Nd-Fe-B(系列)永磁体(BH)_(max)的估算系数K

EVALUATION COEFFICIENT K OF Nd-Fe-B PERMANENTMAGETIC BODY(BH)_(max)

本文对隆起度γ=1/4进行了讨论,并由β_γ与估算系数K计算最大磁能积(BH)_(max)(KJ/m^3)。以日本、美国、西德Nd-Fe-B(系列)永磁体各种牌号的磁性参数为计算依据确定了K值。对研究和生产有较大的实用价值。

The protuberance r=1/4 is discussed in this paper. The maximum enery product (BH)_(max)(KJ/m^3) by B_r and evaluation coefficient K is calculated. The value of K is defermined according to magnetic parameter of Nd-Fe-B permanet magnetic body. They are Japan, America, and German tradmark. It's more valuable for reaseareh and production.
