## The Difference Between Rotating Field And

Rotating field has field winding on the rotor and armature in the stator. Rotating armature has armature in the rotor and field winding in the stator. Rotating armature is used only for DC generator since it is impossible to get DC output when the armature is stationary. Rotating field is advantageous for AC generator specially in the plant with high voltage level like 11kV and up. References: Feedback
