Abstract: A double-rotor single stator axial flux machine, which is supplied having no bearings between the rotors and stator internal of the machine, is mounted to an external structure such as an interface of an engine of a vehicle or a portion of the transmission of a vehicle. The machine is mounted to the structure via the shaft of the machine (on which are seated bearings located in the structure) and the stator housing. The bearings of the structure, which are external to the machine, permit the rotors to rotate relative to the stator when the machine is installed on the structure.

Abstract: A brushless motor includes a stator having stator core and winding teeth evenly distributed on the stator core; and a rotor rotatably disposed within the stator with the winding teeth facing the rotor, where the rotor has a rotor core and magnets evenly distributed around the rotor core. A first symmetry axis is defined passing through a center of a one of the magnets to a center of the rotor, and a second symmetry axis is defined passing between adjacent magnets to the center of the rotor. A first distance between the outer surface of the rotor to a surface of a winding tooth when the first axis is aligned with the winding tooth is smaller than a second distance between the outer surface of the rotor to the surface of the winding tooth when the second axis is aligned with the winding tooth.
