Method for manufacturing a rotationally symmetric, metallic composite body and outer rotor for wheel motor manufactured by this method

摘要

The manufacturing method uses an outer metallic ring (12), e.g. of steel, provided with grooves (16) parallel to its longitudinal axis on its inside surface (14), filled with an electrically and./or thermally conductive inner layer of a non-ferrous metal, e.g. Cu, provided by spaced bars of an integral component which extend between solid rings at either end. An Independent claim for an external rotor for a wheel motor is also included.
