Abstract
Disclosed herein is a motor position and velocity detecting system capable of accurately detecting a position and a velocity of a motor without adding a hall sensor or the number of poles of the motor. The motor position and velocity detecting system includes: a hall sensor outputting hall signals from rotation of a motor; an edge detector detecting edge signals for the hall signals to output edge pulse signals; a peak detector detecting peak signals for the hall signals to output peak pulse signals; a position outputter connected to the edge detector and the peak detector and outputting a position of the motor; and a velocity outputter connected to the edge detector and the peak detector and outputting a velocity of the motor.
