Esto genera el par de frenado y mantiene el eje en reposo.<\/p>\n<p>&nbsp;<\/p>\n<p>Cuando se suministra aire comprimido al actuador, la presi\u00f3n de aire vence la fuerza de los muelles y retrae el disco de fricci\u00f3n, liberando el freno y permitiendo la rotaci\u00f3n libre del eje. El eje permanece libre mientras se mantiene la presi\u00f3n de aire por encima del umbral de apertura.<\/p>\n<p>&nbsp;<\/p>\n<p>Si la presi\u00f3n de aire cae por debajo del umbral de apertura, por una parada controlada, una parada de emergencia o un fallo en el suministro, los muelles vuelven a activar inmediatamente el disco de fricci\u00f3n y el freno retiene el eje. No se necesita se\u00f1al el\u00e9ctrica, comando de control ni acci\u00f3n del operario para que el freno act\u00fae ante una p\u00e9rdida de presi\u00f3n.<\/p>\n<h3 style=\"text-align: center;\">Freno neum\u00e1tico FNAM: caracter\u00edsticas t\u00e9cnicas principales<\/h3>\n<ul>\n<li>Muelle frena, aire abre (freno negativo de seguridad)<\/li>\n<li>Rango de par de frenado: 12 a 220 Nm<\/li>\n<li>Activaci\u00f3n autom\u00e1tica ante p\u00e9rdida de presi\u00f3n de aire, sin se\u00f1al de control<\/li>\n<li>Respuesta r\u00e1pida<\/li>\n<li>Par residual m\u00ednimo al abrir para rotaci\u00f3n libre del eje<\/li>\n<li>Funcionamiento fiable en condiciones de trabajo exigentes<\/li>\n<li>Apto para ciclos de parada de emergencia repetidos<\/li>\n<li>Bajo mantenimiento<\/li>\n<li>Para aplicaciones en ejes horizontales<\/li>\n<\/ul>\n<h3 style=\"text-align: center;\">Freno neum\u00e1tico de seguridad vs freno electromagn\u00e9tico de seguridad<\/h3>\n<p>Tanto el FNAM como los frenos electromagn\u00e9ticos de muelle (FDB, FDW) son dispositivos de seguridad que act\u00faan ante la p\u00e9rdida de suministro.
