These end caps may close the cylinder entirely or not, butusually one end is closed completely, while the other is left open, as shown, tor easy accessto the brushes and commutator. The armature, shown in section in Fig. 35, is polar, andconsists of three helices, wound upon as many radial cores, set at equal distances upon a. Pig. 33.—Spiague armature.
