| Abstract: | Sensorless and brushless DC motor used for auto door features small size, weightless, efficient and credible instead of AC motor. We used ATmega16 SCM as the control center in hardware and software systerns, and control principle, detection principle of the B - EFT are analyzed in this paper. This paper give a simple circuit for detection zero - crossing of the B - EFT. |
