Fan-shaped high-strength NdFeB magnetic steel is a fan-shaped special permanent magnet processed from high-performance NdFeB raw materials, with a sector outline formed by two straight sides and two arc sides, including inner arc and outer arc structures, which is specially designed for circular rotating equipment and fan-shaped assembly spaces. As a core special-shaped magnetic steel product, it integrates the ultra-strong magnetic properties of NdFeB materials and the structural advantages of fan-shaped geometry, and is widely used in various motor, generator, and rotating mechanical equipment that require circular array assembly. The product is sintered and formed by high-purity NdFeB magnetic powder, with dense internal structure, uniform magnetic field distribution, and strong magnetic permeability, and the overall magnetic performance is far superior to ordinary ferrite fan-shaped magnets.

In terms of performance and specifications, fan-shaped NdFeB magnetic steel supports full-size customized production, with customizable inner arc radius, outer arc radius, central angle, and thickness parameters, covering micro miniature fan-shaped magnetic steel for small motors and large-size fan-shaped magnetic steel for industrial large equipment. The product adopts high-temperature sintering and secondary tempering process, with stable magnetic performance, high coercivity, and strong anti-demagnetization ability, and can work stably for a long time in high-temperature and high-speed rotating environments. High-temperature resistant grades such as SH and UH can withstand high temperatures of 180°C-200°C without magnetic attenuation, meeting the long-term operation needs of high-power motors. The surface is treated with anti-corrosion electroplating, which can effectively resist oxidation, rust, and chemical corrosion, and adapt to harsh working environments such as high-speed rotation, vibration, and heat generation of motors. The fan-shaped structure can be closely arranged in a circular array, with no gaps between adjacent magnetic steels, realizing uniform and closed magnetic field circulation, and greatly improving the operating efficiency of rotating equipment.

Fan-shaped high-strength NdFeB magnetic steel is the core component of various rotating power equipment. In the new energy vehicle industry, it is widely used in drive motors, generator motors, and steering motors of new energy vehicles, providing stable magnetic field power for vehicle motors, improving motor power density and energy conversion efficiency, and reducing motor volume and weight. In the industrial motor industry, fan-shaped magnetic steel is applied to high-efficiency energy-saving motors, servo motors, variable frequency motors, and wind power generator motors, helping industrial motors achieve high efficiency, low energy consumption, and stable operation. In the household appliance and intelligent equipment industry, it is used for fan motors, air conditioner motors, robot joint rotating motors, and miniature rotating power components. In addition, it is also used in aerospace rotating equipment, precision instrument motors, and industrial automation rotating machinery. Compared with other shaped magnetic steels, fan-shaped NdFeB magnetic steel has the best matching degree with circular rotating structures, can form a uniform and stable rotating magnetic field, effectively reduce motor torque loss, improve equipment operation stability, and is an indispensable core magnetic material in the field of modern high-efficiency motor manufacturing and new energy power equipment.
