The application of NdFeB rare earth permanent magnet
Neodymium iron boron magnets (NdFeB) are one of the strongest rare earth permanent magnet types available, and their (BH)max is much larger than that of samarium cobalt magnets. Neodymium iron boron magnets have excellent properties, so they are often the magnet of choice for many applications across a wide range of industries. #NdFeB Strong Magnet#
Let’s take a look at the main uses of NdFeB rare earth permanent magnets:
1. Energy-saving home appliances
The NdFeB permanent magnet material can be used in the inverter compressor in the inverter air conditioner. The air conditioner compressor acts as the core component of the air conditioner. The application of NdFeB magnets will run at different speeds to improve the efficiency, reliability and performance of electrical appliances. Effectively save energy consumption and reduce use costs.
The motor traction machine in the energy-saving elevator will also use NdFeB rare earth permanent magnet materials. The permanent magnet synchronous traction machine adopts high-performance permanent magnet materials and a special motor structure, which has energy saving, environmental protection, low speed, high torque, etc. Features, can greatly reduce the energy consumption of the elevator, and has the effect of energy saving and environmental protection.
2. Wind power generation
Wind power generation is one of the fields that use the largest amount of high-performance NdFeB permanent magnet materials at this stage. It is mainly used for the production of permanent magnet direct drive fans. This kind of equipment has a very simple structure, long service life, low operation and maintenance costs, and higher power generation efficiency than double-fed asynchronous fans. It is more suitable for working in low wind speed environments.
3. Consumer Electronics
Because NdFeB has the characteristics of small size, high magnetic performance, and high cost performance, it conforms to the development trend of consumer electronics products such as miniaturization, light weight, and thinness. It is widely used in consumer electronics components such as cameras and TWS earphones. In the future With the steady growth of the smart consumer electronics market, the demand for it will also increase significantly.
4. Industrial robots
NdFeB magnets are timely and important components of industrial robots. In the field of industrial robots, one of the most common functions of magnets is for motion sensors. In order for motion sensors and other types of sensors to function properly and accurately, they require magnet assemblies to provide stringent parameters and precision.
5. New energy vehicles
Electric vehicles require high torque density, high operational reliability, and good torque control capability for the drive system, which requires high magnetic energy product, high coercive force and high operating temperature for NdFeB. Since energy product and coercive force are opposed to each other, a compromise is required.
6. Other fields
NdFeB rare earth permanent magnet materials are widely used. Neodymium magnets are also used in the medical industry, magnetic levitation, packaging and other fields. Basically, the application of NdFeB magnets can be seen in daily life.
