摘要:
The invention relates to an ultrasonic motor having a multilayer actuator in the form of a multilayer plate, having one or more friction elements or friction layers on its side surfaces and having an electrical exciter apparatus for the actuator. According to the invention, the multilayer plate has two intersecting, mirror-imaged asymmetrical generators for ultrasonic vibrations, to be precise in the form of layers of exciter electrodes and general electrodes which are alternately arranged with layers of piezoelectric ceramic, wherein a two-dimensional asymmetrical acoustic standing wave is generated in the multilayer actuator.
