quality Permanent Ferrite Magnet & Sintered Ferrite Magnet manufacturer

Against the backdrop of increasingly strict global energy efficiency standards, permanent ferrite magnets are becoming the preferred magnetic material for energy conservation and consumption reduction in fields such as home appliances, automobiles, and industrial motors, thanks to their triple advantages of "low cost, high efficiency, and green manufacturing". 1. Material level: Performance improvement leads to direct energy conservation High residual magnetism + high coercive force The latest wet-pressed ferrite magnetic tiles have Br≥ 4.2kG and Hcj≥ 4.0kOe, which can output the same torque at a lower current. The copper loss and iron loss of the motor decrease by 8% to 15% simultaneously. Low-temperature sintering process The patented formula and secondary sintering at a low temperature of 1180 ℃ refine the grain structure, reduce eddy current loss, and further lower the energy consumption per ton of magnetic tiles by 5%.   2.Device level: Energy-saving of variable-frequency friendly amplification system Wide speed range and high efficiency The demagnetization inflection point of the high coercive force magnetic tile is flat, supporting the stable operation of DC inverter motors at a low frequency of 1 Hz, avoiding the waste of "a big horse pulling a small cart". The energy efficiency ratio of inverter air conditioners has thus increased by 20%. High-temperature stability The Curie temperature is 450 ℃, and the magnetic flux attenuation under the operating conditions of -30 ℃ to 120 ℃ is less than 3%, ensuring that the compressor and fan can still maintain high-efficiency zone operation under extreme weather conditions. Both volume and weight have decreased When the magnetic energy product is increased by 10%, the motor length can be shortened by 10% to 15%, directly reducing the usage of copper wires and silicon steel sheets, thus achieving "secondary energy conservation". 3.System Level: Waste Heat Utilization and Energy Conservation throughout the Entire Life Cycle Waste heat recovery of double-layer roller kiln The latest sintering kiln has led the 250 ℃ hot air from the cooling section back to the preheating and drying section, replacing electric heating. The daily production capacity of a single kiln is 20 tons, and the unit energy consumption has been reduced to 0.70 kWh/kg, saving 30% of electricity compared to traditional kilns. A super-long lifespan of 30 years Ferrite is corrosion-resistant and anti-oxidation, with a demagnetization rate of less than 3% for 30 years. It avoids the system efficiency decline caused by demagnetization or corrosion of rare earth magnets and does not require additional energy consumption compensation throughout its entire life cycle. From the perspective of the entire chain of "materials - devices - systems", permanent ferrite magnets, with their low raw material costs, low manufacturing energy consumption, low operating losses, and high reliable lifespan, provide scalable and replicable energy-saving solutions for the three major energy-consuming terminals of home appliances, automobiles, and industry. Driven by the "dual carbon" goals, ferrite permanent magnets are not only transitional substitutes but also long-term sustainable green magnetic cores.

