Dynamograph.
A printing telegraph in which the message is printed at both
transmitting and receiving ends.
Dynamo, Inductor.
A generator in which the armature or current-generating windings are all
comprised upon the poles of the field magnets. Masses of iron, which
should be laminated and are the inductors, are carried past the field
magnet poles concentrating in their passage the lines of force, thus
inducing currents in the coils. In one construction shown in the cut the
field magnets a, a .. are U shaped and are arranged in a circle, their
poles pointing inwards. A single exciting coil c, c ... is wound around
the circle in the bend of the V-shaped segments. The poles carry the
armature coils e, e ... The laminated inductors i, i ... are mounted on
a shaft S, by spiders h, to be rotated inside the circle of magnets,
thus generating an alternating current.
Synonym--Inductor Generator.

Dynamo, Interior Pole.
A dynamo with a ring armature, with field magnet pole pieces which
extend within the ring.
