Abstract
2.1. EN LOS USUALES APARATOS DE CINTA MAGNETICA CON UN TAMBOR FRONTAL IMPULSADO POR UN MOTOR, SE CALIENTA EL TAMBOR FRONTAL MEDIANTE UN ELEMENTO DE CALEFACCION, PARA EVITAR QUE SE CUBRA DE HUMEDAD. PARA ELLO SE DISPONE EL ELEMENTO DE CALEFACCION EN LA PARTE INFERIOR FIJA DEL TAMBOR FRONTAL MEDIANTE UNA ABRAZADERA METALICA. EL ELEMENTO DE CALEFACCION SE ALIMENTA CON ENERGIA A TRAVES DE UN CABLE DE UNION Y UNA CONEXION ELECTRONICA DE UNA FUENTE DE TENSION QUE SE ENCUENTRA EN LA RED DEL APARATO. LA TAREA CONSISTE EN REDUCIR EL ESFUERZO RELATIVAMENTE GRANDE PARA CALENTAR EL TAMBOR FRONTAL. 2.2. SE DISPONE EL ELEMENTO DE CALEFACCION (61) EN EL ESTATOR (95) DEL MOTOR (M) QUE, JUNTAMENTE CON EL TAMBOR FRONTAL (90), CONFORMA UNA UNIDAD MECANICA, DE MODO QUE NO SE REQUIEREN MEDIOS DE FIJACION ADICIONALES PARA EL ELEMENTO DE CALEFACCION (61). EL CALOR GENERADO POR EL ELEMENTO DE CALEFACCION (61) SE CONDUCE AL TAMBOR FRONTAL (90) A TRAVES DEL PAQUETE DE ESTATOR (95B), CONSISTENTE EN CHAPAS DE ACERO, YDE UNA CARCASA (93A) PARA EL EJE DEL MOTOR (99), QUE ESTA CONFORMADA EN LA PARTE INFERIOR (93) DEL TAMBOR FRONTAL Y QUE SE INTRODUCE DENTRO DEL ESPACIO DEL MOTOR. SE REDUCE AUN MAS EL ESFUERZO, APROVECHANDO LA TENSION DE MARCHA DEL MOTOR (UB2) PARA ALIMENTAR EL ELEMENTO DE CALEFACCION (61) Y DIRIGIENDO LA CONEXION ELECTRONICA (60, 70), QUE CONECTA EL ELEMENTO DE CALEFACCION (61), MEDIANTE LA CONEXION REGULADORA DEL MOTOR. 2.3. TAMBOR FRONTAL, ESPECIALMENTE PARA GRABADORA DE VIDEO.
