. A text-book of electrical engineering;. Fig. 287 Fig. 288 pitch. In Fig. 285, for example, the wire passes up slot i from back tofront, and then down slot i from front to back, and so on. When this coilis completely wound, we pass to the coil 2, 2 by means of the dotted con-nection at the back end of the armature. The internal pole machine (Fig. 289) is strikingly simple both in prin-ciple and construction, and is the type almost universally adopted. Theexternal and stationary armature is built up of sheet-iron stampings.
