If the assumption be made that the coefficient of self-induction of thearmature of a machine has a constant value for all conditions of load andexcitation, the vector diagram is extremely simple.

Thedirection of the current vector in Fig. 307 is vertically upwards. The self-induction induces an e.m.f. lagging 90° behind the current, which…
