New energy motor permanent magnet steel is a high-performance sintered neodymium iron boron permanent magnet material specially used for new energy vehicle drive motors, photovoltaic wind power motors, energy-saving servo motors, and new energy power equipment motors. As the core strategic component of new energy motor systems, permanent magnet steel adopts high-purity rare earth raw materials and advanced sintering and grain boundary diffusion technology, with ultra-high magnetic energy product, high temperature resistance, low temperature demagnetization resistance, and high stability performance, which is the key to realize high efficiency, energy saving, lightweight, and high power density of new energy motors. Compared with traditional motor magnets, new energy permanent magnet steel has more stringent performance indicators, dimensional accuracy, and environmental adaptability, meeting the extreme working requirements of new energy equipment under high speed, high load, and complex temperature difference environment.

In terms of performance indicators, new energy motor permanent magnet steel has leading magnetic performance and extreme environmental adaptability. The product adopts high-grade neodymium iron boron materials such as 42SH, 48SH, 52SH, and 55H, with a magnetic energy product of up to 400-550kJ/m³, which can provide strong and stable magnetic field driving force for the motor, effectively improving the motor power density and energy conversion efficiency, and reducing the energy consumption of new energy equipment. The high-temperature resistant series products can withstand the working temperature of 150℃-180℃ for a long time, and will not produce irreversible demagnetization under high-temperature operation and high-current impact of new energy motors. The low-temperature resistant customized version can work stably in the extreme low temperature environment of -40℃, solving the problem of magnetic attenuation of motors in cold regional operation. In addition, the product has excellent anti-electromagnetic interference performance and uniform magnetic field consistency, which can ensure the smooth operation of new energy motors without jitter, noise, and power attenuation.

In terms of process quality and structural performance, new energy motor permanent magnet steel adopts ultra-precision processing technology and strict quality control standards. The products are processed by CNC high-precision cutting, wire cutting, and surface polishing, with dimensional tolerance controlled within ±0.01mm, realizing precise matching with new energy motor stator and rotor structures. The surface is treated with high-grade epoxy resin coating and nickel-copper-nickel composite plating, which has super strong anti-corrosion, anti-rust, and anti-oxidation capabilities, effectively resisting the erosion of vehicle vibration, rainwater, humid air, and industrial oil mist in new energy equipment working environment. The internal grain structure is uniform and dense, with high mechanical strength, strong impact resistance and fatigue resistance, which can adapt to long-term high-speed rotation, frequent start-stop, and vibration working conditions of new energy motors, with stable performance and no failure throughout the service life of the motor.
