How an Armature for Dynamo Machin
Ia Made

How an Armature for a Dynamo Machine
Is Made.
The most difficult and important part
of the structure is the armature. and
in building this the first thing is the
laminated iron core. For this pur-
pose an immense number of thin disks
OF sheet-irOn are cut out, each having a
central hole to admit the shaft, and
several other holes for the bolts which
are to hold the series of disks together,
so as 10 make of them soil drum.
These disks are then piled one upon
another around the iron shaft which
is to form the ak of the armature,
and thick iron plates are applied at
each end and bOlted together by iron
5olts going through from end to end.
The drum or cylinder thus formed is
then mounted in lathe and turned
to a smooth surface, except for
such projections as may be left
for guides in winding on the copper
wires. This is the next operation to
DE performed: The workman draws
the insu' ated copper wire down from a
drum overhead and passes it length
wise around the armature core, which
is supported by its axis in a lathe,
while another workman assists him in
pressing the wire accurately into place
Ind keeping it close to the core. This
wire is not wound on continuously, but
in number of short sections whose
ends stick out somewhat irregularly
These ends are to be attached to the
successive sections of the commutator.
The numerous radiating lines at the
nearer end Of the drum are parts of the
cOmmutatOr sections, which are at
tached at their outer ends to the sue
cessive coils of wire on the armature.
AT their nearer ends these rad ial bars
bend at right angles, so as to pass
along the surface of the shaft, being
insulated from it and from each other
by mica or other appropriate sub.
