e whenwound in this way, the spark on the commutator is hardly per-ceptible. In fig. 452, an ingenious mode of connecting the coilsto the commutator is shown, which is designed for use inmachines of high electro-motive force, such as are used for arc-lighting circuits. In machines having… … Fig. 451. coils, distinguished by the white and black lines respectively,which alternate throughout the circumference. These are con-nected to alternate plates of the commutator in the mannershown. It is obviously impossible to short circuit any coil byconnecting adjacent sections of the…
