| Abstract: | Back-EMF method is used to control BLDCM.It can realize sensor-free control method by detecting the zero point of EMF.A new zero-crossing detection circuit is designed in this system,compared to the previous method is more simple and reliable,including software flow chart and designed circuits.Finally the experimental result shows those works are effectual. |
