Abstract: Some embodiments relate to a method of sensing generator speed. The method includes detecting an AC waveform produced by a generator and determining a threshold voltage from the AC waveform produced by the generator. The method further includes determining generator speed by comparing the threshold voltage with the AC waveform. The generator speed may be determined by a time period between cycles of an output of the generator. Other example embodiments relate to a method that includes detecting an AC waveform produced by an alternative stator winding within the generator and measuring the period of the AC waveform to inversely determine generator speed.

Abstract: Some embodiments relate to an engine driven generator that includes a first electrical fan and a second electrical fan. The engine driven generator further includes a power source and a circuit connecting the power source to the first electrical fan and the second electrical fan. The circuit is configured to selectively connect the first electrical fan and the second electrical fan in series or in parallel. The circuit may operate the first electrical fan and the second electrical fan at full speed when the first electrical fan and the second electrical fan are electrically connected in parallel. The circuit may operate the first electrical fan and the second electrical fan at less than full speed when the first electrical fan and the second electrical fan are electrically connected in series.
