Abstract

Magnetic energy loss P of soft magnetic laminations like SiFe sheets tends to be expressed through an integral over the power product H · dB/dt. Already in earlier papers, we stressed that distinctions are needed for the quantities H and B. However, they are not considered in practically consistent ways, in the so far literature. Here, we discuss these distinctions in closer ways, comparing loss determination by calculation and measurement, respectively. A physically consistent procedure is described for the determination of loss and magnetization power functions through measurement of bi-located quantities H S and B C (S surface, C cross section). On the other hand, it is concluded that corresponding quantitative calculations-based on co-located quantities H and B-are impeded by the high amount of technological parameters of modern steel products. For example, they result from chemical additions, and-in particular-also from specific technologies of rolling, annealing, coating or scribing.

电工钢的铁损耗和瞬时磁化功率函数的计算与测量。
软磁片(如SiFe片)的磁能损失P倾向于通过功率积H·dB/dt的积分来表示。在早期的论文中,我们已经强调了量H和b的区别是必要的。然而,在迄今为止的文献中,它们并没有以实际一致的方式考虑。在这里,我们以更密切的方式讨论这些区别,分别比较通过计算和测量确定的损失。描述了一个物理上一致的过程,通过测量双位置量hs和bc (S表面,C截面)来确定损耗和磁化功率函数。另一方面,现代钢铁产品的大量工艺参数阻碍了基于H和b共存量的相应定量计算。例如,它们是由化学添加剂产生的,特别是由轧制、退火、涂层或划线等特定技术产生的。
