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
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
What size capacitor is needed to start a 1 hp 14 amp 110V motor?
A single phase motor does not actually require a capacitor. This device is only needed when a split phase motor is utilised. A split phase motor needs a device to regulate the power factor associated with the split phase.
What current will a 100w electric fan motor draw when you plug it into a 240v wall socket?
0.4166666
How many amps does a 0.75 hp 550 volt single phase motor draw?
At peak power it should draw 1.36 amp at power factor 1 or more realistically 1.7 amp at power factor 1.7.
Would 10mm sq cable suit an 18kw 3 phase 415 volt motor 25mt length?
The motor would draw about 24 kVA which is 35 amps. For this you would need 10 mm2 cable.
Would 10mm sq cable suit an 18kw 3 phase 415 volt motor over 25mt length?
The motor would draw about 24 kVA which is 35 amps. For this you would need 10 mm2 cable.
How does the 3-phase induction motor acts like 2-phase induction motor if a phase is disconnected from supply?
yes the motor will run but will draw more current and the torque will be not constant means not smooth due to unbalanced current
What would be the horse power required in a 3-phase motor to replace a .5 horsepower single phase motor.?
You still need the same horsepower. The advantage of the three-phase motor is that it will draw lower current.
What is the phase current of a three phase 2.2kw 415v motor connected in star?
The line current would be the same if the motor were connected in delta. The current can be based on the rule of thumb which says 7 amps must be allowed for a 1-HP single-phase motor on 240 v. A 2.2 kW motor is three times as powerful, and on a three-phase supply of the same voltage (240/415) it would draw 7 amps.
Should all 3 phases of a motor draw the same amperage?
Yes. they should. The windings in a three phase motor are identical, and provided they are fed with a supply that has the phases at the correct voltage, and at the correct 'phase angles' to each-other, they should each draw the same current from each supply line. (Motor windings are a 'balanced' load - they will all draw the same current from the lines if the supply is okay and the windings are connected correctly, and have no shorts or opens in them.) Some three phase motors can be connected to run off of a single phase line, using capacitors to give phase shifts to simulate 3 phase. This is an 'unbalanced' 3 phase supply as far as the motor is concerned, and while it WILL work, the motor will develop less staring torque, less full load power, and more noise - and it WILL draw different currents in each 'phase' while running.
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
How much current will a 15 hp single phase 220 volt fan motor draw?
The wiring should allow for 115 amps.
Will a 10 hp 220 volt motor draw large amounts of electricity?
A single phase 10 HP motor will draw aproximately 50 amps. A three phase 10 HP motor will draw aproximately 28 amps.
Why motor burn at single phasing?
A 3-phase motor will not run on single-phase power or if one of the three phases is disconnected. If the motor is not running, there is no back-EMF generated in the coils, and they draw excessive current, thus overheating.
How many watts is 1 hp at 480volts?
A 1-HP motor is reckoned to draw 7 amps at 240 v single-phase. The same power of motor would draw 3.5 amps at 480 v single-phase, but a 480 v supply could most likely be a three-phase suppy, and the current in that case would be reckoned as 2 amps.
Is amp draw on a 220V motor per leg or combined?
Amp draw is always combined. 220V is uncertain if it is three phase or not, because there are both one phase and three phase applications of the 220V motor. In any case, the answer is always "combined".
