Abstract

A motor is provided including a motor housing having an open end; a stator disposed within the motor housing and including a stator core, stator windings, and an end insulator that electrically insulate the stator core from the stator windings and includes an annular body; a rotor rotatably received within the stator and including a rotor shaft extending along a longitudinal axis and permanent magnets; and a bearing bridge including a center pocket arranged to support a bearing of the rotor shaft. The bearing bridge is received at least partially within the end insulator. The annular body of the end insulator includes at least one peripheral opening located within the motor housing, and the bearing bridge is radially piloted relative to the motor housing via a retaining member received through the at least one peripheral opening.
