Patent ID: 8476794

Claim:
An in-wheel motor comprising: an inner stationary stator including a plurality of magnets comprised of a plurality of windings, the magnets arranged at an outer circumference thereof; an outer rotor surrounding the inner stationary stator and including a plurality of rotor magnets arranged circumferentially thereon; a bearing layer positioned between the inner stationary stator and the outer rotor and configured to allow rotational movement of the outer rotor relative to the inner stationary stator, and further configured to distribute forces applied to the outer rotor; a plurality of switches, each switch arranged correspondingly to a winding of the plurality of windings; and a controller configured to apply a switching pattern to the plurality of switches to cause the outer rotor to rotate, wherein the switching pattern comprises substantially simultaneously energizing of two opposite windings of the plurality of windings, wherein the two opposite windings are positioned on opposite sides of an axis about which the outer rotor is configured to rotate.
