Neodymium Magnet Assembly

Today I will tell you about the application fields of NdFeB magnets. What are the application fields of NdFeB magnets? Which one is used more?
Neodymium Magnet Assembly can be widely used in motors, engines, voice coil motors, magnetic resonance imaging instruments, communications, control instruments, audio equipment, etc. Electroacoustics account for 32%, magnetizers account for 21%, motors and sensors account for 31% , magnetic coupling shaft and magnetic separator accounted for 9%, voice coil motor and watt-hour meter accounted for 5%, and others accounted for 2%.
Its main application field is VCM (Voice Coil Motor). At present, about half of the sintered NdFeB magnets produced abroad are used in VCM. Except for VCM, the most widely used fields are motors and generators. With the development of the automobile industry In the future, the demand for Neodymium Magnet Assembly s in this field will increase greatly. The rare permanent magnet motor market has great potential, and it is a huge field that has not been fully developed in China. At present, the rare earth permanent magnet motor has about 2 million kW, which is only equivalent to 0.5% of the total capacity of various motors of 400 million kW. If 50% of the old J-JO and J2-JO2 series motors are replaced by rare earth high-efficiency and energy-saving motors, that is, 100 million kW, about 50,000 tons of high-performance sintered NdFeB magnets are required. The use of rare earth permanent magnet high-efficiency motor can save energy by 15% to 20%, and reduce the weight of the motor by more than 20%. The rare earth permanent magnet high-efficiency motor has been listed as a key project of the "Rare Earth Application Project" by the Ministry of Science and Technology.

Application of Neodymium Magnet Assembly can be divided into the following categories from the physical principle:
1. Electric energy mechanical energy conversion, such as: motors, speakers, VCM voice coil motors, etc.;
2. Mechanical energy and electrical energy conversion, such as: generators, receivers, measuring instruments, etc.;
3. Mechanical energy Mechanical energy, such as: magnetic separation, magnetic levitation, magnetic transmission, magnetic suspension magnetic sucker, etc.;
4. Using the physical effects of magnetic fields, such as: magnetic resonance, magnetization wax removal, magnetization fuel saving, etc.;

The application range of Neodymium Magnet Assembly is as follows:
Electroacoustic field: speakers, receivers, microphones, alarms, stage audio, car audio, etc.
Electronic appliances: permanent magnet mechanism vacuum circuit breaker, magnetic latching relay, watt-hour meter, water meter, sound meter, reed switch, sensor, etc.
Motor field: VCM, CDDVD-ROM, generators, motors, servo motors, permanent magnet motors, micro motors, vibration motors, etc.
Mechanical equipment: magnetic separation, magnetic separator, magnetic crane, magnetic machinery, magnetic pump, etc.
