Abstract

La presente invención se refiere a un rotor para máquina dinamoeléctrica, que comprende un núcleo que tiene una superficie cilíndrica externa, una pluralidad de imanes permanentes distribuidos equicircunferencialmente en torno a dicho núcleo, asegurándose dichos imanes a tope contra dicho núcleo y espaciados entre ellos con separaciones intermedias, un miembro de banda circundando a dichos imanes permanentes e incluyendo una porción de aseguramiento alineada con uno de dichos espacios, un medio de aseguramiento acoplado a dicha banda en alineación con por lo menos uno de dichos espacios y proyectándose hacia adentro en relación de sujeción con dicho núcleo, proyectándose dichos medios de aseguramiento hacia adentro entre dichos imanes y localizados totalmente hacia adentro de la circunferencia cilíndrica externa definida por la superficie externa de dichos imanes, forzando dichos medios de aseguramiento a dicha banda hacia adentro entre dichos imanes y estableciendo una fuerza de retención de la banda predeterminada en dicha banda para fijar seguramente a dichos imanes permanentes en relación con dicho núcleo, seleccionándose dicha fuerza para mantener a dichos imanes permanentes en posición bajo velocidad predeterminada de operación del rotor.
