In a fit of insomnia last night I realised that the formula I gave
for sizing the hp requirement was a load of old bollocks. ie
incorrect. It should read : 11000/750/.8 = about 18.5 hp required.
My apologies.

I suggest a vw rabbit diesel, which puts out 52 hp at about 3600 rpm, but at
1500rpm, might be about right. I am not absolutely sure about hp
requirements for gennies, but I have a 4,000 watt gas gen. that has an 8hp
engine. so, 750watts x 8 hp x.65 = 4200 watts. Don't forget that you need
enough

Hi Justin
You will find that in 99% of cases, fixed generating powerplants
above a certain size are almost exclusively diesel powered. That
size I'm guessing now, probably around 15KVA. Diesel motors make
good usable power at 1500rpm. I suggest that you are barking up the
wrong tree so to spe
The problem is the higher the rpm the more noisy and the faster they wear out.
Also a V belt or transmission has losses associated with it (in the 10%
reqion )

- You did not mention how you intend to connect the motor to the
generator but you might consider a vbelt and pulley setup where you
could change the pulleys to get into the power range of whatever
enging you decide upon and still maintain the 1500 rpm needed. Just a
thought. gaw-
