查询词典 synchronous

So, it is very difficult to monitor and protect the rotating rectifier. This paper theoretically analyses the armature current and magnetomotive force in AC exciter of brushless synchronous machine with rotating rectifier. Under the normal or fault conditions of rotating rectifier, the mathematical expressions of the armature current, the m.m.f and induced electromotive force are approached.
