Abstract

PARA DETENER CON SEGURIDAD EL DISCO (CD) CON INDEPENDENCIA DE SU TAMAÑO Y DE SU MOMENTO DE INERCIA DE MASA, UN PRIMER IMPULSO DE FRENADO (B1) CAUSA QUE EL DISCO (CD) FRENE HASTA LA DETENCION Y A CONTINUACION SE ACELERE EN DIRECCION OPUESTA. DURANTE ESTE TIEMPO SE MIDE EL TIEMPO T QUE TRANSCURRE HASTA QUE EL NUMERO DE REVOLUCIONES DEL DISCO (CD), A CONSECUENCIA DEL PRIMER IMPULSO DE FRENADO (B1), HA CAMBIADO DESDE UN VALOR PREFIJABLE +N AL VALOR -N. EN ESTE MOMENTO SE INVIERTE LA POLARIDAD DEL PRIMER IMPULSO DE FRENADO (B1) Y EL SEGUNDO IMPULSO DE FRENADO (B2) ASI FORMADO, FINALIZA DESPUES DEL TIEMPO T/2. POR ELLO SE FRENA EL DISCO (CD) CON SEGURIDAD Y RAPIDEZ DESDE EL NUMERO DE REVOLUCIONES -N HASTA EL REPOSO.
