  • Ultrasonic motor and drive device
    Patent number: 10985674
    Abstract: The invention relates to an ultrasonic motor comprising a plate-shaped piezoelectric ultrasonic actuator (2) and a of friction element (5) arranged on a side surface thereof, wherein the connection line (V) through the friction point and the focal point (S) of the ultrasonic actuator defines an operating direction, and a perpendicular plane intersecting the ultrasonic actuator defines an operating plane (W). A holder (6) has two force inlet sections (7) in order to move the holder and thereby the ultrasonic actuator in a direction parallel to the operating direction, and to press same against an element to be driven. The force inlet sections, preferably based on permanent magnets (8, 9) are each arranged in the operating plane and laterally next to and at a distance from the the ultrasonic actuator, and the intersection point (SP) of the connection line (V) with the operating plane (W) either coincides with the focal point (S) or lies between the focal point and the side surface having the friction element.
