{"id":53,"count":1,"description":"In the field of industrial brakes, <strong>Risparmio energetico<\/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>rilascio<\/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>Sovra-eccitazione (fase di boost):<\/strong>\u00a0Per un breve momento, precisamente temporizzato (tipicamente millisecondi), al comando di rilascio, il controller fornisce una tensione elevata (ad esempio, il 100% della tensione continua nominale) alla bobina del freno. Questo crea un campo magnetico potente che supera rapidamente e decisamente la forza della molla per rilasciare il freno.<\/li>   \t<li><strong>Fase di mantenimento:<\/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>  I vantaggi di questo approccio sono tripli e fondamentali per le macchine moderne:  <ul>   \t<li><strong>Riduzione drastica dell'energia:<\/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>Riduzione del calore generato:<\/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>Durata di servizio pi\u00f9 lunga:<\/strong>\u00a0Un freno che funziona a temperature pi\u00f9 basse \u00e8 un freno pi\u00f9 affidabile e durevole.<\/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\/it\/tag\/energy-saving\/","name":"Risparmio energetico","slug":"energy-saving","taxonomy":"post_tag","meta":[],"_links":{"self":[{"href":"https:\/\/www.takebrakes.com\/it\/wp-json\/wp\/v2\/tags\/53","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=53"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
