A leadless motor rotation detector apparatus for determining the direction o f shaft rotation of a motor, the motor of the type providing a fluctuating magnetic field whe n rotating, the apparatus having at least two sensors separated a predetermined distance D1 from one another, each sensor operable for sensing the magnetic field and generating a corresponding signal having an amplitude and phase associated with the sense d magnetic field; and a processor responsive to the signals for comparing temporal aspects associated with the relative phase of each of the signals to determine a leading signal , the leading signal associated with a corresponding one of the at least two sensors and i s indicative of the direction of motor rotation.
