What is The Application Of Neodymium Magnets?

2019-09-10 16:57:29

Today we are talking about the application of neodymium magnets. What's the application of Neodymium magnets? Which one is used more?

 Neodymium magnets can be widely used in motor, engine, voice coil motor, magnetic resonance imaging instrument, communication, control instrument, audio equipment and so on.

Electro-acoustic sound accounts for 32%, magnetizer 21%, motor and sensor 31%, magnetic coupling and magnetic separator 9%, voice coil motor and watt-hour meter 5%, other 2%. Its main application area is VCM (voice coil motor). At present, about half of sintered Neodymium magnets produced abroad are used in VCM. In addition to VCM, motors and generators are widely used. With the development of automotive industry, the demand for Neodymium magnets in this field will increase greatly in the future. The market potential of rare earth permanent magnet motors is huge, which has not been fully developed in China. At present, the rare earth permanent magnet motor has about 2 million kW, which is only 0.5% of the total capacity of 400 million kW of all kinds of motors. If 50% of the old J-JO and J2-JO2 series motors, or 100 million kW, are replaced by rare earth efficient energy-saving motors, about 50,000 tons of high-performance sintered Neodymium magnets will be required. The use of rare earth permanent magnet high efficiency motor can save energy by 15%-20% and reduce the weight of motor by more than 20%. Rare earth permanent magnet high efficiency motor has been listed as the key project of "rare earth application engineering" of Ministry of Science and Technology.

Its applications can be divided into the following categories in terms of physical principles:

1. Electrical and mechanical energy conversion, such as motor, speaker, VCM voice coil motor, etc.

2. Conversion of mechanical energy and electric energy, such as generators, receivers, measuring instruments, etc.

3. Mechanical energy and mechanical energy, such as magnetic separation, magnetic levitation, magnetic transmission, magnetic suspension sucker, etc.

4. Utilize the physical effects of magnetic field, such as magnetic resonance, magnetic wax removal, magnetic oil saving, etc.

The applications of Neodymium magnets are as follows:

Electro-acoustic field: loudspeaker, receiver, microphone, alarm, stage sound, car sound, etc.

Electronic appliances: permanent magnet vacuum circuit breaker, magnetic retaining relay, watt-hour meter, water meter, microphone, reed, sensor, etc.

Motor field: VCM, CDDVD-ROM, generator, motor, servo motor, permanent magnet motor, micro motor, motor, vibration motor, etc.

Mechanical equipment: magnetic separation, magnetic separator, magnetic suspension, magnetic machinery, magnetic pump, etc.

Medical care: nuclear magnetic resonance instrument, medical equipment, magnetic health care products, magnetized fuel saver, etc.

Other industries: magnetized wax preventer, pipe descaling device, magnetic fixture, automatic mahjong machine, magnetic lock, door and window magnetism, box and bag magnetism, leather magnetism, toy magnetism, tool magnetism, craft gift packaging, etc.
