Abstract
ANILLO MAGNETICO MULTIPOLAR COMPUESTO DESTINADO A MONTARSE EN UN ORGANO GIRATORIO EN EL QUE CADA ELEMENTO CONSTA DE UNOS DIENTES RADIALES REPARTIDOS CIRCUNFERENCIALMENTE, CUYA SEPARACION ES CONSTANTE, Y QUE FORMAN UNOS POLOS MAGNETICOS IDENTICOS. SE CARACTERIZA PORQUE ESTA CONSTITUIDO POR UN CONJUNTO DE DOS ANILLOS (4,4'') MAGNETICOS ELEMENTALES BIPOLARES AXIALMENTE IMBRICADOS EN EL QUE LOS POLOS MAGNETICOS DE UNO ESTAN ENCASTRADOS EN LOS POLOS MAGNETICOS DE POLARIDADES INVERSAS DEL OTRO.
