{"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>Estado Padr\u00e3o (Desligado):<\/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>Estado de Frenagem (Ligado):<\/strong>\u00a0A energia (tipicamente press\u00e3o hidr\u00e1ulica, press\u00e3o pneum\u00e1tica ou uma corrente el\u00e9trica criando um campo magn\u00e9tico) \u00e9 aplicada ativamente para gerar uma for\u00e7a de aperto no disco de fric\u00e7\u00e3o, engatando o freio e criando torque de frenagem.<\/li>  <\/ul>  <strong>Crucial Safety Implication:<\/strong> A \"Normally Open\" brake is <strong>n\u00e3o seguro contra falhas<\/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>Controle de Tens\u00e3o:<\/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>Frenagem de Servi\u00e7o Din\u00e2mica:<\/strong>\u00a0Eles s\u00e3o usados como o freio de servi\u00e7o principal em aplica\u00e7\u00f5es onde um freio de emerg\u00eancia ou de estacionamento separado e \u00e0 prova de falhas tamb\u00e9m est\u00e1 instalado. Por exemplo, os freios de servi\u00e7o em um ve\u00edculo ou em um carrinho em movimento.<\/li>   \t<li><strong>Dinam\u00f4metros:<\/strong>\u00a0Usado para aplicar uma carga vari\u00e1vel e controlada para testar o desempenho de motores e motores.<\/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\/pt\/tag\/normally-open\/","name":"Normalmente Aberto","slug":"normally-open","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/pt\/wp-json\/wp\/v2\/tags\/55","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.takebrakes.com\/pt\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.takebrakes.com\/pt\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.takebrakes.com\/pt\/wp-json\/wp\/v2\/posts?tags=55"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
