This text expanded the magnetoelastic stability issue of current - carrying component from coil , pole piece to thin current - carrying plates , and used special function to differentiate the critical state of losing magnetoelastic steady , the number value of getting the relevant parameter is solved . the text derives and provides the magnetoelastic movement equation of thin current - carrying plates , the geometry equations and the physics equations , the expression formula of lorent ’ s force , electro dynamics equation through the theory at first 本文將載流構件磁彈性穩定問題由線圈、桿件拓展到載流薄板,并引入特殊函數判別磁彈性穩定問題的失穩臨界狀態,得到了相關參量的數值關系。首先通過理論推導給出了載流薄板的磁彈性動力學方程,幾何與物理方程,洛侖茲力的表達式,電動力學方程。

Ratio of the pole spacing to the bore diameter of the pole pieces 極靴的間距與孔徑比

A pair of capacitive rings attached to the respective pole piece is used to detect movement of the coil . 兩個分別附在各自極靴上的電容環被用來探測線圈的運動。
