| 摘要 |
The invention relates to a motor which converts the ultrasonic-range mechanical vibrations into mechanical energy used to drive two rotors into a continuous rotation motion, with the possibility of speed control. According to the invention, the motor consists of two rotors (), each of them being placed on one of some shafts () positioned on a quasi-diametral direction on either side of a system consisting of a coupling of two piezometallic discs () attached to each other, each of them being separately supplied from one of two ultrasonic frequency sources () and supported by means of a device () at a certain distance () from the center of the first above-mentioned disc (), the two discs () being attached to each other at a distance () between their centers and vibrating under the action of adjustable frequency or phase shift supply signals. |
