Arc-shaped (tile-shaped) neodymium iron boron motor magnets are professional magnetic components specially developed for various permanent magnet motors, generators and rotating electrical equipment, belonging to core functional magnetic materials in the motor industry. Adopting arc tile-shaped structural design and high-performance neodymium iron boron sintering process, the product is perfectly matched with the inner cavity radian of motor stators and rotors, which can form a uniform and stable rotating magnetic field, effectively improve the conversion efficiency of motor electric energy and magnetic energy, reduce motor energy consumption, and improve the power and stability of motor operation. It is widely used in household appliance motors, industrial motors, new energy vehicle motors, fan motors and various miniature precision motors.

In terms of structural design, the tile-shaped arc structure of motor neodymium iron boron magnets is optimized according to the internal electromagnetic field operation principle of the motor. The arc radian is precisely matched with the motor rotor and stator inner wall, with high fitting degree, no gap after assembly, uniform magnetic field distribution, no magnetic field distortion and magnetic leakage phenomenon. Compared with ordinary flat magnets, the arc-shaped structure can gather magnetic lines of force more effectively, improve the magnetic density of the motor working area, significantly enhance the motor torque and rotational power, and reduce the calorific value and operating noise of the motor during operation. The product has precise dimensional accuracy, consistent radian and thickness, which can ensure the consistency of magnetic field distribution of each group of motor components and avoid motor vibration and power attenuation caused by uneven magnet performance.

In terms of working performance, motor-grade tile-shaped neodymium iron boron magnets adopt high-temperature resistant high-grade neodymium iron boron materials (N35SH, N38SH, N40UH and other high-temperature resistant models), which can stably work in high-temperature environments of 120℃-180℃ for a long time, without demagnetization and performance attenuation, and adapt to the high-temperature and high-load continuous working state of motors. The product has high coercivity and strong anti-demagnetization ability, which can resist the reverse magnetic field interference generated during motor operation, ensure the stable output of motor magnetic field, and extend the service life of the motor. After surface nickel-copper-nickel multi-layer electroplating treatment, the product has excellent anti-corrosion and anti-rust performance, which can resist the humid and high-temperature working environment inside the motor and avoid magnetic steel failure caused by oxidation and corrosion.

Tile-shaped neodymium iron boron motor magnets cover the full range of motor application fields: in civil fields, they are used for air conditioner fan motors, washing machine motors, refrigerator motors, electric fan motors and other household appliance motors; in industrial fields, they are applied to industrial permanent magnet synchronous motors, servo motors, stepping motors and automation equipment drive motors; in new energy fields, they serve as core magnetic components of new energy vehicle drive motors, electric vehicle motors and wind power generation motors. With the advantages of high efficiency, energy saving, stable performance and long service life, this product is a key material for motor energy-saving upgrading and performance improvement, and occupies a core position in the motor manufacturing industry.
