Abstract: In this paper, according to the characteristics of the power needs of nasosinusitis operation process, was designed based on the DSPIC6015 chip and the control of BLDC and DC motor control system. BLDC can realize the functions of positive rotation, reverse, swing, positioning, stop, speed regulation and memory; brush DC motor can realize two speed control, and the driving system of hardware, software, structure design. Particular requirements for safety driving system according to the operation knife, the overall design considerations of EMC and protection. The contrast experiment with the similar products abroad in this design, the design of the product has technical and price advantage, so it has strong competitive.
