The formula you are looking for is I = kW x 1000/1.73 x E x pf. I = 1.5 x 1000 = 1500. 1500/1.73 x 400 x .86 = 1500/595 = 2.5 amps.
A standard motor's efficiency between 5 to 100 HP is .84 to .91.
A standard motor's power factor between 10 to 100 HP is .86 to .92.
A feeder for a motor has to be rated at 125% of the motors full load amps 2.5 x 125% = 3.1 amps
A #14 copper conductor with an insulation rating of 90 degrees C is rated at 15 amps.
What else can I help you with?
Is it common to use a 4160 V 3 Phase motor with a variable speed drive?
No, a 4160 volt motor with a high inertia load will use a resistor bank in the starting of the motor.
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
Will 220 volt work in a high volt 3 phase motor?
Yes a 208 voltage motor will operate on 220 volts. You have to increase the motor overload protection by 10% of the motor's full load amperage to protect the motor.
Will a 208 volt 3 phase generator supply operate a 230 volt 3 phase motor?
Yes, but the motor's horsepower rating will not be reached.
What is the full load running current of a 3hp 208volt single phase continuous duty ac motor?
It would probably be 20-30 amps. <<>> The electrical code book states a value of 18.7amps for a 3HP 208 volt motor. If the nameplate data is available it is always best to use it when calculating wire size and overload protection for the motor.

Calculate watts for a 4160 volt 55 amp 80 power factor 3 phase motor?
317.025280 KILOWATTS = 317,025.28 WATTS

What is the Amperage of a 20 HP motor at 380 VAC 3 phase 50 Hertz?
20 HP Three phase 360 volt what is the amps
What is 4160 Volt electrical wire insulation rated for?
You can use an insulation rating 5000 volt to run 4160 volt supply.

How do you change a 3 phase 440 volt motor to a 3 phase 220 volt motor?
You can not change it. 440 volt is by design. However you run it with 220 single phase supply, but it would run far lower power.
How do you get a 380 volt 3 phase motor to run on a 220 volt 3 phase power source?
Use a transformer.
On a 220 volt electric motor which is the neutral wire L1 L2 or L3?
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
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.
