yoke flux

基本解释

Also, the flux density at the back yoke can be found from this flux, and the back yoke cross-section area.
也就是说，导磁机壳的磁通密度可以由该磁通和导磁机壳的截面积计算得到。

On the other hand, resulting flux at the N-side or S-side of the gap is a dc flux circulating through the back yoke.
另一方面，气隙N 极边和S 极边的合成磁通是环绕导磁机壳的直流磁通。
