摘要： The invention relates to an annular or hollow cylindrical ultrasonic actuator, on the end faces of which are arranged n≥2 friction elements, and on the outer peripheral surface of which are arranged 2n excitation electrodes, spaced apart from one another in each case by a separating gap, each of the friction elements being arranged in the region of a separating gap, wherein, between friction elements that are adjacent with respect to the periphery of the ultrasonic actuator and are located on different end faces, two excitation electrodes are arranged such that, when the ultrasonic actuator is electrically excited, the friction elements of both end faces simultaneously perform a movement which is suitable for driving an element to be driven to rotate in the same direction. The invention further relates to an ultrasonic motor having an ultrasonic actuator of this kind and having a holding device in which the ultrasonic actuator is inserted.

摘要： The present disclosure relates to a linear drive, including: an actuator unit with at least one actuator; two guide elements and a movement element, wherein the movement element is displaceable along both guide elements by a movement generated by the actuator unit as a result of a stick-slip effect. In order to allow a more accurate displacement of the movement element in a compact design of the linear drive, the movement element can be brought into engagement with each of the two guide elements by static friction in order to be displaced along the two guide elements as a result of the stick-slip effect.
