Il termine &quot;anulare&quot; indica un anello con uno specifico rapporto ottimizzato tra lo spessore della parete e il diametro complessivo. Questo rapporto \u00e8 fondamentale per mantenere un&#039;elevata &quot;permeabilit\u00e0 efficiente&quot;, che impedisce al magnete di lavorare contro se stesso. I magneti anulari BMAG e NdFeB forniscono un campo pulito e prevedibile, essenziale per la calibrazione di precisione.<\/p>\n<p>Poich\u00e9 il magnete NdFeB contiene elevate quantit\u00e0 di ferro, la protezione \u00e8 fondamentale. I magneti anulari BMAG sono dotati di una tecnologia di rivestimento avanzata, incluso il PTFE per applicazioni specializzate a basso attrito. Le superfici interne ed esterne vengono trattate per garantire l&#039;assenza di &quot;bave&quot; o depositi di placcatura irregolari che potrebbero interferire con gli assemblaggi con tolleranze ristrette. Utilizziamo la rettifica controllata da laser per garantire che l&#039;anello anulare sia perfettamente bilanciato, riducendo le vibrazioni nelle applicazioni rotanti e assicurando che il campo magnetico sia perfettamente centrato.<\/p>\n<h2>Schema dimensionale del magnete anulare NdFeB<\/h2>\n<p><a href=\"https:\/\/bwmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Dimension-Diagram.webp\" target=\"_blank\" rel=\"noopener\"><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-3598 size-full\" src=\"https:\/\/bwmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Dimension-Diagram-e1768354509893.webp\" alt=\"Diagramma di dimensione del magnete ad anello\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Dimension-Diagram-e1768354509893.webp 600w, https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Dimension-Diagram-e1768354509893-300x200.webp 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/a>&nbsp;<\/p>\n<p><span style=\"font-size: 1.7em; font-weight: bold;\">Magnete ad anello Direzione di magnetizzazione<\/span>&nbsp;<\/p>\n<p><a href=\"https:\/\/bwmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction.webp\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"wp-image-3599 size-full\" src=\"https:\/\/bwmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction.webp\" alt=\"Magnete ad anello Direzione di magnetizzazione\" width=\"2000\" height=\"400\" srcset=\"https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction.webp 2000w, https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction-300x60.webp 300w, https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction-1024x205.webp 1024w, https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction-768x154.webp 768w, https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction-1536x307.webp 1536w, https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction-18x4.webp 18w, https:\/\/www.bmagmagnet.com\/wp-content\/uploads\/2026\/01\/Ring-Magnet-Magnetization-Direction-600x120.webp 600w\" sizes=\"(max-width: 2000px) 100vw, 2000px\" \/><\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>BMAG NdFeB Annular Magnets are the preferred choice for engineers seeking a high-performance radial or axial flux source.
