial sewing machine. The motor control system with single takes DSP as the control chip and related peripheral circuit composed of three closed loop DC speed control system (speed loop, current loop, position loop). Experimental results show that the motor control system can achieve good dynamic performance and wide speed range, and the system has the advantages of simple structure, speed error within 2%, reliable operation, and has high use value.
