Abstract

SE PRESENTA UNA DISPOSICION DE PROTECCION DE MICA PARA EL ARROLLAMIENTO DE ESTATOR DE UNA MAQUINA ELECTRICA, ABARCANDO UNA BANDA DE PROTECCION DE MICA SEMICONDUCTORA ARROLLADA ALREDEDOR DEL AISLAMIENTO PRINCIPAL DE LA PARTE DE RANURA Y DE LA PARTE DE ESTRIBO FRONTAL DE CADA UNA DE LAS BARRAS DEL ARROLLAMIENTO DE ESTATOR. ESTANDO CONSTITUIDO DE TAL FORMA, QUE LA PARTE (10) DE RANURA DE LA BARRA DEL ARROLLAMIENTO DE ESTATOR ESTA ARROLLADA CON UNA PRIMERA BANDA (24) DE PROTECCION DE MICA CONDUCTORA VOLUMETRICA Y SEMICONDUCTORA CON UN GRADO DE SOLAPE APROXIMADAMENTE CONSTANTE EN AL MENOS UNA CAPA. LA PARTE DE ESTRIBO FRONTAL ESTA DEVANADA CON UNA SEGUNDA BANDA (24) DE PROTECCION DE MICA CONDUCTORA VOLUMETRICA DE TIPO SEMICONDUCTOR EN AL MENOS UNA CAPA, CON LO QUE EL GRADO DE SOLAPE A PARTIR DE LA SALIDA DE LA BARRA PROCEDENTE DEL CUERPO (14) DE ESTATOR ES PEQUEÑA DE FORMA CONTINUA HACIA ADENTRO EN DIRECCION DEL EXTREMO DE LA BARRA. ESTA DISPOSICION DE PROTECCION DE MICA PUEDE SER FABRICADA DE FORMA ECONOMICA; LA DISTRIBUCION DE LA TENSION EN LA DIRECCION LONGITUDINAL DE LA BARRA SE OPTIMIZA DE FORMA SENCILLA.
