NdFeB magnet applications

- Nov 14, 2017 -

Application in microwave communication technology:

In the radar technology, satellite communications, remote telemetry technology, electronic tracking, electronic warfare technology needs to be used, magnetron, magnetron traveling wave tube, cathode ray tube, circulator and so on to use neodymium iron boron.

 

Application in Electrical Engineering

One third of the output of rare earth permanent magnetic materials used to manufacture a variety of permanent magnet motor, permanent magnet motor has the advantage of saving copper, power, light weight, small size, high specific power. Electric bicycle motors, computer-driven motors, lathes, such as the line speed and speed measurement motor, elevator traction motor, mahjong motor, refrigerator air conditioning motor, wind motor, motor vehicle motor and so a wide range of applications.

 

In the electro-acoustic device applications:

Such as speakers (speakers), microphones, hearing aids, stereo headphones (MP3, MP4), telephone receivers and electro-acoustic sensors and more.

 

In magnetic mechanical engineering applications:

Magnetic machinery, including magnetic drives, magnetic gears, magnetic brakes, magnetic fixtures, magnetic salvage equipment, magnetic bearings, magnetic pumps, magnetic valves, magnetic door, magnetic locks and permanent lifting, permanent magnet handling machines.

 

Application in transportation:

The principle of making use of same-sex repulsion is called maglev train; modern luxury sedan need to use 15-70 permanent magnet devices, such as: windshield wiper motor, pump motor, window motor, door lock motor, fog motor, Automatic steam control, starting motor.

 

Magnetic separation technology in the application:

The technique of separating the ferromagnetic material from the non-ferromagnetic material by a magnetic method is called a magnetic separation technique. Magnetic separation technology in the beneficiation, coal preparation, raw material processing, water treatment, garbage disposal and in the medical, chemical and food industries have been widely used.

 

Application in magnetization technology:

The use of magnetic field of the material magnetization, changing the bonding state and nature of the material being magnetized; or change the atomic and electronic state, and promote the chemical reaction of the material and combustion of the fuel; or change the crystalline form or freezing point of the material, this technique is called Magnetization technology. Magnetizer, fuel-saving car in the car, oil wax prevention in petroleum exploitation and so on.

 

Applications in magnetic therapy and fitness equipment:

Such as magnetic cups, magnetic ball, magnetic machine, magnetic shoes, magnetic therapy cap, magnetic bracelets, necklaces, etc., as well as the rapid development in recent years, medical equipment, magnetic resonance imaging (MRI) - 4 tons, imagine each hospital in China with an MRI NdFeB dosage should be how much!

 

In short, since the invention of NdFeB in 1983 every year since the emergence of new areas of application, the annual increase of 30% or more, the application prospect is very broad.
