Design of Brushless DC Motor’s Control System Based on LS052A-Cb

Abstract.The permanent-magnet brushless DC motor (BLDCM) has achieved a brilliant application in household equipment industries, since it has specific advantages. The cost control has become a main problem, on the low-end of the market whose customers were more sensitive to the price. To this a low-cost brushless DC motor control scheme based LS052A-Cb microprocessor is presented in this paper. This article introduce the hardware and software design scheme of the BLDCM’s controller and implement space vector pulse width modulation (SVPWM). After verification, the program can ensure that the system is stable and reliable at low cost.
