Neodymium Arc Magnet for Motor Rotor N52
Neodymium Arc Magnet for Motor Rotor N52
Product Description
Permanent Neodymium Arc Magnet (NdFeB)
Our neodymium arc magnets (segment magnets) are made from high-performance NdFeB (Neodymium Iron Boron), offering strong magnetic flux, high energy density, and stable performance. Available in N35–N52 grades, including high-temperature options (H, SH, UH), these magnets are designed for motor and generator applications.
With precise curvature, uniform magnetization, and tight tolerances, arc magnets improve magnetic efficiency and motor performance. Multiple coatings, such as NiCuNi, Epoxy, and Zinc, ensure excellent corrosion resistance. Custom radius, angle, thickness, and magnetization direction are supported.
