en the two windings are connected inseries is the vector sum of Ei and E2 and is equal to V2# = 1.414i?and if 7 is the maximum safe current the conductors of thewinding can carry then the maximum output is 1.414 EI watts.It is therefore desirable to use the two windings A and B as ifthey belonged… … Fig. 254.—Voltage curves oftwo-phase alternator.

Since the voltage of winding B is out of phase with that ofwinding A, the machine operating as shown in Fig. 253…
