... addition to the emf, there is only the stator resistance and leakage inductance voltage drop. Finally, as there is current (mmf) in the rotor, the emf E1 is produced concurrently by the two ... constitute the IM equations per phase reduced to the stator for the rotor circuit. Notice that in these equations there is only one frequency, the stator frequency ω1, which means that they refer ... However, in this case, the third harmonic in current does not occur. The 5th, 7th saturation harmonics occur in the current for the star connection. For the delta connection, the emf (and flux)...
