Abstract: Brushless DC motor drive system based on DSP in the HVC was researched by digital control manner in the paper. Integrating electromotor and generator, a rare earth permanent magnet brushless direct current motor (REPM BLDCM) control system based on DSP in the HVC was studied. TMS320LF2407A was chosen as main control chip in this system. The structure peculiarity, design method and control method of this control system were introduced. It is showed that the design is rational by prototype trial of a brushless DC motor.
