| Abstract: | A novel brushless DC motor control system based on C868 without position sensors was presented.The brushless DC motor sensorless control solution with the onchip capture/compare unit CAPCOM6E was given.According to the open circuit stator winding back EMF crossing zero,the rotor position was calculated with filtering algorithms,while the position sensors were no longer needed.The power module CPV362M4F was used to improve the system reliability while restricting the system size. |
