日本住友金属成功地开发了一种资源节约型高强度无取向电工钢SXRC,这种电工钢是通过固溶铌适度抑制位错的合并对消而得到一种特殊的微观组织,因此兼具很高的力学性能和磁性,特别适用于HEV、EV驱动电机转子。而且,不使用昂贵的镍就可以达到期望的强度,合金成本可控,是一种优越的资源节约型产品。 Sumitomo metal industries ltd of Japan successfully developed a type of high strength non-orientation electrical steel SXRC of resources-saving.The steel has both high mechanical performance and good magnetic property thanks to the special microstructure produced by the formation of Nb solid solution serving to appropriately inhibit the combination and cancellation of dislocations.The material is,in particular,suitable for manufacturing rotors of HEV and EV driving motors.Besides,expected streng... 

基于简化的取向硅钢片模型,系统地对不同的交流激励下的硅钢叠片内铁损、交链磁通和空气中指定位置的法向漏磁的分布进行了\"单片级\"的测量,并建立了相应的硅钢叠片级问题的三维有限元分析模型,进行了大规模的数值计算分析。模型实验和数值分析的结果表明垂直进入硅钢片的漏磁通和损耗呈现浅透入的特点,在硅钢片内引起的涡流损耗在总铁损中占据了\"举足轻重\"的份额。用电磁场有限元分析软件MagNet瞬态场时步法计算结果与测量结果相吻合,说明本文方法研究复杂的硅钢叠片问题的有效性。 The measurement and 3D finite element analysis of the iron loss,interlinkage flux inside the laminated silicon steel sheets and the magnetic flux densities at the specified positions are carried out based on a verifying silicon steel sheet model.The modeling results show that the leakage flux vertically through the silicon steel sheets has the peculiarity of shin effect,and the eddy current loss caused by the AC leakage flux is a significant component of the total iron loss.The calculated result...
