Abstract

EL ESTATOR DEL MOTOR COMPRENDE UN BASTIDOR (15) CON AL MENOS UN PAR DE TRANSDUCTORES QUE COMPRENDEN CADA UNO UN ELEMENTO VIBRADOR, DISPUESTOS COLINEALMENTE Y ACTIVADOS DE MANERA QUE SUS ELEMENTOS VIBRADORES VIBREN A UNA MISMA FRECUENCIA, PERO CON UN DESFASE DE 90 (GRADOS) , Y UN MEDIO DE ACOPLAMIENTO (3) AL QUE SE APLICAN LAS VIBRACIONES Y AL MENOS UN ROTOR (10, 11) ACCIONADO POR FROTAMIENTO POR EL MEDIO DE ACOPLAMIENTO. EL MEDIO DE ACOPLAMIENTO (3) ES UNA PIEZA ELASTICA DE FORMA AL MENOS APROXIMATIVAMENTE ELIPTICA O SEMIELIPTICA O EN ASA DE CESTA, FIJADA EN DOS PUNTOS OPUESTOS A LOS TRANSDUCTORES. LA PIEZA DE ACOPLAMIENTO CUMPLE LA TRIPLE FUNCION DE ACOPLADOR DE VIBRACIONES, DE TRANSFORMADOR GEOMETRICO DE VIBRACIONES Y DE TRANSFORMADOR MECANICO DE AMPLITUDES.
