Re: Gas powered engine horsepower equivalent to electrical motor horsepower?

You also need to keep in mind that engines and electric motors work very differently. If you use an electric motor at peak output power, it is not most efficient! In fact you are converting a lot of the power to heat at that point. Depending on the thermal limits of the motor, you may burn out the motor if you run at this point for a given amount of time. I don't know how long you can run an engine at peak horsepower? Maybe someone knows.

Actually I would worry more about when the motor is stalled. That's when the motor reaches 0 efficiency.

I already have a way to (theoretically) hook the original chain drive to the motor, just need to know what kind of motor I can use to make 5 hp.

Wowser none of the motors in the FIRST kit come even close to 5hp. Even the EV warrior motor which is designed to move humans is only rated at .5hp. http://www.robotcombat.com/marketplace_ev.html

We put the big black motors on a scooter and it really didnt go very fast... you also had to push off when you started to go.

Those big black motors were designed to move a six year old.
