{"id":45,"count":1,"description":"In an elevator system, the brake is a non-negotiable, life-critical safety component whose primary function is to hold the elevator car stationary at a floor. Elevators universally employ <strong>fail-safe, spring-applied, DC electromagnetic brakes<\/strong> that are integrated directly with the hoist motor and gearbox, known as the traction machine.    The operational principle is built around inherent safety:  <ol>   \t<li><strong>Statische Halterung (Standardzustand):<\/strong>\u00a0Powerful mechanical springs exert a constant clamping force on a brake disc or drum coupled to the motor shaft. This is the brake's default, unpowered state, ensuring the elevator car is securely held in place and cannot move.<\/li>   \t<li><strong>Angetriebene Freigabe:<\/strong>\u00a0When a user calls the elevator, the control system sends an electrical current to the brake's electromagnetic coil\u00a0<em>im selben Moment<\/em>\u00a0sendet es Strom an den Antriebsmotor. Das resultierende Magnetfeld ist stark genug, um die Federkraft zu \u00fcberwinden, die Bremsbel\u00e4ge zur\u00fcckzuziehen und die Bremse freizugeben, gerade als der Motor zu drehen beginnt.<\/li>   \t<li><strong>Fail-Safe Engagement:<\/strong>\u00a0In dem Moment, in dem die Kabine die gew\u00fcnschte Etage erreicht, schneidet der Controller die Stromversorgung sowohl zum Motor als auch zur Bremsenspule ab. Das Magnetfeld kollabiert sofort, und die Federn setzen die Bremse wieder in Kraft, wodurch die Kabine sanft und pr\u00e4zise zum Stillstand kommt und auf gleicher H\u00f6he mit dem Boden bleibt. In jedem Stromausfallszenario tritt dieselbe Aktion ein, die garantiert, dass der Aufzug stoppt und sicher in Position bleibt.<\/li>  <\/ol>  Crucially, this primary electromagnetic brake is distinct from the elevator's emergency \"safeties\"\u2014the separate mechanical devices that are triggered by an overspeed governor to physically grip the guide rails in the rare event of a rope failure or uncontrolled descent. Modern safety standards (such as ASME A17.1\/CSA B44) mandate extreme redundancy in the primary brake itself, often requiring dual electrical coils or mechanically independent brake calipers to ensure that no single point of failure can compromise the system's holding capability.","link":"https:\/\/www.takebrakes.com\/de\/tag\/elevator\/","name":"Aufzug","slug":"elevator","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/de\/wp-json\/wp\/v2\/tags\/45","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=45"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
