Arc tile-shaped motor magnet is a special curved permanent magnet component specially designed for motor rotor and stator structures, mostly made of high-performance sintered NdFeB or high-grade ferrite magnetic materials through special mold pressing and arc finishing processing. The product is arc tile-shaped in overall structure, with curved outer arc surface and flat inner surface, which perfectly fits the cylindrical inner cavity of the motor and the arc surface of the rotor. Different from flat conventional magnets, the arc tile-shaped structure can form a uniform circular closed magnetic field inside the motor, which effectively improves the magnetic field utilization rate and motor conversion efficiency, and is a core customized magnetic component dedicated to all kinds of permanent magnet motors. According to the performance grade, it is divided into high-temperature resistant NdFeB tile-shaped magnets and conventional ferrite tile-shaped magnets, which are applicable to high-power high-efficiency motors and low-power ordinary motors respectively.

In terms of structural and performance advantages, the arc tile-shaped motor magnet has a highly fitted arc structure, which can be closely attached to the motor rotor and stator mounting surface, with no gap and high fitting degree, avoiding magnetic field leakage caused by assembly gaps and greatly improving the effective utilization rate of magnetic energy. The product has uniform arc curvature and consistent magnetic field distribution, which can form a stable and uniform rotating magnetic field inside the motor, make the motor operation more stable, reduce vibration and noise, and improve motor power and operation efficiency. High-grade NdFeB arc tile-shaped magnets have ultra-high magnetic energy product and high-temperature resistance, can work stably at 150℃-200℃ for a long time, resist high-temperature demagnetization generated by motor operation, and ensure the long-term stable power output of the motor. After precision arc grinding and chamfering treatment, the product has smooth surface, accurate curvature size and small assembly tolerance, which is convenient for rapid assembly and fixing of motor production. The surface is treated with anti-corrosion electroplating, which has strong wear resistance and anti-aging ability, adapting to the high-speed rotating and high-temperature working environment of the motor.

Arc tile-shaped motor magnets are exclusively used in various permanent magnet motor equipment and are the core key components to determine motor performance. In the new energy vehicle industry, high-performance NdFeB arc tile-shaped magnets are used in drive motors, vehicle-mounted generator motors and auxiliary motor systems of new energy vehicles, providing high-efficiency power output for vehicles and improving vehicle endurance and power performance. In the industrial motor field, they are applied to permanent magnet synchronous motors, brushless motors, servo motors and variable frequency motors, which are widely used in industrial production equipment, mechanical transmission equipment and automated production lines, improving industrial motor energy-saving efficiency and operation stability. In the civil motor field, ferrite arc tile-shaped magnets are used for small household appliance motors such as fan motors, water pump motors and air conditioner motors, as well as toy motors and small power motors. In addition, arc tile-shaped motor magnets are also widely used in wind power generation motors, aerospace precision motors, medical equipment motors and intelligent robot drive motors. With the continuous promotion of energy-saving and efficient motors globally, the market demand for high-precision arc tile-shaped motor magnets is constantly expanding.
