ABSTRACT:
The vibration motor of the invention comprises a concentrator of torsional vibrations including at least two stages. The first one of the stages takes up vibrations from a piezoelectric cell while the second stage contacts a rotor. The concentrator is provided with means for transforming piezoelectric cell vibrations into torsional ones, said means being fashioned as rods provided on the side surface of the first stage. The rods are located in a plane normal to the concentrator axis and inclined each at an acute angle to a tangent at the point where the rod is attached to the line of intersection of the side surface of the first stage with said plane. The rods serve as resonators of longitudinal vibrations propagating therein.
