The practical testing of dynamos and motors (1905)
Smith, Charles Frederick, 1873- · Manchester Scientific Pub. Co · leaf 110
series dynamo the entire current flows throughthe field coils, which are connected in series with themain circuit. In this case, an increase of load means anequal increase in the exciting current. The excitation,therefore, depends upon the load and increases with it.The voltage of the dynamo will… … Fig. 29. D Dynamo armature. F Dynamo field windings. R Adjustable resistance for varying the load. A Ammeter for measuring load current. V Voltmeter for measuring dynamo voltage. S Switch for breaking main circuit. 96 THE SERIES DYNAMO. Connections.—See that the field windings are connectedso that…
