The Drum Armature  consists of conductors wound lengthwise upon a cylinder of iron. The ends of each coil are connected to adjacent commutator bars. This form is used for lower E. M. F. than the ring armature. If a large current is to be taken from the machine, the conductors are made of copper bars or rods.
