  • Series redundant drive system
    Patent number: 3950686
    Abstract: Disclosed is a plurality of motors mechanically connected in series so as to provide operational redundancy. The shaft of a given motor is rigidly attached to the housing of the next motor in the series, so that rotation of the first shaft will cause the second motor and its shaft to rotate. Means are provided to prevent relative rotation of the rotors of the redundant motor(s). Other means are provided to detect failure of the operating motor and to activate another motor in the series when this occurs.
