Horsepower is a rating of power, and power is equivalent to voltage times current.
AnswerThe horsepower is the Imperial unit for power, whereas the volt is the SI unit for potential difference. These are two different quantities, so your question makes no sense. It's like asking how many miles per hour there are in 10 metres!
The rule of thumb is 746 watt per horsepower.
The formula for single phase HP = I x E x %Eff x pf/746
The formula for three phase HP = I x E x 1.73 x %Eff x pf/746
The formula you are looking for is I = HP x 746/1.73 x Volts x %Eff. x pf.
There are 746 watts in 1 HP. Watts = amps x volts. It depends on the voltage rating of the motor. Amps = 746/volts = ? need voltage.
It depends on how many Amps (current) are applied to the voltage. Watt = Volts x Amps. e.g. 12 volts @ 5 amps = 60 watts
Yes, most large motors are three phase. Usually single phase motors only go up to 10 HP. Larger than this and the wire size and contactors used to control the motors becomes extreme. For example a single phase 10 HP motor on 115 volts draws 100 amps. The same single phase motor on 230 volts draws 50 amps. The same 10 HP motor on three phase system draws the following amperage; 230 volts is a 28 amp draw, 460 volts is a 14 amp draw and 575 volts is a 11 amp draw. As you can see the higher the voltage becomes, the smaller the wire feeder size is needed and much smaller size contactor can be used to control 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.
The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.
To answer this question a voltage is needed. 1 HP = 746 Watts. Amps = Watts/Volts.
How to convert horsepower to amps? You'd have to make an assumption about volts. If it's running at 220 volts, that would make it 34 Amps. There are 746 watts in a horsepower and Amps = Watts/Volts.
what is the full load amps for 2.4 hp motor at 460 volts ?
For a single phase 3 HP motor at 208 volts the amperage is 18.7 amps. For a three phase 3 HP motor at 208 volts the amperage is 10.5 amps. This figure is derived at by taking the full load amps at 230 volts and adding 10%. As the voltage goes down the amperage goes up. For 200 volt motors 15% is added to the FLA of a 230 volt motor.
4500 watts is zero volts. To obtain a voltage from watts it has to be divided by an amperage.
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.
The formula you are looking for is I = HP x 746/1.73 x Volts x %Eff. x pf.
1 HP = 746 watts. Watts = amps x volts. 7 x 110 = 770 watts. 770/746 = 1.032 HP
