Abstract

MOTORES ELECTRICOS PEQUEÑOS CON IMANES PERMANENTES DE GRAN RESISTENCIA CONTRA LA DESMAGNETIZACION DEBIDA AL CAMPO TRANSVERSAL DE INDUCIDO SIN AUMENTO DEL RUIDO MAGNETICO. CONSISTE EN UNOS IMANES PERMANENTES (11) QUE CONSTAN EN CADA CASO DE UN SEGMENTO (13) EN FORMA DE ARCO QUE DISMINUYE EN SU ESPESOR MEDIO RADIAL, HACIA SU EXTREMO, DE TAL FORMA QUE LA SUMA DEL VALOR DEL ENTREHIERRO Y DEL ESPESOR ES CONSTANTE EN CADA PUNTO, LOS DOS SEGMENTOS QUE FORMAN CADA IMAN PRESENTAN CARACTERISTICAS MAGNETICAS DISTINTAS, TENIENDO UNA SEPARACION ANGULAR ENTRE LAS SECCIONES QUE VIENE DADA POR LA RELACION DE SUS PROPIEDADES MAGNETICAS.
