L'aimant torique NdFeB offre une combinaison unique de puissance magn\u00e9tique extr\u00eame et de polyvalence m\u00e9canique. Son centre creux en forme de \u201c\u00a0donut\u00a0\u201d n'est pas seulement un atout pour r\u00e9duire le poids\u00a0; c'est un \u00e9l\u00e9ment de conception fonctionnel qui permet de concentrer les lignes de flux vers le diam\u00e8tre int\u00e9rieur. De ce fait, l'aimant torique NdFeB est un choix exceptionnel pour les accouplements et assemblages magn\u00e9tiques o\u00f9 un arbre doit \u00eatre maintenu ou mis en rotation par des forces magn\u00e9tiques sans contact physique direct.<\/p>\n

Fabriqu\u00e9s \u00e0 partir de terres rares de tr\u00e8s haute puret\u00e9, les aimants annulaires BMAG pr\u00e9sentent une coercivit\u00e9 intrins\u00e8que \u00e9lev\u00e9e. Ils r\u00e9sistent ainsi tr\u00e8s bien aux perturbations de leur \u00e9tat magn\u00e9tique par des champs \u00e9lectriques externes ou d'autres aimants \u00e0 proximit\u00e9. Leur g\u00e9om\u00e9trie annulaire est obtenue par moulage haute pression, garantissant une densit\u00e9 homog\u00e8ne du bord int\u00e9rieur au bord ext\u00e9rieur et \u00e9vitant ainsi les zones de faible champ magn\u00e9tique. Chaque aimant est rev\u00eatu d'un traitement de surface multicouche Ni-Cu-Ni qui, outre sa protection contre la corrosion, renforce sa structure externe.<\/p>\n

The NdFeB Donut Magnet offers a unique combination of extreme magnetic strength and mechanical versatility. The hollow “donut” center is not just a weight-saving feature; it is a functional design element that allows for the concentration of flux lines toward the inner diameter. This makes the NdFeB donut an exceptional choice for magnetic couplings and […]<\/p>\n","protected":false},"featured_media":3604,"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":[36,15,105,111,123],"product_tag":[],"class_list":["post-3603","product","type-product","status-publish","has-post-thumbnail","product_cat-by-coating","product_cat-by-shape","product_cat-neodymium-ring-magnets","product_cat-nickel-plated","product_cat-speaker","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\/3603","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=3603"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media\/3604"}],"wp:attachment":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media?parent=3603"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_brand?post=3603"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_cat?post=3603"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_tag?post=3603"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
