Sintered NdFeB magnetic function and application of wind turbines

Is an NdFeB magnet and the magnet is generally the same, and its excellent magnetic function called " Magneto ." NdFeB sintered NdFeB and bonded NdFeB divided . Sintered NdFeB corrosive , the surface to be coated , usually zinc, nickel, zinc receiver magnet environmental , environmental nickel, nickel-copper- nickel, nickel- copper-nickel and other environmentally friendly ; each direction has bonded NdFeB magnetic , corrosion-resistant .

Sintered ndfeb magnets magnetic material has excellent function, have been widely used in many fields of electronic magnetic separator magnetic , electrical machinery, medical equipment, toys, packaging , hardware, machinery , aerospace and other , more common use of the product with a permanent motors , speakers, magnetic separator, computer disk drives, magnetic resonance imaging device surface.

Permanent magnet wind generator with high magnetic properties of sintered NdFeB magnets, coercivity sufficiently high temperature to avoid loss of field magnets . The life of the magnet depends on the material and surface -treated substrate corrosion . NdFeB magnets corrosion should start from the manufacturer .

Work environment is very harsh wind generator , it must be able to withstand heat, cold , wind , humidity and even salt spray test. Design life of the wind turbine is generally two years. At present, both small wind turbine or a megawatt -class wind turbines are made of sintered permanent magnet NdFeB . Therefore, the choice of NdFeB magnetic parameters , as well as the requirements for corrosion resistance magnet is very important .
