Abstract:
An electronically commutated brushless motor comprising:a housing having a circumferential internal wall and an end wall formed near a proximal end of said housing such that said internal wall extends proximally past said end wall, said housing being closed at a distal end by a first end cap and closed at the proximal end by a second end cap; at least one position sensor for sensing a position of a rotor of said motor during operation of said motor; a bridge integrally formed with said end wall, said internal wall surrounding said bridge, said bridge having a generally hollow, distally facing interior area, said bridge configured to substantially enclose and precisely support said position sensor within said interior area; a plurality of locating ribs integrally formed on said internal wall of said housing and configured to precisely situate a stator; and wherein said locating ribs and said bridge, both being integrally formed on said housing, eliminate the possibility of misalignment of said position sensor relative to said stator during assembly of said motor.
