  • Electronic braking device for asynchronous motors
    Patent number: 5376867
    Abstract: An electronic braking device is provided for an asynchronous motor equipped with magnetic bearings of a type used in turbomolecular pumps. The device comprises a circuit for recovering the kinetic energy of the rotor as it decelerates as a result of a disruption of electric current from an external power means. The device is adapted to convert the rotational kinetic energy of the rotor to an electric current and in order to maintain the support provided by the magnetic bearings.
