h3nds of the coil become commutator bars, making the coilcontinuous from one end of the commutator bar to the end)f the diametrically opposite commutator bar.To increase the electro-motive force. The greater the 1044 Steam Engineering field strength, and the higher the speed the greater… … Fig. 43S SEPARATELY AND SELF-EXCITED SERIES DYNAMO. In order to further increase^ the electro-motive forcemore turns or loops of wire must be wound on the arma-ture. A coil of 16 turns as in Fig. 435 will give an electro-motive force 16 times as great as a coil like Pig. 426. Eef-erence to Fig. 436…
