Abstract

CONSTA DE UN CILINDRO (2) QUE FORMA EL CUERPO DEL ROTOR, QUE SE PROLONGA A AMBOS LADOS DEL ARBOL (1) Y DE OCHO IMANES PERMANENTES ARQUEADOS (3A A 3H) DISPUESTOS SOBRE LA SUPERFICIE CILINDRICA DEL CUERPO DEL ROTOR (2). LOS IMANES (3A A 3H) ESTAN ENCOLADOS SOBRE EL ROTOR (2) Y POR SU FORMA DEJAN ENTRE ELLOS, EN EL SENTIDO AXIAL DE LOS INTERSTICIOS (A A H) UNA FORMA EN V. UN HILO (5) DE FIBRAS DE CARBONO PASA SUCESIVAMENTE POR CADA UNO DE LOS INTERSTICIOS (A A H) VARIAS VECES, APLICANDO UNAS FUERZAS DE COMPRESION SOBRE LAS CARAS INCLINADAS DE LOS IMANES (3A A 3H), LOS CUALES SON SOLIDAMENTE MANTENIDOS, DE ESTA FORMA, CONTRA EL ROTOR. LOS INTERSTICIOS SON DESPUES RELLENADOS DE UNA RESINA, OBTENIENDOSE UNA SUPERFICIE CONTINUADA.
