Abstract (en)

[origin: WO2004057737A1] The invention relates to a rotor for an electric motor, especially a line-start electric motor, comprising axially extending receiving regions (4-6) for conductive rods, and axially extending receiving regions (10, 11) for permanent magnets (14, 15) which are embodied and arranged in such a way that they produce a permanent magnet field with a magnetic axis (22) and a neutral axis (23). The aim of the invention is to ensure that the rotor runs as regularly as possible during the operation of the electric motor. To this end, the diameter of the rotor along the magnetic axis (22) is larger than that along the neutral axis (23).
