Generator
The CS130D generator is non-repairable. They are electrically similar
to earlier models. The generator features the following major components:
• | The rotor with slip rings and brushes |
The pulley and the fan cool the slip ring and the frame.
The AD stands for Air-cooled Dual internal fan; the 2 is an electrical
design designator; the 30 denotes the outside diameter of the stator laminations
in millimeters, over 100 millimeters. The generator (K60) is rated at 100
amperes, the (K68) is rated at 105 amperes.
The generator features permanently lubricated bearings. Service should
only include the tightening of mounting components. Otherwise, the generator
is replaced as a complete unit.
Regulator
The voltage regulator controls the field current of the rotor in order
to limit system voltage. The regulator switches the current on and off at
a rate of 400 cycles per second in order to perform the following functions:
• | Obtain the correct average current needed for proper system voltage
control |
At high speeds, the on-time may be 10 percent with the off-time
at 90 percent. At low speeds, the on-time may be 90 percent
and the off-time 10 percent.
