self-excited circuit 中文意思是什麼
self-excited circuit
解釋
自激電路-
It will exert resistance and damping force to the torque motor armature, so that the dynamic performance, especially the stability, of flapper - nozzle servo - valve can be improved. the self - excited oscillations and noise can be removed. at the same time, as magnetic fluid has a higher magnetic permeability, the efficiency of torque motor magnetic circuit can be improved
由於磁流體具有的較大磁導率和較大的磁化強度,把磁流體添加到伺服閥力矩馬達的工作氣隙中,可提高伺服閥力矩馬達的磁迴路效率,增加伺服閥的阻尼,從而改善噴嘴擋板伺服閥的動態特性,抑制及消除其自激振蕩和噪聲。
