PIEZOELECTRIC WAVE ENGINE Russian patent published in 2006 - IPC H02N2/00 

FIELD: electric engineering, possible use in laboratory devices, robot engineering, machine-tool industry, optical electronics, mechanics.

SUBSTANCE: engine contains body, one or two piezoelectric oscillators, at least one rotor and wave guide, made in form of metallic rod; while oscillators are connected to ends of wave duct rod, which can have at least one curvilinear portion, upon which a rotor may be positioned, made in form of a ring. At certain frequency of oscillator oscillations, rotation of rotor, touching surface of wave guide, occurs.

EFFECT: simplified construction, expanded functional capabilities.
