Use this formula to find amperage when kW is shown. Amps = kW x 1000/1.73 x Volts x pf. Use a power factor of .85 for the formula. Once the current is calculated re-ask the question for cable size for the calculated current.
A single conductor per phase will use a 3/0 copper conductor supplying 180 amps for 80 meters on a 400 volt three phase system. A 3/0 copper wire with an insulation rating of 75 and 90 degrees C is rated at 200 and 210 amps respectively.
How to calculate a cable size of 3kw motor
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
At 2965 rpm it sounds like an induction motor for a 50 Hz supply. A 45 kW motor would draw about 55 kW from the supply with a power factor of 0.85, so that is 65 kVA, and on a 415 v 3-phase supply that is a current of 90 amps. For armoured XLPE cale the size needed is at least 16 mm2 Probably 25 mm2 would be preferred for a permanent installation but it would depend on how the cable is installed, how much free air movement there is around it etc.
cable size for the 90kW motor is 3CX150sqmm aluminum cable
Into units of what?
Sir, what is the cable size for 1.5kw 3phase induction motor 400v?
This wouldn't be on a farm would it? 1000' line would need it's own utility pole, and transformer.
How to calculate a cable size of 3kw motor
no load means the motor is acting like a coil
how will you start 3phase inuction motor using star delta stater
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
To answer this question the voltage of the motor must be stated.
Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.
the three phase dc motor never seen yet motor eaither 3phase m/r or dc motor.

Then it is not a three phase motor.
