How can we estimate Gen rotor current?

Answer Posted / k.prakashchandra

Please note that this applies to large generators in which
the field the rotor and there will be two slip rings called
as 'collector rings'. The usage of shunt resistance for
measurement of field current is not possible in brushless
gen

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.
