The rotor would be placed inside the stator. Instead of a permanent magnet, this machine (as do the overwhelming majority of synchronous machines) uses an electromagnet to create the field. A DC voltage is applied to the coils on the rotor, creating north and south poles. This particular rotor is called a salient-pole rotor because the rotor is not symmetric. In particular, the air gapbetween the pole f
