Con\u00e7us pour un fonctionnement continu et une grande fiabilit\u00e9, les aimants permanents pour moteurs BMAG sont fabriqu\u00e9s pour r\u00e9sister aux exigences rigoureuses de l'automatisation industrielle et de la propulsion automobile. Ces aimants \u00e9liminent le besoin d'enroulements de champ et de bagues collectrices, r\u00e9duisant ainsi les besoins de maintenance et les pertes par effet Joule (pertes cuivre) dans le rotor. Il en r\u00e9sulte un moteur fonctionnant \u00e0 une temp\u00e9rature plus basse et un rendement global du syst\u00e8me accru.<\/p>\n

Nous privil\u00e9gions le coefficient de temp\u00e9rature de r\u00e9manence (source Br) et de coercivit\u00e9 (source Hcj) de ces aimants. Ceci garantit une chute de puissance magn\u00e9tique minimale et pr\u00e9visible lors de l'\u00e9chauffement du moteur en fonctionnement, assurant ainsi une logique de commande stable. Les aimants sont soumis \u00e0 des tests rigoureux et sp\u00e9cialis\u00e9s, notamment le test de contrainte acc\u00e9l\u00e9r\u00e9e (HAST), afin de garantir l'int\u00e9grit\u00e9 du rev\u00eatement et la durabilit\u00e9 du substrat. Ils constituent le choix id\u00e9al pour les moteurs synchrones, les moteurs pas \u00e0 pas et les moteurs sans noyau \u00e0 haut rendement, pour lesquels la fiabilit\u00e9 est primordiale.<\/p>\n

Designed for continuous duty cycles and reliability, BMAG Motor Permanent Magnets are built to withstand the rigorous demands of industrial automation and automotive propulsion. These magnets eliminate the need for field windings and slip rings, reducing maintenance requirements and eliminating excitation losses (copper loss) in the rotor. This results in a cooler-running motor with higher […]<\/p>\n","protected":false},"featured_media":3550,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[36,15,104,111],"product_tag":[],"class_list":["post-3549","product","type-product","status-publish","has-post-thumbnail","product_cat-by-coating","product_cat-by-shape","product_cat-neodymium-arc-magnet","product_cat-nickel-plated","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product\/3549","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/comments?post=3549"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media\/3550"}],"wp:attachment":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media?parent=3549"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_brand?post=3549"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_cat?post=3549"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_tag?post=3549"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
