ive forces induced in the two imaginary phase windingswhich we are specially considering will be in phase with E^ and E^ since theyare co-axial with the actual stator winding, and, moreover, they wiU beproportional to their respective magnetising ampere-turns OP^ and OP^.Hence, the resultant OF… … Fig- 431 are exactly equal, and therefore OP^ and OP^, are also equal, and are addedalgebraically together to give the maximum value of the actual ampere-turnswith open rotor. Obviously then OF represents this latter magnitude whichwe have called Zq. We now make t Pfi^ = -.OP^ and P^P = ^-.OP, and…
