Abstract
An electronically commutated brushless motor including a housing for accurately angularly aligning a position sensor relative to a position of a stator. The housing includes an integrally formed bridge for precisely situating the position sensor within the bridge, and a plurality of integrally formed locating ribs formed on an internal surface of a circumferential wall portion of the housing for precisely angularly situating the stator within the housing. Since the locating ribs and the bridge are all integrally formed on the housing, this eliminates the possibility of angular misalignment of the position sensor relative the stator during assembly of the motor.
