consumed is the same; the only difference being that in the one caseall the energy taken from the line is expended in driving the motor whilein the other case only one half is utilized for power, the other half beingdissipated in the resistance. Speed regulation by armature resistanceonly is… … Fig. 762.—Cutler-Hammer compound speed regulator with no voltage and overload release;regulation by combined armature and shunt field resistance, designed to both decrease andincrease the speed of a motor. Speed reduction is accomplished by inserting resistance inthe armature circuit, the maximum…
