| 摘 要： | 本文研究了经过纵向磁退火的铁镍钴合金带的铁心损耗,发现P/f-f曲线具有明显的反常行为。用180°畴壁移的反常涡流损耗理论模型做了解释。并提出一些减小损耗的可能途径。

| Abstract: | Investigation has been made on the losses in magnetic cores consisting of strips of iron-nickel-cobalt alloy after annealment in a longitudinal magnetic field. It has been found that the p/f-f curve shows obvious anomalous behaviour. Explanation is given for this behaviour with a Theoretical model of the anomalous eddy current loss caused by the wall displacement in the 180?domains. Possible ways of minimizing the loss are suggested. |
