<p>Permanent-magnet electric machine comprising a stator and a rotor, wherein the stator has a coil arrangement and the rotor is provided with permanent magnet elements, an air gap is formed between the stator and the rotor, which air gap is delimited by the permanent magnet elements and with magnetically conductive teeth of the stator which are aligned in specific positions with said permanent magnet elements, wherein the rotor has a rotor bell, which has a plurality of layers of resin-fibre composite material, is an integral body having a rotor tube and a rotor base and has at least one filament bundle in the region of the rotor base, wherein the at least one filament bundle reaches from the centre of the rotor base substantially along imaginary radii or secants over the outer rim of the rotor base and is bent back at the outer rim of the rotor base and merges, uninterrupted, with the rotor tube in the axial direction and/or at an angle with respect to the mid-longitudinal axis of the rotor tube up to the free peripheral region thereof.</p> |
