Alternators supply all of the output current through the commutators and brush assemblies.
Induced windings of the alternators are rotating (rotor), and the dynamos have a rotary inductor coil.
The alternators generate much less power than DC generators.
Induced (output) windings of the alternators are fixed (stator), and the dynamos have a fixed inductor (field) coil.
