Neodymium iron boron tile arc magnet is a special-shaped curved NdFeB permanent magnet processed by sintered NdFeB blank through wire cutting, grinding and arc finishing. The product presents tile-shaped and arc-shaped curved structure, with inner arc and outer arc matching the circular inner wall and outer wall of motor and rotating equipment, which is a professional magnetic component specially designed for rotating magnetic field equipment. Compared with ordinary block and sheet NdFeB magnets, the arc tile structure can perfectly fit the circular rotor and stator of the motor, make the magnetic field distribution more uniform and concentrated, reduce magnetic field loss, and greatly improve the operation efficiency of the motor. The product adopts high-purity NdFeB raw materials and advanced sintering process, with dense internal structure, stable magnetic performance and high structural strength.

In terms of performance advantages, neodymium iron boron tile arc magnets retain the ultra-high magnetic performance of NdFeB series products. The magnetic grade covers N35-N55, M, H, SH and other high and low temperature resistant grades, with high magnetic energy product, strong magnetic field strength and concentrated magnetic flux. The arc curved design makes the magnet form a uniform circular magnetic field after assembly, the magnetic field lines are distributed regularly, the magnetic gap is small, and the magnetic utilization rate is more than 20% higher than that of ordinary block magnets. The product has high dimensional accuracy, after professional arc grinding and fine processing, the arc curvature error is controlled within ±0.03mm, the radian is smooth and uniform, which can perfectly fit the inner cavity of the motor, ensuring the coaxiality and stability of motor rotation. In addition, the tile arc magnet has reasonable structural stress distribution, can withstand high-speed rotation centrifugal force and mechanical vibration, and is not easy to fall off and deform during long-term motor operation.

In terms of structural and environmental adaptability, neodymium iron boron tile arc magnets have excellent performance. The product supports customized processing of various radians, sizes and thicknesses, and can be made into thin tile, thick tile, large arc, small arc and special-shaped arc magnets according to the inner diameter and power requirements of different motors. The surface can be treated with zinc plating, nickel plating, epoxy coating and other anti-corrosion processes, which effectively improves the anti-rust and anti-corrosion ability of the magnet and adapts to the long-term continuous operation environment of the motor. The high-temperature resistant grade products can work stably at 120°C–180°C for a long time, with no demagnetization and stable magnetic field, meeting the high-load operation requirements of industrial motors. The product has strong anti-fatigue performance, and its magnetic performance and structural stability will not decay significantly after tens of thousands of hours of continuous operation, with long service life and low equipment maintenance cost.
