مغناطيس حلقي NdFeB

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. BMAG NdFeB annular magnets provide a clean, predictable field that is essential for precision calibration.

Because NdFeB contains high amounts of iron, protection is paramount. BMAG annular magnets feature advanced coating technology, including PTFE for specialized low-friction applications. The interior and exterior surfaces are treated to ensure that there are no “burrs” or uneven plating deposits that could interfere with tight-tolerance assemblies. We use laser-monitored grinding to ensure that the annular ring is perfectly balanced, reducing vibration in rotating applications and ensuring that the magnetic field is perfectly centered.
