SECTION 6 − 7.5 kW MODELS THEORY OF OPERATION
1
Engine
Supplies force to turn revolving
field (rotor).
2
Revolving Field (Rotor)
Turns at 3000 rpm (50 Hz) or 3600
rpm (60 Hz). The speed and excita-
tion current of the field coils deter-
mine voltages in stator windings.
3
Stator Windings
Supply power to exciter and gener-
ator power circuits.
4
Power Board PC1
Works with PC2 to adjust output by
changing revolving field current af-
ter comparing feedback from PC2
to generator open-circuit voltage.
Uses current feedback signal for
current limiting circuit to prevent ro-
tor failure from overheating.
5
Control Board PC2
Works with PC1 to regulate revolv-
ing field current. The PWM (pulse
width modulation) signal originates
on PC2 and is sent to PC1.
6
Generator Power Circuit
Breaker CB1
Protects the generator windings
from overload.
7
Terminal Block TE1
Provides connection point for cus-
tomer supplied equipment and re-
ceptacles.
