钕铁硼永磁体是目前综合素质最为优异永磁体。钕铁硼永磁体是磁性参数优异、性价比较高、综合素质最为优异的永磁体，使用烧结钕铁硼磁体能够大幅降低磁材使用量、缩小电机体积和重量，大幅提升电能-机械能转化效率，相对于普通永磁体能效提升 10%-15%以上。

Neodymium-iron-boron permanent magnet is the most excellent comprehensive quality of permanent magnet. ND-FE-B permanent magnet is the most excellent one with excellent magnetic parameters, high performance-price ratio and comprehensive quality. The use of sintered ND-FE-B permanent magnet can greatly reduce the amount of magnetic material used, and reduce the volume and weight of the motor, greatly improve the electrical energy-mechanical energy conversion efficiency, compared with ordinary permanent magnet energy efficiency increase of 10% -15% .
