Abstract:A control system for BLDCM applied in industrial sewing machines was designed in this paper.In the control strategy，the system adopted integral separate PID to improve its energy efficiency and the control effect.At the same time，a new position parking method was presented；the method made use of Z-pulse characteristics of photoelectric encoder and eliminates the position sensors in the conventional system.Improving the positioning procedure，gained the more precise position.Finally，the simulation experimental prototype results show that this system can starts fast，operates stable，and positioning control is very accurate.
