Shunt excitation

WebShunt excitation: Here the field winding is provided with a large number of turns of thin wire and is excited from a voltage source. The field winding, therefore, has a high resistance … WebExplanation: In compound excitation both shunt and series field are excited. If the two field aid each other (their ampere-turn is additive), the excited is called cumulative compound. The shunt field is much stronger than the series field. The air gap flux increases with armature current.
