Abstract

SE DESCRIBE UN ROTOR CON IMANES PERMANENTES PARA UN MOTOR ELECTRICO QUE COMPRENDE UNA PLURALIDAD DE IMANES (2, 20) DISPUESTOS ALREDEDOR DE LA SUPERFICIE CIRCUNFERENCIAL DE UN NUCLEO (1, 10) DEL ROTOR Y EQUIESPACIADOS ENTRE SI, UNA CUBIERTA EXTERNA (40) QUE FIJA LOS IMANES AL NUCLEO DEL MOTOR, ESTANDO CADA IMAN (20) SENTADO SOBRE EL NUCLEO (10) A TRAVES DE LOS MEDIOS DE SOPORTE CORRESPONDIENTES (30, 50, 60) QUE ESTAN RETENIDOS DE SU DESPLAZAMIENTO CON RESPECTO A CADA IMAN (20), ESTANDO CADA UNO SITUADO SEGUN UNA ALINEACION PARALELA ENTRE SI Y AL ACCESO DEL MOTOR, SIMETRICAMENTE EN RELACION A UN PLANO DE SIMETRIA (X) LONGITUDINAL DEL IMAN (20) Y SEPARADOS ENTRE SI POR UNA DISTANCIA MENOR QUE LA DISTANCIA ENTRE LOS BORDES (21) LATERALES DISTALES DEL IMAN (20), CON OBJETO DE MINIMIZAR LA DISTANCIA ENTRE LAS REGIONES EN LAS QUE LA FUERZA DE REACCION ENTRE EL NUCLEO DEL ROTOR (10) Y LA CUBIERTA EXTERNA (40) SE APLICA SOBRE CADA IMAN (20) CON CONDICIONES DE TEMPERATURA DIFERENTES DEL ROTOR.