When I turned on the smart door lock after work, the air conditioner had already started in advance. The refrigerator quietly keeps fruits and vegetables fresh. The sweeping robot shuttles through the living room. The car starts with a single button and the wipers move with the rain - behind these seemingly ordinary moments, there is an unremarkable small gray-black magnet: a permanent ferrite magnet. With its hard-core features of "affordable price, stable performance, high-temperature resistance and corrosion resistance", it has quietly integrated into every "functional chain" of modern life. I. Home Appliance Scenario: Making Comfort "Silent" Inverter air conditioning compressor The wet-pressed ferrite magnetic tiles form the motor rotor, and in combination with the frequency conversion algorithm, enable the air conditioner to operate smoothly at a low frequency of 1 Hz, saving 15% to 20% of electricity throughout the year. Refrigerator, washing machine, dishwasher The ferrite magnetic rings in the drainage pump, fan motor and detergent dispenser make it possible for the refrigerator to achieve low-noise cooling at 38 dB(A) and for the dishwasher to precisely dispensed detergent. Sweeping robot The virtual wall magnetic strips and wheel speed Hall magnetic rings achieve path planning and restricted area isolation, ensuring that the "lazy person's magic tool" does not cause any trouble. Ii. Automotive Scenario: The "Magnet Army" of a Single Vehicle Economy cars are equipped with over 20 small motors, while luxury cars have nearly 70. Start motor, electric seat, ABS, wiper, electric rearview mirror... Almost every motor has a ferrite tile. The global demand for ferrite permanent magnets for automobiles is expected to reach 450,000 tons in 2023, with a compound annual growth rate of 5% over five years. Against the backdrop of high oil prices and rare earth prices, ferrite continues to replace some rare earth permanent magnets with its "cost performance + temperature resistance". Iii. Consumer Electronics and Office Hard disk head positioning, notebook computer fans, laser printer paper feeding mechanisms, and electric toothbrush micro-motors - ferrite magnets provide "centimeter-level" precise movements with "millimeter-level" dimensions, ensuring the thinness and long battery life of the devices. Iv. Industry and Energy High-performance ferrite tiles are extensively used in photovoltaic inverters, energy storage converters, charging pile fans, and factory manipulator shaft drive motors to achieve the dual goals of "high energy efficiency and low cost". V. Future Outlook Process upgrade: Microwave sintering and nano-doping are increasing the magnetic energy product of ferrite by another 10%, further expanding its share in high-end motors. Green cycle: The ferrite raw materials are Fe₂O₃ and SrCO₃, which are abundant in source and do not require rare earths, in line with the sustainable route under the "dual carbon" background. From the grinding motor of the coffee machine in the early morning to the silent motor of the bedside fan at night, permanent ferrite magnets exist like air but are rarely seen. It is precisely this "unsung hero" who has made every "start", "speed regulation" and "silence" of modern life possible, and will continue to support the wave of electrification and intelligence of all things with lower costs and higher efficiency in the future.

When an inverter air conditioner starts to operate, the moment you press the remote control, the first thing to activate is not the fan visible to the naked eye, but the compressor motor hidden inside the outdoor unit. Permanent ferrite magnetic tiles are embedded in the rotor of this motor. They act like an "invisible commander", determining the cooling speed, energy consumption and noise level of the air conditioner. Compressor motor rotor Inverter air conditioners generally use DC brushless motors as the power source of the compressor, and the rotor is composed of multiple high-performance wet-pressed ferrite permanent magnet tiles spliced together. The fixed magnetic field generated by the magnetic tiles interacts with the alternating magnetic field of the stator winding, driving the rotor to rotate and thereby driving the compressor piston to complete the refrigerant circulation. Indoor and outdoor fan motors Whether it is an axial fan or a cross-flow fan, their driving motors also adopt permanent ferrite magnetic rings. Compared with traditional induction motors, the permanent magnet solution can increase efficiency by more than 10% while reducing noise by 3 to 5 dB(A). Electronic expansion valve and stepper motor The micro stepping motor is also equipped with injection-molded ferrite multi-pole magnetic rings inside, which are used to precisely regulate the refrigerant flow and achieve a temperature control accuracy of 0.1℃. Energy conservation: The high residual magnetism (Br≥ 4.2kG) and high intrinsic coercive force (Hcj≥ 4.0kOe) of permanent ferrite magnetic tiles enable the motor to still output high torque at low speeds. Combined with frequency conversion algorithms, the annual energy consumption efficiency (APF) can be increased by 15% to 20%, helping air conditioners easily meet the new national standard level 1 energy efficiency. After the magnetic tile waveform undergoes laser micro-grinding, the cogging torque decreases by 30%, the vibration of the compressor operation is significantly reduced, and the noise of the indoor unit can be as low as 18 dB(A), almost imperceptible. The Curie temperature of ferrite can reach up to 450 ℃. It will not demagnetize even when working for a long time in an environment ranging from -30 ℃ to 120 ℃, ensuring the stable operation of the air conditioner in both extremely cold and hot weather. From fixed-frequency to variable-frequency, from energy-saving to quiet, although the permanent ferrite magnetic tiles are hidden deep in the compressor, they dominate every "breath" of the air conditioner. It not only makes the electricity bill thinner but also makes summer nights quieter - this is precisely the irreplaceable value of permanent ferrite magnets when air conditioners are in operation.
