What are the types and applications of permanent magnet materials

2022-01-04 15:17:49     

Permanent magnetic materials are also called hard magnetic materials, which means that after magnetic materials are magnetized in some external magnetic fields, they can preserve their strong magnetism for a very long period of time and have high coercivity. Using this characteristic, permanent magnet materials are widely used in many industries such as energy, information and communication, transportation, computers, and medical equipment.

Rare earths seem to have nothing to do with smart phones. In fact, they are used in acoustics, autofocus, ringing, sensors, etc. A smart phone uses more than 10 rare earth "magnets"-neodymium iron boron permanent magnets; manufacturing one New electric vehicles can even require nearly a hundred rare earth permanent magnets; the core material of direct drive permanent magnet wind turbines is neodymium iron boron permanent magnets. According to the calculation by technicians, a 1.5WM direct drive uses neodymium iron boron permanent magnets to reach 1.2 Tons; during the "Thirteenth Five-Year Plan" period, the total scale of urban rail transit planned lines is 7305.3 kilometers. If all permanent magnet traction systems are used, approximately 1,827 tons of NdFeB will be needed. The total demand for NdFeB in my country's rail transit is about 4,577 tons; The industrial robot market is constantly expanding. The core components of industrial robots are controllers, permanent magnet synchronous servo motors, and reducers. To manufacture a 165kg welding robot requires 25 kilograms of high-performance neodymium iron boron.
