How do you calculate 3ph AC motor power?
317.025280 KILOWATTS = 317,025.28 WATTS
we can calculate power consumption of motor by multiplying voltage and current which motor is take.AnswerYou need to know its rated power (i.e. its output power) and its full-load efficiency, from which you can calculate its input power.
how to connect power capacitor with 3 phase motor
You will need to determine the power per phase, and add them up to give the total power of the three-phase load. To do this, you will need to multiply the phase-voltage by the phase current by the power factor -for each phase.
Power in a 3 phase circuit is given by W=√3*V*I*cosφ therefore transposing the formula gives: I=W/√3*V*cosφ where I=current in amps, W=power in watts, V=line voltage, cosφ=power factor (this should be on the motor plate, if not you could use 0.9) Regards ninenix
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.
How do you calculate 3ph AC motor power?
To use a single/one phase motor instead of a three phase motor is possible if you have a three phase power supply as you will only need to tap one of the three phases together with neutral and an earthwire, however to use a three phase motor instead of a single phase will require the provision of three phase power supply.
To calculate the phase current of a 10kW 3-phase motor, you can divide the total power (10kW) by the square root of 3 (approx. 1.732) and then divide that result by the line-to-line voltage. The formula is: Phase Current (Amps) = Power (W) / (√3 x Line-to-Line Voltage (V)).
With no three phase power supply you can't use a three phase motor of any kind at all!

power , P=1.732*V*I*power factor so, the formula for calculate the load current for a 3 phase motor is,I=P/(1.732*V*power factor)

For proper working of any 3 phase induction motor it must be connected to a 3 phase alternating current (ac) power supply of rated voltage ...
Your question is a little like asking, 'How long is a piece of string?'! Do the two motors have the same power rating, or are they different?The rate at which energy is used by any machine is defined by its power rating. If the power ratings of two different machines are the same, then both machines use energy at the same rate. So if a single-phase motor has the same power rating as a three-phase motor, then they will both use exactly the same amount of energy over a given period of time.So, if a single-phase motor has a greater power rating than a three-phase motor, then the single-phase motor will the greater amount of energy in a given period. On the other hand, if a three-phase motor has a greater power rating than a single-phase motor, then the three-phase motor will the greater amount of energy in a given period.
You don't. A three phase motor will not start unless it is connected to a three phase supply.
