Abstract

FIELD: automatic-control and follow-up systems. SUBSTANCE: motor has rotor and stator positioned coaxially, at least one oscillator in the form of circular piezoelectric element with electrodes and polarization providing for excitation of radial oscillations. Motor also has flexible plates-pushers pressed with one end to side surface of rotor. Oscillator has metal washer which is pressed to face surface of at least one piezoelectric element through film of sound insulating material by means of threaded connection insulated acoustically from piezoelectric element and washer. Pushers are secured to cylindrical surface of washer. EFFECT: increased maximum permissible power of motor. 5 dwg
