uxes O^,and Oj, produce a perfect rotating field and since the rotor conductors donot cut the field, no e.m.f. is induced. Hence Ey and E^^ are in opposition. It is noteworthy that the difference Ey — E„, which represents the totalback E.M.F. in the exciting circuit of the rotor, is wattless.… … EryI \ :e^A 0 *., Eu Fig- 451 The stator current I (Fig. 450) induces in the rotor the e.m.f. OD = C.X.I (a), and in the stator itself due to its leakage flux, the e.m.f. OE =Ti.Z.7 (6). Both of these lag 90° behind the stator current.The rotor current I^ induces in the rotor itself an e.m.f.
