Belt/Hydraulic Drive Generator
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 determines
voltages in stator windings.
3
Stator Windings
Supply power to generator power
circuits.
4
Control Relay CR1
When 12 volts DC (battery voltage)
is applied, CR1 energizes to com-
plete the circuit allowing generator
output.
5
Capacitor C1
Engine speed and capacitor value
determine generator output.
6
Generator Power Circuit
Breaker CB1
Protects the generator windings
from overload.
7
Terminals 1T, 2T, 3T
Provides connection point for cus-
tomer supplied equipment and re-
ceptacles.
