HP/.00134= Watts
Then
Watts divided by Volts = AMPS
For expample.
a .75 HP electric motor running on 220VAC uses 2.544 amps
.75 / .00134 = 559.7015 Watts
then
559.7015 / 220 = 2.544
Divide by 60.
1 tr is equivalent to how many hp?
To answer this question the voltage of the compressor is needed.
The conversion factor is 1.34. So: .78 kW x 1.34 = 1.0452 hp
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.
To answer this question a voltage is needed. 1 HP = 746 Watts. Amps = Watts/Volts.
To calculate the HP of a motor, you can use the formula: HP = (Watts x Efficiency) / 746 Where Efficiency is a typical value between 0.7 and 0.9. For a 3 amp motor, you will need to know the voltage to calculate the wattage and then convert it to HP using the formula above.
Divide by 60.

547c.f. Converted to hp
To convert Watts (W) to a horsepower rating (HP) simply multiply the Watts by 0.00134 W x 0.00134 = HP
you dont
You don't. Hp and bar measure completely different things.
