英语语法分析

Magnetomotive forces in the HSY field system are produced by combined action of permanent magnets and dc field winding.

HS y场系统中的磁动势是由永磁和直流励磁相互作用而产生。

The method compensates the stator current in the fault state in order to keep the magnetomotive force as that in normal state.

该方法以故障前后定子侧产生恒定磁动势为原则，对定子侧电流进行补偿。

This field force is called magnetomotive force (MMF), and is very much analogous to electromotive force (e) in an electric circuit.

这个场力被称作磁动力(mmf)，非常类似于电路中的电动里(E)。
