Abstract

SISTEMA DE PROPULSION DE CINTA MAGNETICA SIN RODILLO DE PRESION. LA CINTA MAGNETICA (3) SE EMPULSA POR UN TAMBOR DE ARRASTRE (4), MOVIDO POR UN MOTOR (5) DE VELOCIDAD CONOCIDA Y AJUSTABLE, ACOPLADO CON DETECTORES DE INTENSIDAD (9) Y ACELERACION (9), QUE ENVIAN SUS SEÑALES A UN GENERADOR DE SEÑAL DE CONTROL (11), DONDE SE COMPARAN A UNA SEÑAL DE REFERENCIA (12) PARA PRODUCIR SEÑALES DE ALIMENTACION PARA LOS MOTORES (6, 7) DE LOS TAMBORES DE RECOGIDA (2) Y ALIMENTACION (1) DE CINTA (3). EL MOTOR DE ALIMENTACION (7) SE PUEDE SUSTITUIR POR UN SISTEMA DE FRENADO. APLICACION A GRABADORES Y REPRODUCTORES DE CINTAS DE AUDIO Y VIDEO.
