Abstract: A simple and easy to extend other functions brushless DC motor drive was designed, it can be used for a high-voltage and high-speed conditions. The MC33035 was combined with the microcontroller PIC18F1220 to solve the power supply problem on the bridge arm in the brushless DC motor driver which is caused by motor launch, because of the bootstrap capacitor technology was taken advantage of in the power supply. The other multiple functions, such as soft start, brake, reversion and so on, were also achieved in the brushless DC motor driver. Good performance of the system of stable and extensible was verified by the systematic experimental results. The system has some practical value in applications.
