As the third generation of rare earth permanent magnet materials, NdFeB magnets have high performance and are widely used in energy, transportation, machinery, medical, IT, microwave, home appliances, aerospace technology and other industries, especially as represented by information technology. The development of the knowledge economy continues to bring new uses to functional materials such as the rare earth permanent magnet NdFeB industry, which brings broader market prospects to the NdFeB industry. NdFeB magnets have been widely used in many fields, especially in modern high-tech fields.
1. Electromechanical applications of NdFeB market
The emergence of rare earth permanent magnets means that the field of motors will cause revolutionary changes. This is because rare earth permanent magnets have no excitation losses and do not generate heat. Motors made with them have many advantages. Because the rare earth permanent magnet motor does not have an excitation coil and an iron core, the magnet volume occupies a smaller space than the original magnetic field pole, has no loss, and does not generate heat. Therefore, in order to obtain the same output power and the size of the complete machine, the weight can be reduced by more than 30%, or the same volume. , weight, output power is more than 50% greater
2. NdFeB market applications: speakers and headphones
Speakers and headphones are traditional applications of permanent magnets. Nowadays, some high-end speakers use NdFeB.
3. Microwave devices for NdFeB market applications
In the microwave field, microwave tubes, milliwave tube generators or amplifiers need to stabilize the magnetic field, in which rare earth permanent magnets mainly play a role in gathering electron motion.
4. Magnetic separator for NdFeB market applications
Generally, there are two types of magnetic separators: permanent magnet type and electromagnetic type. In the past, the magnets of permanent magnet magnetic separators were mostly ferrite. After the emergence of rare earth permanent magnets, various models and types of permanent magnet magnetic separators were designed and manufactured. Machines, especially in medium and high magnetic field magnetic separators, must use rare earth permanent magnets.
