Small synchronous machines – use slip rings and brushes. Larger machines – brushless exciters are used to supply the dc field current. A brushless exciter is a small ac generator with its field circuit mounted on the stator and its armature circuit mounted on the rotor shaft. The 3-phase output of the exciter generator is rectified to direct

The magnetic poles can be either salient (sticking out of rotor surface) or non-salient construction. Non-salient-pole rotor: usually two- and four-pole rotors. Salient-pole rotor: four and more poles.

As shown in Figure 1, the rotor can be of either the salient-pole type or the cylindrical (non-salient-pole) type. The machine used for this experiment is somewhat salient, but the impact of the salient is negligible.
