Question about Coleman Powermate Premium Plus 6250W Portable Generator
Changed capacitor.. Old was checked OK 60.9 hz 39.4 ohms on rotor If I lower RPM how does this effect htz Local motor shop was concerned about lowering RPM on engin to 3600 as it would lower htz to 50.5 or something in that area. I think the problem started when it was backfed from power co line.... up until then. it worked fine. Is it possible that engin speed was affected when this happened.... Maybe it was lightening that caused it.... We had lightening that night and we had other problems
The thing more important than frequency (Hz) is the voltage with no/light load. It should not be over 130 under any circumstances. You will never maintain both frequency voltage with these small generators. With a light load, voltage may be 120-125, and with a heavy load, maybe 110 to 115. The frequency may vary between 58-59 and 60-63, but there is nothing you can do about that. Just make sure the voltage does not go too high. If you always run a fairly light load, then back it off so it's no more than about 125. Don't worry about RPM; worry about voltage. Unless your generator is a 50 Hz generator, it will produce exactly 60 Hz at exactly 3600 RPM. Your shop person's RPM meter is faulty.
And by the way, you should not have had it hooked up so it could possibly have been back-fed by the power company in the first place. You could easily have killed someone working on power lines. If you don't know how to hook it up safely, then you do not need power that badly. It's not worth someone's life.
