How many amps does a 60 hp 460 volt motor draw?

750 watts per horse power20 x 750 = 15,000 watts / 220V = 68A68 amps at 220 volts


Convert 250 kilowatts to amps with 460 volts 3 phase?

You have to know the power loading and phase angle (or power factor) between each pairh of the phases, otherwise you could be making serious errors.


Will a 60kw generator that puts out 477v 3-phase power run a machine that requires 230460v 3-phase?

Crank the generator excitation up to 480 or down to 460. For calculations I used 480 volts. A 60kW generator at 480 volts will put out, kW x 1000/1.73 x E x (pf(.9)) = 80 amps. It looks like the machine that is to be run off the generator is a dual voltage machine. Not knowing the HP of the machine wire it to the 460 volt connection. The inrush current might be a problem if the HP is high.


How many amps does a one horse power motor draw?

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.


Are all large motors three-phase?

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.
