Abstract

DISPOSITIVO REGULADOR DE VELOCIDAD DEL PLATO GIRATORIO DE UN APARATO DE VIDEO DISCO. CONSTA DE DOS MECANISMOS, UNO DE TRANSMISION DEL PLATO GIRATORIO (24) Y OTRO DE REGULACION DE LA VELOCIDAD DE DICHO PLATO (26). EL PRIMERO SE COMPONE DE UN MOTOR ELECTRICO, CUYO ESTATOR (28) LLEVA SUJETOS UN PAR DE ELEMENTOS (52, 54) TERMINADOS, RESPECTIVAMENTE, EN DOS POLOS (56, 58), Y DE UN DEVANADO INDUCTOR (34) SITUADO ALREDEDOR DEL ESTATOR (38). EL SEGUNDO MECANISMO (26) COMPRENDE UN ANILLO MAGNETICO (50), CONSTITUIDO POR UN NUMERO PAR DE POLOS ALTERNOS Y SUJETO A LA PESTAÑA ANULAR 844) UNIDA AL PLATO MEDIO DE LA CORREA ELASTICA DE TRANSMISION (38). LA VELOCIDAD DE ROTACION DEL MOTOR Y LAS DIMENSIONES DE LAS POLEAS (40, 44) SE ELIGEN DE MODO QUE EL PLATO (12) GIRE A LA VELOCIDAD DE ROTACION PREDETERMINADA. EL NUMERO DE PARES DE POLOS ALTERNOS DEL ANILLO MAGNETICO (50) SE ELIGE EN FUNCION DE LA FRECUENCIA DE LA FUENTE DE ALIMENTACION ELECTRICA Y DE LA VELOCIDAD DE ROTACION DEL PLATO (12).
