Abstract

"MOTOR PIEZELéTRICO". Um motor piezelétrico tem um atuador (26) que aciona um cursor (24). O atuador tem um núcleo de aço retangular de seção transversal quadrada com uma ponta de acionamento de projeção axial (28). Um elemento piezelétrico cerâmico (40) é unido a cada uma das quatro faces do núcleo. Cada elemento piezelétrico tem quatro quadrantes cobertos por eletrodos de quadrante (40a - 40d) em um lado e um eletrodo comum ou de terra no outro lado contatando o núcleo que une eletricamente os eletrodos comuns. Por excitação seletiva de quadrantes diagonalmente opostos correspondentes de elementos piezelétricos opostos, o atuador é feito acionar a ponta em qualquer direção X ou direção Y. O cursor preferido é uma bola esférica retida cativa dentro de braços se estendendo de um alojamento do atuador. A ponta de acionamento é apertada contra a bola por uma mola de pré-carga (34) atuando no atuador. A operação do atuador faz a bola (24) girar sobre um eixo X ou sobre um eixo Y produzindo um movimento bidimensional de um único motor e único atuador.
