Features & Applications

Arc Shape Epoxy Neodymium Material Magnet Supplier

High Magnetic Efficiency: The NdFeB core delivers strong magnetic flux in a compact arc shape, ideal for achieving efficient torque control in motor rotors or stators.
Corrosion-Resistant Epoxy Coating: The epoxy layer protects the magnet surface from humidity and oxidation, extending its service life.
Precision Manufacturing: Using wire cutting and grinding, we ensure tight geometric tolerances and clean segment edges.
Target Use Cases: Ideal for electric motors (BLDC, PMSM), generators, actuators, magnetic couplings, and other systems where curved magnet segments are needed.

Advantages for Industrial Buyers

Custom Magnet Solutions: We support bulk order and custom arc magnet projects - you can provide CAD drawings for tailored segmentation.
Stable Batch Quality: Each batch undergoes magnetic flux testing and dimensional inspection to guarantee performance consistency.
Cost Efficiency: Using segmented arc magnets reduces material waste compared to full ring cuts, lowering unit cost for large-scale production.
Long-Term Reliability: Epoxy coating resists environmental degradation, which makes these magnets well-suited for long-lifetime applications.
