An electric generator comprises: a housing; a stator disposed fixedly relative to this housing and having a number of pole-forming ferromagnetic cores ordered in a circle, around which are arranged respective windings of insulated, electrically conductive wires; a rotor mounted rotatably relative to the housing and comprising a number of magnets arranged in a circle, and has the characteristic that the magnets are supported by a metal first ring which is supported by a second ring consisting of cured plastic reinforced with fibres, which rings are arranged in a housing; the field in the magnets has a direction corresponding to the axial direction of the rotor; the cores extend in axial direction of the rotor; and the cores and the associated windings are embedded in cured plastic reinforced with fibres, and form with this fibre-reinforced plastic a closed round structure with a central zone substantially consisting of only reinforced plastic. |
