High-performance NdFeB permanent magnet material industry application market
High-performance NdFeB permanent magnet materials are mainly used in high-tech products, such as motors, compressors, and sensors. Specific application fields include: consumer electronics products, traditional automobiles and other traditional fields, as well as emerging fields such as new energy vehicles, wind power generation, energy conservation and environmental protection. .
On the one hand, traditional application fields have a relatively high penetration rate in daily life, especially mobile phones, computers and other electronic products are widely used and develop steadily; on the other hand, emerging application fields such as new energy vehicles and wind power generation are in line with energy conservation, emission reduction, and environmental protection. In the fields of new energy vehicles, wind power generation, air conditioners, and industrial motors, new materials and new processes are used. As a new material, NdFeB is affected and driven by various factors. The industry application field continues to expand. The NdFeB permanent magnet material The requirements are getting higher and higher, which promotes the development of the NdFeB industry in the direction of refinement, personalization and customization.
1. Automobile industry
1) Traditional automotive field
In the automobile manufacturing process, high-performance NdFeB is widely used in important parts of automobile micro-special motors such as electric power steering system (EPS), anti-lock braking system (ABS), audio, automobile oil pump and ignition coil, which have high requirements on motor performance. permanent magnet material.
2) New energy vehicle field
There are four major types of motors in the field of new energy vehicles: DC motors, induction motors (asynchronous motors), switched reluctance motors and permanent magnet motors. At present, most new energy vehicle drive motors use permanent magnet motors, and their penetration rate shows a trend of increasing year by year. As the power source of new energy vehicles, permanent magnet motors have the characteristics of high energy density, reliable operation, and good speed regulation performance. Compared with other types of motors, they can provide greater power output with the same mass and volume. Ideal motor type for energy vehicles.
2. Energy-saving home appliances
With the continuous improvement of energy efficiency standards and the concept of low-carbon life deeply rooted in the hearts of the people, green and energy-saving inverter appliances have gradually become a consumer trend in the home appliance market. Inverter household appliances mainly include inverter air conditioners, inverter refrigerators, inverter washing machines and other household appliances. Compared with traditional fixed-frequency household appliances, inverter appliances have the advantages of low noise, energy saving, and long life. High-performance NdFeB permanent magnet materials have gradually replaced ferrite permanent magnet materials due to their better performance, and have become the first choice for permanent magnet motor magnets for frequency conversion appliances.
3. Wind power generation
In the field of new energy and energy saving and environmental protection industries, wind power generation is one of the main application fields of high-performance NdFeB permanent magnet materials.
There are three types of wind turbines mainly used in the field of wind power generation: doubly-fed wind turbines, semi-direct drive generators and direct drive generators. Most direct-drive wind turbines are permanent magnet synchronous generators, which tend to gradually replace double-fed wind turbines due to their advantages such as low maintenance costs and high system efficiency. In the future, with the large-scale generation of units, especially the rapid increase in the proportion of offshore wind power installed capacity, the market share of direct-drive permanent magnet motors will increase.
4. Consumer Electronics
NdFeB permanent magnet materials are widely used in acoustic systems such as mobile phone speakers, receivers, and camera voice coils due to their high magnetic energy product and high coercive force. Motors (VCM), mobile phone high-end vibration motors, TWS earphones and many other consumer electronics components. In recent years, consumer electronics products represented by smartphones and wearable devices have developed rapidly and become the main growth point of the consumer electronics industry.
5. Industrial motors
Permanent magnet motors have the characteristics of simple structure, small size, high reliability, low loss and high efficiency, and are widely used in various fields such as industrial and agricultural production, aerospace, automobiles, home appliances, medical equipment, and electronic products. The high-end products in the magneto can significantly reduce power consumption, have higher unit power and can realize precise control, and are the main choice of high-end motors. With the increasing application types of industrial motors, the market demand for high-performance NdFeB magnets will continue to grow.
