  • Continuous transformer and motor
    Patent number: 4827097
    Abstract: A combined transformer and motor having a continuously energized primary winding producing a continuous output voltage from a transformer winding and a selectively enabled motor shaft rotational output which is selectively actuated by powering a further primary winding.
    Type: Grant
    Filed: May 7, 1986
    Date of Patent: May 2, 1989
    Assignee: Litton Systems, Inc.
    Inventor: Jeffrey K. Cornell
  • Compensation for improved continuous transformer and motor
    Patent number: 4812607
    Abstract: A combined transformer and motor is disclosed having a continuously energized primary winding producing a continuous output voltage from a transformer winding and a selectively enabled motor shaft rotational output which is selectively actuated by powering a further winding, along with compensation means to stabilize the continuous output voltage in view of the selective actuation of the further winding.
    Type: Grant
    Filed: September 2, 1987
    Date of Patent: March 14, 1989
    Assignee: Microwave Products of America, Inc.

  • Flux reduction compensation for continuous transformer and motor
    Patent number: 4801776
    Abstract: A combined transformer and motor having a continuously energized primary winding producing a continuous output voltage from a transformer winding and a selectively enabled motor shaft rotational output which is selectively actuated by powering a further primary winding, and further having a reduced cross section area in the flux conducting structure of the combined transformer and motor for improving the regulation of the output voltage.
