FIELD: electricity.
SUBSTANCE: generator comprises a thin-walled cylindrical piezoelectric cell fixed by its outer side to the inner surface of the body rotation and several symmetrical weights fixed to it from the inner side. When a body is rotated in regard to its longitudinal axis, the weights under centrifugal forces perform circular deformation of the piezoelectric cell that generates electric voltage.
EFFECT: reducing weight and dimensions and improving reliability and capacity of the piezoelectric current source.
