Generally, when armature current is flowing, magnetic saturation takes place due to the influence from armature reaction flux, and torque linearity is impaired [10].
通常，当电枢电流流过时，由于受电枢反应磁通的影响，电机磁路会出现饱和，转矩的线性性被破坏。

The above principle suggests that the gap flux and the voltage induced in armature winding of HSY can be controlled adequately and continuously by varying dc field current.
上述原理表明，通过改变直流励磁电流，可以连续地控制HSY 的气隙磁通和绕组感应电压。

With zero field current, armature back yoke flux density is 1.2 t.
