This paper presents a novel rotor position detection method for Brushless DC motors using AC Component of Supposing Neutral Point (SNP). SNP voltage was analyzed.And zero-crossing detection of integrated AC component gave commutation instants. This method also worked for the BLDC without ideal trapezoidal magnetic field over a wide speed range and was simple to implement. It provided especially good performance for low voltage BLDC.The validity is verified through experiments.
