AIR COMPRESSOR. The air compressor is a compound, vertical, two-cylinder compressor and is directly
connected to the main generator by a flexible coupling.
EXCITE-AUXILIARY GENERATOR. The exciter-auxiliary generator consists of two separate armatures
mounted on a common shaft, and two separate frames bolted together back-to-back. It is belt driven from the
main generator shaft.
The auxiliary generator section is regulated for constant voltage over the normal speed and load range. It
supplies power for charging the batteries and operating the electrical auxiliaries.
The exciter section furnishes excitation for the main generator, which is of the differential control type for
automatic engine loading.
