In iduction motors the current is higher than normal for
both the cases when the voltage appllied is more than the
rated as well as less than the rated, why?

Answer Posted / prakash

In induction motor torque is directly proportional to square of current. Therefore if voltage is less than to maintain torque slip is increases , impedance decreases and current increases also when voltage increases than all magnetizing component of current increases so current increases.

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.
