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 long will a 10 watt pump run a 12v 70 amp battery?
To answer this question the amperage draw of the motor must be given. This amperage is then divided into the amp hour capacity of the battery to find the endurance time of the motor.
Why do you need a 125 amp breaker for a 83 amp furnace?
If you put a 85 amp breaker in there it will overheat from the starting and stopping of the motor. The extra size of the breaker insures that the furnace will run without interruption and without overheating the breaker. And electric motor can draw three times the amperage rated on start up momentarily. This is why there is need of extra amperage ratings.
How many amps should a 0.5 horsepower motor draw?
Depends on the voltage. If you are running off 120 VAC, a 0.5 horsepower motor would draw 3.1 A.
What is the cable size for motor 15kw 440 volts connection?
The current draw is about 27 amps. A motor feeder has to be 125% of the motors full load amperage. 27 x 125% = 33 amps. A #8 copper conductor with an insulation factor of 90 degrees C is rated at 40 amps.
Does ballast use amps?
Yes a ballast uses amperage. That is the number beside the letter A on the ballasts nameplate. Depending on the size of the lamp or lamps will govern the size of the amperage that the ballast will draw.
Can you run a motor of greater amperage draw with a motor of less amperage draw?
It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.
If my AC technician says my unit is rated at 28.9 amps and drawing 24.8 and should draw about half of rated capacity and that compressor needs to be replaced Is this correct?
There are several amperage ratings on AC compressors/motors. Locked Motor Amperage (LRA) is the amperage that the motor is fused for. The load of the motor is expressed in amperage or wattage, which is probably the case here. Low amperage readings on an AC unit being charged by amperage load would indicate low freon. High amperage readings indicate overcharge when charging by the amperage load. AC units are not accurately charged by amperage readings and the efficiency of motors is not expressed in amperage readings.
What makes a marine battery's terminals hot?
Amperage draw, excessive amperage draw, and or dirty & loose connections. This should be checked out if the temperature is elevated when not cranking your engine.
How long will a 10 watt pump run a 12v 70 amp battery?
To answer this question the amperage draw of the motor must be given. This amperage is then divided into the amp hour capacity of the battery to find the endurance time of the motor.
Does a 5 hp electric motor draw less amperage if it is not doing 5 hp of work?
All motors draw less current when their load reduces.
A cranking motor has an unusually high amperage draw accompanied byslow cranking speed?
most likely a failing starter
How many amps does a 2 hp 210 volt single phase motor draw?
Then you are trying to get more HP out of the motor that it can supply. Back off on the load that the motor is driving or put a bigger motor onto the load.
Why does the blower fan resistor keep burning out on 99 villager?
It is quite possible the blower motor is drawing too much amperage. This is caused by a motor that is wearing out and starting to drag slightly drawing more amps to keep the motor turning. It can also have dirty wire connections at motor causing high amperage draw...
Is it correct to use the Fast fuses for one three phases Induction motor start up?
No, if anything motors need time delay fuses in the start up phase of their rotation. The motor will draw up to 300% of their full load amperage. Time delay fuses get the start up current past this phase of start up.
Why does a cranking motor have an unusually high amperage draw accompanied by a slow cranking speed?
The armature bushings inside the starter motor are probably shot. Time to replace the starter.
Can using larger wire sizes reduce amp draw?
Larger wires will not reduce the amperage draw of a device. Limiting amperage draw is accomplished by fuses wich blow when the amperage drawn across them exceeds their specifications.
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.
