At present, two kinds of materials of high performance neodymium iron boron permanent magnet used in ferrite magnet of inverter air compressor. The lower magnet oxygen permanent magnetic material, but the price is relatively low, the production of medium-low frequency conversion air conditioning, high-performance neodymium iron boron permanent magnetic material is the highest permanent magnetic material, mainly for the production of high-end frequency conversion air conditioning.
Since the magnetic ferrite permanent magnetic material is low, a large amount of space is used to occupy a larger compressor. With the improvement of the performance of the VVAC compressor, its magnetic performance requirements are getting higher and higher. If the ferrite permanent magnetic material is used, will the amount be multiplied? What? Increase, other materials of the motor, such as copper consumption should be significantly increased, not only occupy the space compressor, its low-cost advantage will gradually weaken. Therefore, the trend of miniaturization of air conditioning in the future, the ferrite permanent magnet material of the air conditioning system in the inverter will gradually replace the high-performance neodymium iron boron permanent magnet material.
Magnetic materials and devices are based on the prediction of the Chinese industry association. In the next few years, the proportion of variable frequency air conditioners produced using high-performance neodymium iron boron permanent magnetic materials will rise rapidly, reaching 20, 30, 40, 50, and 60 from 2008 to 2014. <UNK>, 70, 80.
