solution

Unbalanced MMF The conductor turns density of a two-phase machine is given by nas = 100 cos 20 sm Nbs =-100 sin 2sm The a- and b-phase currents are given by Las = 5 cos(400t) ibs = 4 sin(400t) Express the total stator MMF as the sum of a forward and reverse traveling wave. Now, at tk/10 and Osm=0.1 compute the following: la) The value of the total stator MMF at the specified time and position 1b) The value of the forward traveling wave component of the MMF at the specified time and position. lc) The value of the reverse traveling wave component of the MMF at the specified time and position.
