The Cub's governor should be capable of keeping the engine rpms constant/close enough. Actually the Cub engine may not even notice the additional load on the generator head.Scrivet wrote:Not a generator expert but won't the size of the electrical load applied have an effect on the engine speed thus the generators output? Will the Cub's governor be up to the task of keeping the engine speed constant under varying electrical loads?
Example provided in opening of this topic. 3500 Watts, 6 hp engine required. These figures are the maximum.
Some figures from a numbered cub low-boy engine: 1200 rpms = 8.87 hp. 1400 rpms = 10.5 hp. Basically using 1200 rpms and 8.75 hp, the Cub engine could easily handle the 3500 watt generator head requiring 6 hp. And there are still engine rpms available to the governor.
