  • Arrangement for fastening permanent magnets to rapidly rotating rotors of electric machines
    Patent number: 7692348
    Abstract: The invention is directed to an arrangement for fastening permanent magnets to rapidly rotating rotors of electric machines. It is the object of the invention to find a novel possibility for fastening permanent magnets to the rotor of rapidly rotating electric machines which allows the magnets to be fixed so as to be secure against centrifugal forces for high rotating speeds and under confined spatial conditions without a frictionally engaging connection of magnet holders to the rotor.
    Type: Grant
