LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - Continued
The alternator (Figure 1, Sheet 1, Item 5) is located on the right side of the engine. The alternator maintains the
batteries in a state of full charge. The alternator also provides 24 Vdc voltage for TQG control circuits and to the
NATO slave receptacle. After starting the engine the voltage output is 28 2 Vdc.
The radiator (Figure 1, Sheet 1, Item 6) located at the front of the TQG eliminates engine heat via circulated
coolant and air. The radiator and engine fan are the primary heat exchanger for cooling engine coolant and
turbocharged engine intake air.
The water pump (Figure 1, Sheet 1, Item 7) located on the right side of the engine circulates coolant through the
engine block and radiator to cool the engine.
The engine starter motor (Figure 1, Sheet 2, Item 8) is located on the right rear side of the engine. The electric
starter engages the flywheel mechanically to start the diesel engine.
The load board (Figure 1, Sheet 2, Item 9) connects load cables to the TQG with heavy duty connector lugs and
The reconnection board (Figure 1, Sheet 2, Item 10) is used to change the TQG generator output voltage for
different load applications. The TQG can be configured for 120/208 Vac or 240/416 Vac operation for 50 Hz or 60
MAIN LOAD CONTACTOR
The main load contactor K1 (Figure 1, Sheet 2, Item 11) connects/disconnects generator load output to the load
The generator (Figure 1, Sheet 2, Item 12) used in the 100 kW TQG is designed to meet military applications for
the TQG. The generator is a brushless, single bearing, rotating rectifier generator. It is close-coupled to the
engine via flexible drive disks. Each generator consists of five major components: main stator (armature), main
rotor (field), exciter stator (field), exciter rotor (armature), and rotating rectifier assembly.
