Re: \Generator speed vs frequency

Wow, Herbert, that sounds very good, indeed. Yes, there are many options to the old legacy designs running at fixed (and inefficient) rpm that give quiet(er) operation, better fuel economy, cleaner emissions and weight savings.

we have an Fischer Panda 4000i with a 1 cylinder kubota engine, 4kw.  Initial it had fixed RPM ~2900 but two years ago I upgraded it with a variable speed option (step motor that pushes the throttle depending on the load), now it turns between 2400 and 2900, depending on the load.  normally it runs with low speed because normal load is 1 to 2 kw, so it runs with ~2500. It runs more silent now and only uses ~0,5l diesel per hour compared to ~0.8l we used before.
