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.
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.
no load means the motor is acting like a coil
3 core 35 sq mm alu. Or 3 core 25 sq mm cup.
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.

Yes the Induction motor works on Electromagnetic induction principle.
For a 26kW, 415V induction motor with a 50m cable run, you would typically need a cable size of at least 6mm^2 to ensure proper voltage drop and current carrying capacity. However, it is always recommended to consult local electrical codes and standards or a licensed electrician to determine the exact cable size needed for your specific installation.
