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.
A half horsepower motor draws between 2.3 & 3.2 amps at 220 Volts depending on the efficiency.
1 HP is 746 watts in principle. The power is in watts, and the power is the volts times the amps. For an AC motor the power is the volts times the amps times the power factor times a factor that depends on the power-conversion efficiency of the motor.
depends what the source voltage isone horsepower equals to 746watts (assuming 100% efficiency)746 watts divided by voltage source equals current (amps)AnswerIn countries, such as the USA, where the horsepower is still used as a means of measuring power, it is always used to measure the output power of a motor.So, in order to determine the current drawn by the motor, you will first need to find out its input power. The input power is the output power divided by the machine's efficiency. Once you know its input power, then you can find its current by dividing the input power by the supply voltage. In practise, you will need to use a wattmeter to determine its input power.
volts times amps equal watts, or 550 lbs per sec equals 1 horse power.
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 9.2 amps equals 2208 watts. One horse power is 746 watts.
Need to know the voltage of the motor.
1 HP is 746 watts in principle. The power is in watts, and the power is the volts times the amps. For an AC motor the power is the volts times the amps times the power factor times a factor that depends on the power-conversion efficiency of the motor.
Depends on the ratings(volts, amps, etc.) Definitely not an AC motor.

Horses are strong, amps have no strength at all unless they have volts riding along with them. The power of an amp is the current in amps times the voltage in volts. So 1 amp at 746 volts equals 746 watts, which is also one horse-power. The same wcould be achieved by 10 amps at 74.6 volts.
Volts isn't power. Volts times amps is power, also known as watts. Thus 480 volts at 2 amps consumes 960 watts, which is the same power usage of 240 volts at 4 amps or 120 volts at 8 Amps.
what is the full load amps for 2.4 hp motor at 460 volts ?
Watts = Volts times Amps. Therefore, if the voltage was 220 volts, the motor would draw 500 amps. If the voltage was 4,000 volts, the motor would draw 27.5 amps. The voltages for large powerful motors tend to be relatively high, for example in the 380 Volts to 11,500 Volts range.
6 amps.
Volts * Amps = Watts 120 Volts * 12.5 Amps = 1500 Watts Doesn't sound like a good idea.
Amps are not directly convertible to horse power, which is a measure of power. Power is current times voltage. Therefore on a 240 v supply, 40 amps equals 9600 watts. One horse power is 746 watts.
Volts cause current to flow through the load. The current is measured in amps, and the volts multiplied by the amps gives the power in watts.
volts times amps equal watts, or 550 lbs per sec equals 1 horse power.
