Abstract
CIRCUITO DE ALIMENTACION DE UN MOTOR PIEZOELECTRICO QUE COMPRENDE UN ROTOR ARRASTRADO POR FRICCION POR UN ESTATOR EXCITADO POR AL MENOS DOS ELEMENTOS PIEZOELECTRICOS (P1, P2) ALIMENTADOS RESPECTIVAMENTE POR DOS TENSIONES ALTERNAS (VP, VA) DE IGUAL AMPLITUD Y DESFASADAS EN APROXIMADAMENTE 90 MEDIANTE UNA FUENTE UNICA Y UN MEDIO DESTINADO A GENERAR LAS DOS TENSIONES DESFASADAS. ESTE MEDIO ESTA CONSTITUIDO POR UN CONDENSADOR (C) EN SERIE CON UNO DE LOS ELEMENTOS PIEZOELECTRICOS (P2) Y CUYO VALOR SE ELIGE DE MANERA QUE PARA UNA FRECUENCIA DADA DE LA TENSION DE LA FUENTE (S) SE OBTIENE PRACTICAMENTE LA IGUALDAD DE LAS TENSIONES Y DE DESFASE DE 90 . LA TENSION DE LA FUENTE ES CONTROLADA VENTAJOSAMENTE, FRECUENCIALMENTE, POR UNA UNIDAD LOGICA DE TRATAMIENTO (ULT).
