Abstract

В заявке описан пьезодвигатель, состоящий из соединенного с резонатором пьезоэлектрического конструктивного элемента (3) и из взаимодействующего с подвижным элементом двумерного резонатора (2), который имеет расположенные параллельно друг другу основные поверхности одинаковой формы и одинакового размера, при этом пьезоэлектрический конструктивный элемент не расположен в плоскости (8) симметрии резонатора. В заявке описан также способ изготовления подобных пьезодвигателей, резонаторы которых изготавливают из профилированного прессованного изделия путем их отрезания от этого прессованного изделия или из металлического листа постоянной толщины путем вырезания, предпочтительно путем вырубки, из него. Помимо этого в заявке описан способ возбуждения подобного пьезодвигателя, при осуществлении которого частоту или частоты возбуждения генерируют с помощью электронной системы управления на основе соответствующей величины возрастания тока и/или соответствующего минимального сдвига по фазе между током и напряжением и/или изменения сдвига по фазе между током и напряжением в функции времени.Отчет о международном поиске был опубликован 2004.05.27.The application describes a piezomotor consisting of a piezoelectric structural element (3) connected to a resonator and a two-dimensional resonator (2) interacting with a movable element, which has parallel main surfaces of the same shape and same size, while plane (8) of the symmetry of the resonator. The application also describes a method for manufacturing such piezomotors, whose resonators are made from a shaped molded product by cutting them from this molded product or from a metal sheet of constant thickness by cutting, preferably by cutting, from it. In addition, the application describes a method for exciting such a piezoelectric motor, in which the frequency or frequency of the excitation is generated using an electronic control system based on the corresponding magnitude of current increase and / or the corresponding minimum phase shift between current and voltage and / or change of phase shift between current and voltage as a function of time. The international search report was published on 2004.05.27.
