Free Electricity?

Hay guy's, what do you think,
I saw a generator that produces 20amps at 110volts. It takes a 5hp. Gas engine running at 3600rpm to produce this amperage.
Now I see for sale a 5hp. Electric motor (no capacitors) that runs at 3600rpm. Using 18.5amps. to start, and 15amps. to run.
Shouldn't the generator run the motor and in turn run it self (when kick started) with 5amps. left to spare?

I think your on to something... You can make a perpetual motion machine!

Please let me know where to get a 5HP electric motor that plugs into 110volts and only draws 15Amps. I need a bunch of them.

Is it 20A peek (surge), generator?
Also 15A @ 110Vac no load?

You'got a magic motor, 1 hp = 746 watt, 5 hp = 3730 watts,
3730 watt/ 110 vac = 34 amps. This would be with a 100% efficiency motor ...

i haven't done the math myself by tmp's post suggest to me that the motor you are looking at is a 220V motor. As well, keep in mind that the HP of the generator prime mover will not be equal to the HP of the final load due to losses in the engine, losses in the generator, and losses in the motor.

Please, would you provide more info such as nameplate data of the generator and the motor.
