Electric Motor

How do I size an electric motor?

I'd like to play around with replacing a 2.5hp gas engine with an AC electric motor, but with this economy, I can't afford the trial & error approach right now. From my work with other electric motors, I don't see a need for a 1:1 conversion. Is there a formula that will help?

If you need a 2.5HP gas engine, surely you'll need an electric motor rated at 2.5HP too. For the best efficiency and lowest running cost use a motor that can run at 230V - it will use cost half as much to run as a 115V motor.
