  • Patent number: 5780956
    Abstract: A piezoelectric drive to provide a rotary force to a rotating element includes a pair of circumferentially spaced fingers. The fingers are selectively moved towards and away from the rotating element with piezoelectric actuators that expand and contract. An intermediate piezoelectric actuator moves the two fingers away from each other or allows them to be moved towards each other. A bias force acts in opposition to the intermediate piezoelectric actuator. By controlling the three piezoelectric actuators, the system rotates the rotating element. The system is preferably utilized for driving a vehicle component, and most preferably, a window for a vehicle. The inventive motor provides a low cost compact motor for driving vehicle components.
