Les aimants annulaires BMAG et NdFeB sont le choix privil\u00e9gi\u00e9 des ing\u00e9nieurs recherchant une source de flux radial ou axial haute performance. Le terme \u201c\u00a0annulaire\u00a0\u201d d\u00e9signe un anneau dont le rapport entre l'\u00e9paisseur de paroi et le diam\u00e8tre total est optimis\u00e9. Ce rapport est essentiel pour maintenir une perm\u00e9ance \u00e9lev\u00e9e (Coefficient), emp\u00eachant ainsi l'aimant de fonctionner contre lui-m\u00eame. Les aimants annulaires BMAG et NdFeB fournissent un champ magn\u00e9tique propre et pr\u00e9visible, indispensable \u00e0 un \u00e9talonnage pr\u00e9cis.<\/p>\n

Du fait de sa forte teneur en fer, la protection des aimants annulaires NdFeB est primordiale. Les aimants annulaires BMAG b\u00e9n\u00e9ficient d'une technologie de rev\u00eatement avanc\u00e9e, notamment le PTFE pour les applications sp\u00e9cifiques \u00e0 faible friction. Les surfaces int\u00e9rieure et ext\u00e9rieure sont trait\u00e9es afin d'\u00e9liminer toute bavure ou irr\u00e9gularit\u00e9 de d\u00e9p\u00f4t susceptible de perturber les assemblages de haute pr\u00e9cision. Le meulage sous contr\u00f4le laser garantit un \u00e9quilibrage parfait de l'anneau, r\u00e9duisant ainsi les vibrations dans les applications rotatives et assurant un centrage optimal du champ magn\u00e9tique.<\/p>\n

BMAG NdFeB Annular Magnets are the preferred choice for engineers seeking a high-performance radial or axial flux source. The term “annular” denotes a ring with a specific, optimized ratio between the wall thickness and the overall diameter. This ratio is critical for maintaining a high “Permeance Coefficient,” which prevents the magnet from working against itself.
