Title:
圧電超音波モーター
Document Type and Number:
Japanese Patent JP4620115
Kind Code:
B2
Abstract:
The invention relates to a piezoelectric ultrasound motor with an oscillator in the form of a piezoelectric plate of the length L and the height H as well as with one or two friction elements which are arranged at the oscillator and elastically pressed against the friction surface of the part to be moved. According to the invention, the piezoelectric plate is divided into two identical parts by a section plane extending vertically to the large surfaces, with at least one of these parts including an asymmetrical generator of an asymmetrical acoustic standing wave, which upon its activation generates an asymmetrical two-dimensional standing wave, so that the friction elements which are arranged in the center of the long end face of the plate carry out a movement with an inclination relative to the end face, so that the energy of motion is transferred to the element to be moved.
