+ | > Typically, a United States portable generator runs at 3600 RPM, with 2 poles, for a design frequency of 60Hz.((https:// | ||

+ | Things that affect RPM (load changes, etc) will affect the output and can cause "dirty power" (varying frequency). | ||
+ | |||
+ | > You get fluctuation of frequency and voltage as the load changes because the engine cannot respond immediately to the actual load change. There are regulators controlling the engine throttle that attempt to keep the engine at a fixed (design) speed, but it takes time for the engine to respond to new commands as it has to deal with varying fuel/air mixtures and combustion which aren't instantaneous.((https:// | ||
