Abstract
The rotor of the outer-rotor type wheel-in motor of the electric wheel includes a field generator facing the outer surface of the stator across from an electrical gap. The field generator includes pole magnets magnetized in the radial direction with respect to the rotation axis of the wheel-in motor, adjacent two of the pole magnets having opposite directions of magnetization so that magnet polarity of the field generator alternates at a predetermined pole pitch along the circumferential direction, yoke magnets magnetized in the circumferential direction each of which is put between corresponding adjacent two of the pole magnets to strengthen magnetic field formed by the pole magnets, and a field generator support member to which the field generator is fixed, the field generator support member being fixed to the rotary shaft which is rotatably supported by a wheel suspension system of a vehicle.
