Instead of using pulleys, can I directly couple the generator to an engine?
Yes. In order to directly couple these generators to an extended shaft engine, you must use couplings with spider gears. These types of couplings are available from companies such as Lovejoy or Boston Gear and are available at most industrial supply companies such as WW Grainger etc. One coupling must fit the diameter of the generator shaft and one coupling must fit the diameter of the engine shaft. The spider insert fits between the two couplings to compensate for misalignment.
