as slip at starting (nr= 0.0) is 1.0,which is the same at standstill (or stalling condition). The magnitude of the induced voltage per phase in the stator winding is nearly same as input voltage per phase fed to the stator, if the voltage drop in the stator impedance, being small, is neglected, i.e. VsÃ¢â€°Ë†Vs, the ratio of the induced emfs per phase in the stator and rotor winding can be taken as the ratio of the effective turns in two windings, i.e. Es/Er= ts' =kwsTs and Tr' = kwrTr. The winding factor for the stator winding is kws = kdsÃ¢â‚¬Â¢kps. Same formula is used for the above factor in the rotor winding, assuming it to be wound rotor one.
