Abstract

The invention's goal is to develop a piezoelectric motor delivering high output torque, speed, and operational stability under high loads. Comprising an elastic ring-shaped stator (6) with trapezoidal teeth (7) on either side, cuts (8) align along the teeth's horizontal axis of symmetry. Piezoelectric elements (9) are interspersed between the teeth (7). The upper and lower dual-sided trapezoidal teeth (7) are pressed against disk-shaped rotors (2) via rigid friction elements (10) positioned between them. Rotors spin as electric harmonic signals, matching the longitudinal vibration resonance frequency of the ring (6), energize the elements (9). Dual harmonic signals require a phase difference of π/2. A single electric signal activates one of the element groups (18, 19), leaving the other passive. Shifting from harmonic to sawtooth or rectangular waveforms, and combining elements (18, 19) into a unified group, establishes the inertial operating principle.
