The invention relates to vibration engineering and can be used in the development of precision vibration motors.

The purpose of the invention is to improve the uniformity of movement and accuracy of positioning.

FIG. 1 shows the structure of the device; in fig. 2 illustrates embodiments of a motion parameter converter (vibration).

When transmitting torsional vibrations through the string 8 and tu 10 due to the displacement of the clamp 11 in the string, oscillations are generated either at the fundamental frequency corresponding to the natural frequency of the string segment from the output shaft to the clamp location And, or a multiple of the higher frequency, i.e. . The control of the frequency and phase of oscillations is provided, which also leads to an increase in the equalization of the vibration motor (Fig. 1 and 2), contains the dimensionality of rotation of the device shaft and the torsional oscillator 1, controlled by a mechanical power amplifier 2 TI with a power input shaft 3 and a kinematic connection, which can be endured positioning.
