The elements of dynamic electricity and magnetism (1903)
Atkinson, Philip. [from old catalog] · New York, D. Van Nostrand company · leaf 198
rated by Fig. 75, the entirecurrent traverses a single route of low resistance, pass-ing in series through the armature, the field-magnets, THE DYNAMO AND MOTOR, I8 and the external circuit; so that any variation of resist-ance, at any point, affects the entire series equally. In the shunt method,… … Fig. 76. coarse wire of the external circuit, while a small cur-rent, varying from 1.5^ to 20^ of the entire volume,flows through the shunt, or fine wire with which themagnets are wound, and is employed exclusively toexcite them. If the resistance of the main circuit is increased, thestrength of…
