How much current will a 15 hp single phase 220 volt fan motor draw?
The wiring should allow for 115 amps.
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 3 phase 22kw motor use?
22 kw motor how much takes ampares with load
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.
Can you replace a three phase motor 3 Hp RPM 1420 with a single phase motor for a planer?
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
How much amps of 3000watts on 220volt ac single phase?
3000/220 =13.63amps
How much current will a 15 hp single phase 220 volt fan motor draw?
The wiring should allow for 115 amps.
How much breaker load Amps required for 31 kw?
Impossible to say without more details. It depends entirely on the voltage of the supply and whether it's single-phase or three-phase.
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 different is the horsepower used by an air conditioner unit if it runs on either single phase or three phase ac?
There is no difference in horsepower. The manufacturer builds the air conditioner. Engineers calculate and tell the manufacturer how much power is going to be required to make it operate. Smaller units will probably use lower voltage with lower horsepower to operate efficiently. The bigger the unit will take higher horsepower to operate. There comes a point when single phase, low voltage use will not work due to the unavailability of high horsepower, low voltage motors. At this point three phase systems are used with higher voltages to operate the motors. Examples of a 10 HP motor at different voltages. Single phase - 115 volts 100 amps, 230 volts 50 amps. Three phase same HP - 200 volts 32.2, 230 volts 28, 460 volts 14 and 575 volts 11 amps. As you can see if the air conditioner needs a 10 HP motor at single phase 115 volts, a feeder supply of 100 amps would be needed. This compared to the same air conditioner using a three phase 575 volt system which draws 11 amps.
Can you convert a 3 phase convection oven to single phase?
I dont know if you can actually convert the oven's wiring from 3-phase to single phase. You can, however, convert the single phase circuit that will feed the oven to a 3-phase system. To this you will need a phase converter. Now, where to purchase such an item, and how much they cost? i have no idea.
When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
What are the Advantage of three phase motors over single phase?
A 3 phase system needs only to use 3 or 4 conductors, as against 6 conductors if it were 3, single phase conductors The amount of copper used in a 3 phase is much less than what would be needed in a single phase system carrying the same current, this reduction in copper allows for weight reduction and cost savings. The power losses in a 3 phase system are much less than in a single phase system.
Is converting ac to watts and dc to watts the same watts equals volts times amps?
Yes, watts is still volts times amps, for both ac and dc circuits. The complexity lies in the phase angle between voltage and current. If the circuit is purely resistive, the phase angle will be zero. If the circuit is capacitive or inductive, the the phase angle will vary, depending on frequency and on how much capacitive or inductive reactance there is. The difference comes into play when you consider true versus apparent power.
How many amps does a 3 phase 22kw motor use?
22 kw motor how much takes ampares with load

Which is bigger between .5 amp and .400mA?
.5 amps equals 500 ma, which is much larger than .400 ma.If you meant between .5 amps and 400 ma, then again, .5 amps equals 500 ma, which is larger than 400 ma by a factor of 100 ma.
