FIGURE 5.4 (a) A simple four-pole stator winding. (b) The resulting stator magnetic poles. Notice that
there are moving poles of alternating polarity every 90° around the stator surface. (c) A winding diagram of
the stator as seen from its inner surface, showing how the stator currents produce north and south magnetic
poles.
