The rotor consists of a laminated silicon steel sheet
core and field coil which is wound over the core.
DC current in the field coil magnetizes the steel
sheet core. Two permanent magnets are provided for
the
primary exciting action.
A
cooling fan
is
pressure-fitted on the end of the
rotor shaft to cool the
coils,
cores, rectifier, and other
generator parts.
(See

and
resister are mounted inside of
the .insulator. (See Fig.

Cooling air is sucked by the rotor fan through the
slits of the rear cover and is expelled through the
outlets
of
the front cover.
