Consider the balanced three-phase alternating currents, shown in Figure P12.3.4 (a), to be flowing in phases a, b, and c, respectively, of the two pole stator structure shown in Figure P12.3.4
(a), sketch the individual phase flux contributions and their resultants in vectorial form.
(b) with balanced three-phase windings. For instants t = t1, t3, and t5 of Figure P12.3.4
