Application and cutting of magnet NdFeB

The popularity of new energy vehicles has injected new vitality into the members of the industrial chain.

Whether it is a traditional fuel vehicle or a new energy vehicle, the introduction of high-efficiency and energy-saving micro motor is one of the key paths to achieve energy saving, lightweight and small-scale high-performance.


According to the 2012 NdFeB depth report of rare earth permanent magnet industry, the efficiency of motors using bonded NdFeB magnets is 8% to 50% higher than that of ordinary motors, the power consumption is reduced by more than 10%, and the volume and weight can be reduced by more than 30%.

However, more than 30 years ago, bonded NdFeB was only an "academic term" existing in the laboratory in China. But a group of people foresaw its potential.

Neodymium iron boron (NdFeB), the third generation rare earth permanent magnet, is a kind of permanent magnet with strong neutral energy. Its potential magnetic properties are extremely high, and it can absorb a weight that is thousands of times its own weight. The mechanical properties of NdFeB magnets are better than those of other magnets, and they are easier to cut, drill and process complex shapes. Its disadvantages are poor temperature performance, large magnetic loss under high temperature and low working temperature. It is generally about 80 ° C. after special treatment, its working temperature can be as high as 200 ° C. Because the material contains a large amount of neodymium and iron, it is easy to rust. Therefore, the NdFeB magnet must be coated. It can be electroplated with nickel (Ni), zinc (Zn), gold (AU), chromium (CR), epoxy resin (epoxy), etc. Neodymium iron boron (NdFeB), the third generation rare earth permanent magnet, is a kind of permanent magnet with strong neutral energy. Its potential magnetic properties are extremely high, and it can absorb a weight that is thousands of times its own weight. The mechanical properties of NdFeB magnets are better than those of other magnets, and they are easier to cut, drill and process complex shapes. Its disadvantages are poor temperature performance, large magnetic loss under high temperature and low working temperature. It is generally about 80 ° C. after special treatment, its working temperature can be as high as 200 ° C. Because the material contains a large amount of neodymium and iron, it is easy to rust. Therefore, the NdFeB magnet must be coated. It can be electroplated with nickel (Ni), zinc (Zn), gold (AU), chromium (CR), epoxy resin (epoxy), etc.
