Abstract
SE PRESENTA UN MOTOR QUE GENERA FUERZA MOTRIZ UTILIZANDO LA DEFORMACION TANGENCIAL QUE RESULTA DEL CONTACTO ELECTRICO ENTRE UN ELEMENTO GIRATORIO Y UNA CAPA DE MATERIAL QUE EXPERIMENTA UNA DEFORMACION TANGENCIAL EN RESPUESTA AL CAMPO ELECTRICO APLICADO. EN UNA CONFORMACION PIEZOELECTRICA DEL GIRO, LA ROTACION DEL EJE DE UN MOTOR ES EL RESULTADO DE LA INTENSIDAD DEL CAMPO ELECTRICO NO UNIFORME QUE SE GENERA ALREDEDOR DE LOS CONTACTOS ENTRE LOS CILINDROS QUE RODEAN EL EJE Y LA CARRERA EXTERIOR DE UN MATERIAL PIEZOELECTRICO QUE SUFRE UNA DEFORMACION TANGENCIAL. LA ROTACION SE PRODUCE A MEDIDA QUE LOS CILINDROS GIRAN BAJO EL FRENTE DE ONDAS TANGENCIALES PIEZOELECTRICAS QUE SE DESPLAZAN CON LOS CILINDROS. LOS CILINDROS REALIZAN LA FUNCION DE CONMUTADORES, PERO SIN NINGUNA FRICCION DESLIZANTE, Y ELIMINAN LA NECESIDAD DE LOS TRADICIONALES SOPORTES. DE LA INEXISTENCIA DE ESPACIOS VACIOS ENTRE LAS PIEZAS DEL MOTOR SE SIGUE LA RIGIDEZ DEL EJE LO QUE PERMITE UN PRECISO POSICIONAMIENTO EN EL FUNCIONAMIENTO A ALTA VELOCIDAD. EL MOTOR PIEZOELECTRICO PRESENTA UNA ALTA EFICIENCIA A CAUSA DE QUE LA FRICCION DESLIZANTE SE ELIMINA, NO SE GENERAN CORRIENTES PARASITAS, Y LA MAYOR PARTE DE LA CORRIENTE QUE FLUYE EXTERNAMENTE ES LOCAL Y REACTIVA. LA EFICIENCIA DEL MOTOR EXCEDE DEL 98%, Y SU FUNCIONAMIENTO SUAVE Y SILENCIOSO ES CAPAZ DE VELOCIDADES REALMENTE ALTAS. LA VELOCIDAD DEL MOTOR SE CONTROLA VARIANDO EL POTENCIAL DE CORRIENTE CONTINUA. EL MOTOR PUEDE HACERSE FUNCINAR POR MEDIO DE UNA BATERIA, NO REQUIERE LUBRIFICACION, Y FUNCIONARA AUMQUE SE INUNDE CON FLUIDOS ESCASAMENTE CONDUCTORES, TALES COMO AGUA SALADA. LA ESCALA DEL MOTOR PUEDE ALCANZAR DESDE LA MINIATURA PARA IMPULSAR UN MOTOR HASTA UN TAMAÑO REALMENTE GRANDE PARA IMPULSAR UN BARCO TRANSATLANTICO.
