{"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>Standardzustand (Strom aus):<\/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>Bremszustand (Leistung eingeschaltet):<\/strong>\u00a0Leistung (typischerweise hydraulischer Druck, pneumatischer Druck oder ein elektrischer Strom, der ein Magnetfeld erzeugt) wird aktiv angewendet, um eine Klemmkraft auf die Reibscheibe auszu\u00fcben, die Bremse zu bet\u00e4tigen und Bremsmoment zu erzeugen.<\/li>  <\/ul>  <strong>Crucial Safety Implication:<\/strong> A \"Normally Open\" brake is <strong>nicht ausfallsicher<\/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>Spannungsregelung:<\/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>Dynamische Betriebsbremse:<\/strong>\u00a0Sie werden als prim\u00e4re Betriebsbremse in Anwendungen verwendet, bei denen auch eine separate, ausfallsichere Not- oder Parkbremse installiert ist. Zum Beispiel die Betriebsbremsen an einem Fahrzeug oder einem beweglichen Wagen.<\/li>   \t<li><strong>Dynamometer:<\/strong>\u00a0Wird verwendet, um eine variable, kontrollierte Last anzuwenden, um die Leistung von Motoren und Antrieben zu testen.<\/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\/de\/tag\/normally-open\/","name":"Normalerweise ge\u00f6ffnet","slug":"normally-open","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/de\/wp-json\/wp\/v2\/tags\/55","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.takebrakes.com\/de\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.takebrakes.com\/de\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.takebrakes.com\/de\/wp-json\/wp\/v2\/posts?tags=55"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
