Abstract
An axial flux electric motor is disclosed. The motor includes a rotor having a first rotor face, a second rotor face, a primary bearing locator on the first rotor face and one or more permanent magnets mounted to the first rotor face. Also included is a stator having a first stator face, a second stator face, a secondary bearing locator on the first stator face, a stator winding having one or more conductors and a connector for connection of the stator winding to a power source. A bearing assembly is also provided and positioned between the first face of the rotor and the first face of the stator for rotationally supporting movement of the rotor relative to the stator, the bearing assembly axially displacing the rotor from the stator to provide an air gap therebetween. The bearing assembly is engaged by the primary and secondary bearing locators to correctly position the bearing assembly.
