Abstract：Aiming at improving the efficiency and the speed regulating characteristic of fans used in factories， mines and cars， a control system of brushless DC fan based on dsPIC30F4012 which was made by microchip company was investigated and implemented. Hardware system with high reliability was firstly elaborated. Then， the software and the control algorithm were introduced. The system was evaluated by experiments and some conclusions were given. Experiment results show that the system has fine speed regulation performance and high reliability.
Key words：brushless DC motor; fan; DSPIC30F4012; integral separation PID algorithm
