Abstract

DISPOSITIVO DE ACCIONAMIENTO DE VENTILADOR CON RUIDO REDUCIDO PARA MAQUINA GIRATORIA ELECTRICA. CONSTA DE UN VENTILADOR DE REFRIGERACION POR AIRE (15) QUE ESTA MONTADO EN UN EJE (7) DEL ROTOR POR MEDIO DE UN COJINETE (14), UNA PLURALIDAD DE PARES DE IMANES (16A, 16B) MONTADOS EN DICHO ROTOR Y UN DISCO NO FERROSO (17) MONTADO EN EL VENTILADOR Y QUE ESTA PROVISTO DE UN REBORDE ANULAR SITUADO ENTRE LOS PARES DE IMANES. EL VENTILADOR ESTA ACCIONADO POR LA INTERACCION ENTRE LOS IMANES Y LAS CORRIENTES DE FONCAULT INDUCIDAS EN EL REBORDE DEL DISCO. ADMITE ALTERNATIVAS DE POSICION DE LOS ELEMENTOS. ESPECIALMENTE APLICABLE A MOTORES ELECTRICOS.
