{"id":55,"count":1,"description":"A \"Normally Open\" brake is a unit that is <strong>disengaged<\/strong> in its default, de-energized state. In this state, the shaft is free to rotate without any braking force being applied. To activate the brake and stop or hold the load, power must be supplied.    This is often referred to as a \"power-applied\" or \"energize-to-engage\" brake.    The principle of operation is the inverse of a spring-applied (fail-safe) brake:  <ul>   \t<li><strong>Stato predefinito (senza alimentazione):<\/strong>\u00a0There is no force\u2014or only a very light release spring force\u2014acting on the friction disc. The brake is \"open,\" and the shaft is free.<\/li>   \t<li><strong>Stato di frenatura (Accensione):<\/strong>\u00a0La potenza (tipicamente pressione idraulica, pressione pneumatica o una corrente elettrica che crea un campo magnetico) viene applicata attivamente per generare una forza di serraggio sul disco di attrito, attivando il freno e creando una coppia frenante.<\/li>  <\/ul>  <strong>Crucial Safety Implication:<\/strong> A \"Normally Open\" brake is <strong>non sicuro in caso di guasto<\/strong>. If there is a loss of control power or system pressure, the braking force is lost, and the brake will disengage.    <strong>Primary Applications:<\/strong> Because they are not fail-safe, \"Normally Open\" brakes are used for specific service or process control functions, not for critical safety holding:  <ul>   \t<li><strong>Controllo della Tensione:<\/strong>\u00a0In unwind stands for materials like paper, steel, or wire, a \"Normally Open\" pneumatic or electric brake can apply a continuous and precisely modulated amount of drag to maintain constant tension in the material as it is unspooled.<\/li>   \t<li><strong>Frenatura di servizio dinamica:<\/strong>\u00a0Vengono utilizzati come freno di servizio principale in applicazioni in cui \u00e8 installato anche un freno di emergenza o di parcheggio separato e a prova di guasto. Ad esempio, i freni di servizio su un veicolo o un carrello in movimento.<\/li>   \t<li><strong>Dinamometri:<\/strong>\u00a0Utilizzato per applicare un carico variabile e controllato per testare le prestazioni di motori e motori.<\/li>  <\/ul>  In summary, \"Normally Open\" describes a brake that requires power to stop a load. Its function is primarily for controlled, in-process braking, and it is fundamentally unsuitable for applications where a load must be safely held in the event of a power failure.","link":"https:\/\/www.takebrakes.com\/it\/tag\/normally-open\/","name":"Generalmente aperto","slug":"normally-open","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/tags\/55","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/posts?tags=55"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
