Specifically, NdFeB magnets can be used in the rotor section of a generator set. Ndfeb magnets have higher magnetic energy accumulation and thermal stability than conventional materials with low energy accumulation. Ndfeb magnets demagnetize at high temperatures (>80°C), and attention should be paid to its operating temperature range. This means that with the same rotor size, higher flux density and higher output power can be obtained by using NdFeB magnets. In addition, because NdFeB magnets have less hysteresis loss and eddy current loss, the output power of the generator set is more stable and reliable.
NdFeB magnets in wind power generation improve the performance and efficiency of the whole machine, achieving greater energy utilization and less energy waste.
NdFeB is prone to oxidation and usually requires zinc, nickel or epoxy coatings for enhanced corrosion resistance.
In addition to improving the performance and efficiency of wind turbines, Ndfeb magnets offer other features. High-performance N52 magnets are more costly due to price fluctuations of rare earth elements (neodymium) and process complexity. The cost of NdFeB is strongly influenced by raw materials, but the comprehensive performance makes it economical for high-end applications.
In general, with the continuous progress of technology and the expansion of application scope, it is believed that the application of Ndfeb magnets will be more widely developed and applied in the global energy sector.
