The three-phase current is taken from three slip-rings connectedto points on the armature separated by 120°. In other respects the machineis identical with a dynamo. (See the left-hand part of Fig. 366.) Thewidth of each coil-side is equal to f of the pole-pitch. If the coil-side bemade equal to | of the pole-pitch, as represented diagrammatically in and 365, the phases are connected as shown on the right-hand side ofFig. 366. The admissibility of interconnecting the three phases in this way can beseen from the vector diagram in Fig. 367. The resultant electromotiveforce R of phases 2 and 3 is equal and opposite to th
