Description

M353575 Eight, new description: [New technology field] This creation is about a piezoelectric motor, especially a square matrix piezoelectric motor. [Prior Art] In the white technology, the linear motion of the linear slide can be quickly moved or manipulated on a linear platform, and the structural design is becoming more and more simple. For example, the early die-shaped (兀-shaped) piezoelectric motor • [1]' has two piezoelectric ceramic sheets attached to the P1-shaped (π-shaped) metal structure. In operation, as long as the two piezoelectric ceramics are applied with a driving voltage (v"c〇s(〇t 〇r/and Vppsi(10)t) and the resonant frequency 'can be crushed Pi-shaped) piezoelectric motor on a linear platform Quickly move or fiddle with the linear slide movement. This kind of Pi shape (the shape of the motor is simple structure and low manufacturing cost; but the disadvantage is that 1 sticks to the piezoelectric pottery "more troublesome" if the adhesive is not enough or the adhesive strength is not enough , there will be a situation in which the resonance of the resonance is not solved, and the fact that the piezoelectric flashing film is detached or peeled off. The other disadvantage is that the piezoelectric motor composed of the single-layer piezoelectric ceramic has a higher driving force and load capacity. In order to improve the shortcomings of the actuation force and the one-load capability, another type of Η-shaped (four) piezoelectric motor is embedded in the P1-shaped (π-shaped) metal structure to laminate the piezoelectric ceramics, thereby increasing the pressure 7 The object is lost. The machine, the tank of the squadron, the pressure of the Weiqi, is not easy to touch. If the squeezing is too low, then it is a total of _ _ _ now; the pre-stress is too high, following the piezoelectric coffee, A crab-shaped piezoelectric motor [3], which has the same shape as a crab, and is in the shape of a gate-shaped metal base 5 M353575 5Q) is composed of two kinds of chelate, which are composed of the same; the operation mode is reversed, and f p. The piezoelectric ceramics of the laminated layer is the manufacturing cost ☆ factory 4Pl (four) piezoelectric motor. However, the relative lack of this ... (four) Tao ^ paste and prestress adjustment is not easy, and its load is not clear _ gain. . The member of the square piezoelectric horse _, its gamma four piezoelectric actuators, square base and resistance ΓΓ ΓΓ is characterized by: the plant's electro-active components are made of hollow long cylindrical piezoelectric ceramics. Electrode coating was performed on both sides of the silk fabric. In addition, the bottom part of the four electric actuating elements is provided with a wear-resistant element', and its operation and principle are consistent with the aforementioned piezoelectric motor. The advantage of the electric motor is that the driving force and the load capacity are high, but the disadvantage of the electric motor is that the hollow circular long cylindrical piezoelectric shouting sintering and the electrode coating are not P and the hollow round long cylindrical piezoelectric pottery and wear resistance The assembly of the components is a bit cumbersome. In view of the above-mentioned conventional piezoelectric motor, the present invention still has its relative disadvantages, and designs a piezoelectric motor having the advantages of simple structure, high load capacity, easy manufacture and convenient assembly.
