Abstract
In an engine-generator set, the generator has a first shaft driving a generator armature and also has a second shaft in spaced relationship to the first shaft. The second shaft is coupled to the engine and there is a gear on each of the shafts which provides a 'step-down' gear reduction for powering the generator at, e.g., 1800 rpm, where the engine speed is greater than 1800 rpm. Preferably, the engine is coupled to the generator armature shaft through a torsional coupling for isolating engine vibration from the generator.
