Unformatted text preview: c) Draw the MMF diagram at t =0; when all three phases are excited by balanced 3-phase currents. Compare the MMF diagram you obtain with what you found in (b). Comment on the magnitude and phase of the two waveforms. d) Draw the MMF diagram if the resultant magnetic field is shifted by 60 electrical degrees. i. determine phase currents for this condition j. Determine the mechanical angle by which the resultant magnetic field axis moved as compared to (c). k. Comment on the MMF shapes obtained for (c) and (d) Please prepare eligible drawings....
