In 3 horsepower how many amps needed?

Answer 1

3 amps on 120 volts is almost 1/2 hp. To be exact 0.48 hp, that's why I said almost 0.5 hp or 1/2 hp.

So say you are thinking of buying a 3 amp grinder or table top sander and you want to know about how many HP (Horse Power) it is, the answer is 120 volts X 3 amps = 360 X 0.00134 = 0.4824 HP which is almost a 1/2 HP

you can do the math from there if its a 6 amp motor then its almost a 1 HP motor or to be exact 0.4824 X 2 = 0.9648 also almost 1 HP. This is if you are on 120 volts. If you are on 110 or 125 volts its about the same.

Answer 2

The exact amperage required for a 3 horsepower motor will depend on the voltage at which it operates. Typically, for a single-phase motor operating at 120 volts, a 3 horsepower motor would draw around 25 amps. For a three-phase motor operating at 230 volts, it would draw around 10 amps.

Answer 3

3 horse power if it is 3phase system then it will draw apx.4.5 amps if supply voltage is 440 volts ,at frequency 50 cps. the current needed depends up on supply system parameters.

Answer 4

To answer this question a voltage is needed.
