Abstract: Brushless direct current motor(BLDCM)is a very promising electronic control motor, which is used widely in various fields. In a BLDCM control system, a microcontroller unit(MCU)plays a significant role as a main control chip. The category and function of timers in CKS MCU are introduced. Then a design on pulse width modulation (PWM) of advanced timers is proposed. A typical BLDCM control system is present in this paper. At last, this application is implemented at the core of CKS32F030C8T6.

Key words: brushlessdirectcurrentmotor, MCU, timer, PWM
