Abstract
A wheel motor provided with a reduction gear includes a stator fixed to a casing, a hollow cylindrical rotor supported by the casing through a bearing, an output flange supported by the casing through a double row angular ball bearing and attached to a wheel, and reduction gearing having an input gear wheel supported by the rotor and an output gear wheel supported by the output flange and disposed in a hollow in the rotor. The rotor has a thin-wall edge portion and a second, opposing edge portion. The thin edge portion and the opposing edge portion form two axially spaced points at which the rotor is rotatably supported by ball bearings.
