What are wound field motors and where are they applied?

WebShunt-Wound Generators In a shunt-wound generator, the field coils consist of many turns of small wire and relatively high field resistance. They are connected in parallel with the load. In other words, they are connected across the output voltage of the armature. DC Machines WebTraditionally dc motors were classified as shunt, series or separately excited. In additions it was common to see motors referred to as compound-wound. There is really no fundamental difference between shunt, series or separately excited dc motors, and the names simply reflect the way in which the field and armature circuits are interconnected. grace co books
