A DC Compound Motor connects the armature and fields windings in a shunt and a series combination to give it characteristics of both a shunt and a series DC motor. This motor is utilized when both a high starting torque and excellent speed regulation is needed. The DC Compound Motor can be connected in two arrangements cumulatively or differentially. Cumulative compound motors connect the series field to aid the shunt field, which provides higher starting torque but less speed regulation. Differential DC Compound Motor has good speed regulation and is typically operated at constant speed.
