I come up with 426 hp...

Most GC motors are in the neighborhood of 85% cold and degrade as the temperature of the motor increases. The decrease in efficiency is due to decreased resistance of the field coil wiring and decreased magnetic properties of the magnets. The speed of the motor is also critical concerning brush contact in feet per minute.

It's a pretty complicated process but if you'd like more info that will leave everyone but and electromechanical engineer seeing sideways. This is way more than I wanted to say except there's no real easy answer.

amps (A) =1200 & volts (V)=265 then A X V = 318,000 watts (W) 318,000 x .00134 = 426.12 hp...

----------------------------------------------------

Amps are a factor in calculating power, and so can be used to determine horsepower, but only when other factors are present.

Given other factors, you can find the horsepower. The easiest way is to determine watts by multiplying amps X volts. Next multiply watts by .00134 and you have horsepower.

If: amps (A)= 20 and volts (V)=120 then

A X V =2400 watts (W)

2400 watts X .00134 = 3.216 horsepower
