ABSTRACT:
An integral field and commutation magnet for use in DC brushless motor has both commutation and field magnet portions. Magnetized segments in both the field and commutation portions have oppositely oriented magnetic fields in the outward radial direction. An apparatus and method for making the one piece integral field and commutation magnet employ a fixture with a current conductor associated with magnetic flux paths corresponding to the segments of the commutation and field magnet portions to magnetize a single piece of permanently magnetizable material.
