To answer your question properly, you need to know the input power to these machines, whereas you are specifying their output powers. In other words, you really need to know their efficiencies in order to determine their input powers.

Once you have figured out their input powers, then you need to divide the power by the supply voltage in the case of the single-phase motor, and the power divided by 1.732 times the supply voltage in the case of the three-phase motor.


Incidentally, your motors' specs should either be 230/400 V or 240/415 V, NOT 230/415 V.

Can 208 V single phase power a 220 V single phase motor?

This is a 15% overvoltage to the motor, which is generally outside the specifications for a motor spec'd at 208v (typically up to 10% overvoltage is tolerable). Your 240 volt source may be as much as 105% of 240 / 252 volts at times. A buck/boost transformer should be used, unless the motor is designed to be used at 240 volts.


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.


How much a 3 ampere motor 220 v single phase is equal in kw?

As watts are made of volts times amps, the answer would be 0.660kw.


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.


Will a 500volt 50hz squirrel cage motor run on 380volts 50hz?

No, the voltage of 500 volts is too high to operate a 380 volt motor.

It is probably a three phase 50 Hz motor.


How much current will a 5 HP single phase 220 volt motor draw?

P=VI P=power V=voltage I=current therefore current drawn is 5000/400=50/4=12.5 amperes


What is max single phase hp as per nec?

The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.

Will it hurt 230 volt single phase motor plugged into 277 V single phase?

Yes, plugging a 230V single phase motor into a 277V single phase power supply can potentially damage the motor due to the higher voltage. It is recommended to match the voltage ratings of the motor and power supply to prevent any issues.


Can an air conditioner unit running on 250 volts be run directly by 120 volts?

No, the unit has to operate on the voltage specified. The internal controls are all designed to operate on a 240 volt input. The motor in the air conditioner will not operate at the lower voltage and without this compressor motor operating the unit will not get cold.

What is the maximum volts that can be used on a 208 230 volt motor?

You should not go above 240 volts for that type of motor.


How many amps will a 3 hp motor pull on 230 volts?

It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.

In 3 horsepower how many amps needed?

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.
