摘要
分析了纳米晶Fe72.5Cu1Nb1.5Mo1.5V1Si13.5B9合金在Bm=0.05T^1.0T、f=20kHz^1000kHz范围内的铁损,以及f=0.5kHz^1000kHz范围内的幅值磁导率行为。主要阐述了铁损与f和Bm的关系,以及在固定的Bmf值情况下,给出铁损大小估算的关系式和合金的频散行为。
The core loss behavior of nanocrystalline alloy Fe72.5 Cu1 Nb1.5 Mo1.5 V1 Si13.5 B9 under the condition of Bm =0.05T～ 1.0T and f = 20kHz ～ 1000kHz and complicated permeability while f = 0.5kHz ～1000kHz were discussed in this paper. In addition, the relationship between care loss and f and Bm and the dispersive character of permeability were also investigated.
