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.
How do you wire a 4160 volt motor?
Wiring a 4160-volt motor involves connecting the motor's terminals to a compatible power supply and ensuring proper grounding. Start by ensuring that all power sources are turned off, then connect the three-phase power lines to the motor's terminals, typically labeled U, V, and W. Make sure to follow the motor's wiring diagram for correct connections and phase orientation. Finally, secure all connections, double-check for any loose wires, and ensure proper grounding before restoring power to the system. Always consult local electrical codes and regulations.
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.

How many poles are required on motor starters for the following motors a240-volt single-phase induction motor b440-volt three-phase induction motor?
For a 240-volt single-phase induction motor, a two-pole motor starter is typically required, as it connects to the two live conductors of the single-phase supply. For a 440-volt three-phase induction motor, a three-pole motor starter is needed, as it connects to the three phases of the three-phase supply.

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.
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.
