We can select the cable size in sqmm for certain load by
this process
Cross sectional area of conductor in sqmm
In single phase=a=2x4.59PL
Where a=crosssectional area of conductor
P=Load in KW
L=Distance of load point
In three phase=a=4.55xPL/3

I have a drawing of a wound rotor induction motor for a crane. This crane motor has 5 forward speeds & 5 reverse speed implemented of course with different amount of resistance for each speed setting selected. What has got me scratching around is the fact that 8 of the 10 speed selections switch in uneven (unbalanced) amounts of resistances on each of the 3 connections to the motor's rotor.Can this be possible? I would have assumed this would produce unbalanced rotor currents and therefore vibration in the motor. I would greatly appreciate anyone's comments on this. Many thanks, Confused.
