{"id":53,"count":1,"description":"In the field of industrial brakes, <strong>\u00c9conomie d'\u00e9nergie<\/strong> refers to a control technology, primarily for fail-safe electromagnetic brakes, that significantly reduces their electrical power consumption during operation. This is achieved by intelligently managing the voltage supplied to the brake's coil.    The core principle is based on a simple fact of electromagnetism: it requires substantially more magnetic force (and thus, more electrical power) to initially pull the armature across an air gap to <em>release<\/em> the brake than it does to simply <em>hold<\/em> the brake in the released position once the air gap is closed.    An energy-saving controller exploits this by implementing a two-stage power application:  <ol>   \t<li><strong>Suralimentation (Phase de suramplification) :<\/strong>\u00a0Pour un instant bref et pr\u00e9cis\u00e9ment chronom\u00e9tr\u00e9 (g\u00e9n\u00e9ralement en millisecondes) lors de la commande de d\u00e9blocage, le contr\u00f4leur envoie une haute tension (par exemple, 100 % de la tension continue nominale) \u00e0 la bobine du frein. Cela cr\u00e9e un champ magn\u00e9tique puissant qui surmonte rapidement et de mani\u00e8re d\u00e9cisive la force du ressort pour lib\u00e9rer le frein.<\/li>   \t<li><strong>Phase de maintien :<\/strong>\u00a0Immediately after the brake is released, the controller automatically reduces the output to a much lower \"holding voltage\" (often as low as 30-50% of the rated voltage). This reduced power level is more than sufficient to maintain the magnetic field required to hold the brake open against the springs.<\/li>  <\/ol>  Les avantages de cette approche sont triples et critiques pour les machines modernes :  <ul>   \t<li><strong>R\u00e9duction drastique de l'\u00e9nergie :<\/strong>\u00a0It can reduce the brake's energy consumption by up to 70% or more while the associated motor is running.<\/li>   \t<li><strong>R\u00e9duction de la g\u00e9n\u00e9ration de chaleur :<\/strong>\u00a0Less power consumption means the brake coil generates significantly less heat. This extends the life of the coil's insulation, improves the brake's performance consistency (preventing thermal fade), and reduces the thermal load on the adjacent motor.<\/li>   \t<li><strong>Dur\u00e9e de vie plus longue :<\/strong>\u00a0Un frein qui fonctionne \u00e0 une temp\u00e9rature plus basse est un frein plus fiable et plus durable.<\/li>  <\/ul>  Therefore, an energy-saving feature is not just about reducing electricity bills; it is a critical engineering advancement that enhances the brake's performance, reliability, and lifespan.","link":"https:\/\/www.takebrakes.com\/fr\/tag\/energy-saving\/","name":"\u00c9conomie d'\u00e9nergie","slug":"energy-saving","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/tags\/53","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/www.takebrakes.com\/fr\/wp-json\/wp\/v2\/posts?tags=53"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
