Abstract: The vibration motor comprises adjoining working and feed-back piezoelectric cells, one of which is in contact with one of the stages of a concentrator of ultrasonic vibrations, whose other stage is pressed to one of the rotor surfaces. The working piezoelectric cell is connected with the output of an electric oscillator, the feed-back piezoelectric cell is coupled to the oscillator sync input. Provision is made in the vibration motor for a means for rotation frequency control of the rotor by changing the hold-down force pressing the driving stage of the concentrator of ultrasonic vibrations to the rotor surface and/or by maintaining the amplitude of ultrasonic vibrations of the driving stage of the concentrator at a preset level, or by varying the hold-down force of the driving stage of the concentrator of ultrasonic vibrations alongside with changing the amplitude of ultrasonic vibrations of the concentrator driving stage.
