How many amps does a half horse power motor draw at 220 Volts?

to calculate:

1hp=745W

3hp=745*3=2.2Kw

assuming a 3 phase motor

power is V*I*pf*the square root of 3

I would gues a PF of 0.8 if its a resonable motor which gives about 7.2 amps per phase.

if the PF is bad say .65 it could pull up to 9 amps

in short, too little information to give you the actual answer.
