  • Rotor with permanent magnets forming a portion of a rotor core
    Patent number: 11362555
    Abstract: The disclosure relates to a rotor for an electrical machine having internal permanent magnets including a yoke consisting of a stack of sheets defining a plurality of recesses for receiving parallelepipedal permanent magnets, the recesses being surrounded by magnetically saturated external transverse isthmuses, by radial isthmuses, lateral isthmuses and oblique isthmuses, wherein the magnets are assembled in pairs of magnets magnetized in the same direction and perpendicular to the radial direction of the radial isthmuses arranged between the coupled magnets, the radial isthmuses having a thickness of less than 5% of the diameter of the rotor, and the perimeter of the cross section of the rotor is formed by a succession of curved profiles, between two consecutive pairs of magnets, and tangential linear profiles at the external transverse isthmuses. The disclosure also relates to the application of such a rotor for creating a motor, in particular a motor for a turbo compressor, or an electrical generator.
