风力发电机铁芯Wind Generator Core SMC

　　铁芯优点SMC Advantages

　　SMC铁芯是以替代传统叠片硅钢片为目的而开发出来的一种新型复合软磁材料，其具有传统硅钢片无法比拟的优势：

　　SMC is developed in order to replace traditional silicon steel sheets, it has below advantages compared with silicon steel sheets:

　　高频下运转铁损损耗很小一一一组成铁芯的每个颗粒表面均包覆着一层绝缘保护膜，产品的电阻率高，可以在很大程度上降低铁芯的涡流损;

　　Low iron losses while running in high frequency:There is an insulating protective frlm on the surface of every particle of the materials to make high electrical resistivity, so the eddy current losses are reduced to a large extent.

　　材料利用率高一一一采用PMI艺成型，材料利用率达95%以上;

　　Raising material utilization: With PM formed, the material utilization is beyond 95%.

　　磁极转换性好一一一不需取向，且能进行三维结构设计;

　　Easy pole shifting: Do not need magnetic orientation, also can be designed in 3D structure.

　　产品发热较小一一一在高频运转条件下，因涡流损耗低工作效能较高，能耗小，发热状况得到明显改善;

　　Low heating:As for the low eddy current losses and high efficiency make the low energy consumption, so heating is improved while motors run in high frequency.

　　公差非常精密一一一产品尺寸完全由模具控制，产品尺寸一致性好外观非常光滑，产品尺寸精度高;

　　Precise tolerance: The dimension is completely controlled by module to make the size precise and surface smooth.

　　电机整体成本降低一一一可加工成三维结构，缩短轴向尺寸，节约线材;

　　Reducing motor cost: SMC cores can be processed in 3D structure to shorten axial size to

　　save wires.

　　磁致伸缩系数较小一一一马达噪音明显降低

　　Lower Magnetostrictive coefficient: Obvious reducing motor noise.
