摘要： A method for manufacturing a spiral piezoelectric actuator using a thermoplastic material and the spiral piezoelectric actuator, and a micromini ultrasonic motor are provided to obtain a sufficient piezoelectric characteristic by performing the sintering using the thermoplastic property after making one feedrod composed of a piezoelectric element and an inert compound and extruding the feedrod through co-extrusion method. The pulverized PZN-PZT powder sintered at low temperature is made by mixing PZN made of Pb, Zn, and Nb and PZT made of Pb, Zn, and (Ti) with a predetermined ratio(S1). A piezoelectric element is made by adding polymer to the PZN-PZT powder(S2). A compound is made by adding the polymer after mixing the PZN-PZT power with Ag(S3). After forming the feedrod with a square pillar of the piezoelectric actuator composed of two-layer plate shape by co-extruding the piezoelectric element and the compound, the feedrod is cut(S4). The feedrod with a predetermined size is processed with a spiral shape in a furnace(S5). The spiral piezoelectric actuator composed of a piezoelectric layer and a compound layer is formed by performing the sintering at high temperature while combusting the polymer by heating the spiral feedrod at high temperature(S6).

摘要： A multilayer 2-2 piezo-composite ultrasonic transducer and a manufacturing method thereof are provided to cause a large displacement by a low voltage and to use a wide range of frequency. Two first inner electrode layers are exposed from a left side of a piezoceramic plate and directly contacted with a first outer electrode layer. The first inner electrode layers are not exposed from a right side of the piezoceramic plate but buried under a piezoelectric layer apart from a second outer electrode layer. Two second inner electrode layers are arranged to be opposed to the first inner electrode layers and contacted with the outer electrode layer, which is not contacted with the first inner electrode layers. The first and second inner electrode layers are alternatively arranged in the piezoelectric layers. When electric power is supplied to the outer electrode layers, a voltage is induced between the first and second inner electrode layers.

본 발명에 따른 압전 초음파 모터의 제조 방법은 저온 소결이 가능한 납(Pb), 아연(Zn), 니오브(Nb)로 조성되는 PZN과 납(Pb), 아연(Zn), 티타늄(Ti)으로 조성되는 PZT가 소정 비율로 혼합된 PZN-PZT 파우더와 폴리머를 혼합하여 압전체를 제조하는 압전체 제조 공정과; 상기 압전체 제조 공정에 의해 제조된 PZN-PZT 파우더와 은(Ag)을 소정 비율로 혼합된 파우더에 폴리머를 혼합하여 복합체를 제조하는 복합체 제조 공정과; 상기 압전체 및 복합체 제조 공정에 의해 제조된 압전체 및 복합체와 카본 블랙을 이용하여 상기 압전 모터의 초기 형상에 따른 피드로드(Feedrod)를 제작하는 피드로드 제작 공정과; 제작된 상기 피드로드(Feedrod)를 소정 크기의 성형 틀을 통해 사출하고 사출된 압전 모터 시편을 소정 크기로 절단하는 사출 공정;을 포함하는 것을 특징으로 한다.
따라서, 서로 다른 소재를 하나의 피드로드(Feedrod)로 제작하고, 제작된 피드로드(Feedrod)를 동시에 사출시켜 압전 초음파 모터를 제조함으로써, 충분한 압전효과를 가질 수 있는 압전체 및 구동력이 우수한 압전 초음파 모터를 적은 비용과 제조할 수 있는 장점이 있다.
