5-2 FUNCTION OF EACH COMPONENT
5-2-l GENERATOR
(1) STATOR
The stator consists of a laminated silicon steel sheet
core, a main coil and condenser coil which are
wound in the core slots.
AC and DC output are taken out from the main coil.
(DC output is taken out from the part of main coil
which is in the middle of the main coil.)
The condenser coil excites the stator field coil which
generates AC output in the main coil.
(2) CONDENSER

STATOR

The condenser is mounted on the rear housing and is connected to the condenser coil which is wound in the
stator. The condenser coil magnetizes the rotor which increases the density of magnetic flux.
(3) RECTIFICER
The rectifier is also mounted on the rear housing and it converts AC current output from the main coil to
DC current. The DC output from the diode of this rectifier is connected to the DC terminal.
(4) ROTOR
The rotor consists of a lamination silicon steel sheet
core and field coil which is wound over the core.
DC current in the filed coil magnetizes the steel
sheet core.
Two permanent magnets are provided at 90 degrees
from the poles for the primary exciting action.
A securely mounted fan is pressure-fitted on the end
of the rotor shaft to cool the individual coils, iron
s
cores, rectifier, and other integral parts.
Cooling air from the fan is drawn in from the venti-
I
lation vents in the rear housing, and is discharged
from the exhaust port in the front housing.

(5) CONTROL PANEL
The panel on the front of the housing has a recepta-
cle with a ground terminal and AC output is taken
out with a male plug.
DC output is taken out from the red (positive: +>
and black (negative, -) terminals.
Control switch, circuit breaker, voltmeter and pilot
lamp are installed on the control panel.
