Using a motorbike engine to rotate a generator

[regencydon]

Hi,
I am thinking to use a 100c 8hp motorbike engine to rotate a 2KW generator which must be turned at 1500rpm. I thought of setting the bike engine to 2200rpm on no load so that when I put the generator on full load, the rpm hopefully will not go under 1500rpm. So what I want to know is, if the generator produces 240v at 1500 rpm and if i run the engine at 2200rpm, will the generator produce more than 240v. If so, if I fit a voltage regulator to the output of the generator, will it reduce the volt to 240v constant. Please help me with this guys

You mean AC generators, right?

How voltage changes with RPM depends on what kind of generator, induction, synchronous, variable frequency?

Yes you need a voltage regulator, and a speed governor if the electric load is variable, and a AC frequency reference if using an induction generator.

By the way, a gas motor paired with a generator is called a genset. Such as this one:
