A speed control system of small DC motor used in model car is introduced. The system has a control unit of the single-chip MC9S12DG128B, using PWM control signal, using H-bridge on the principle to control RS380-ST motor, and H-mode bipolar converter circuit is composed of boost circuit MC34063 and Mosfet IRF3703. Freescale CodeWarrior 4.7 is used as software development enviro-ment, and the kernel codes are given. Controls of motor, such as start, running, reverse, brake and stop is achieved by this system. The speed control system is characterized by strong practicality, high performance-price ratio, simple structure and low power dissipation.
