  • Regulated permanent magnet generator
    Patent number: 6455975
    Abstract: A regulated permanent magnet generator incorporating a “tapered” or conical design for improved voltage regulation. The tapered faces of the rotor and stator are axially displaced from one another as the demand for voltage changes. In addition, this design allows for the stator and rotor to be used as a braking mechanism when placed into frictional contact with one another such as to prevent windmilling. This design offers better space efficiency when used with certain engine applications.
