Question

In the 2-pole machine shown below, ia = Im cos(@t – 60), i, = Im cos(wt – 180°), and ic = Im cos(wt + 60°). Assume current Im creates a

flux density with magnitude of Bm.At wt = 0, plot the flux density vector created by each phase, the resultant flux density||space vector (created by all three phases) and the resultant flux lines. Specify the magnitude(in terms of B.) of each vector.
