ABSTRACT:
Apparatus for controlling phase commutation of a brushless DC motor. The apparatus is comprised of a back EMF detection technique to determine the current position of the rotor, an error rejection circuit to prohibit commutation noise from causing errors in determining the present rotor position, a means for determining the next phase set to energize and proper energization timing to maintain a lead angle between the physical rotor position and the magnetic wave, and a means for driving the appropriate brushless DC motor phases with current.
