Abstract

A rotor of an electric rotating machine, more particularly an axial flux machine, and an electric rotating machine equipped therewith. The rotor of the electric rotating machine, more particularly an axial flux machine, includes a plurality of magnets and a magnet carrier for fixing the magnets, with which carrier the magnets are positioned on a periphery with respect to a hub of the rotor. The magnet carrier extends radially outwards further than the magnets and has a first axial width at the periphery of the positioning of the magnets and forms a widened portion radially outside the magnets which has a second axial width which is greater than the first axial width. Using the rotor proposed here and the electric rotating machine equipped therewith, devices can be provided which, in a simple and cost-effective manner, guarantee efficient and low-wear operation.
