Again, the dynamo is a machine driven by power, generally steam or water power, and converting the mechanical energy expended in driving it, into electrical energy of the current form.

To summarize, the dynamo-electric generator or the dynamo-electric machine, proper, consists of five principal parts, viz:

1. The armature or revolving portion.

2. The field magnets, which produce the magnetic field in which the armature turns.

3. The pole-pieces.

4. The commutator or collector.

5. The collecting-brushes that rest on the commutator cylinder and take off the current of electricity generated by the machine.

Fig. 218 shows a dynamo of the early Edison type—the names of the principal parts are given in the note below, as well as those of the other parts of the machine.
