DC series motor is used in traction. DC series motor
produces high torque at low speed, which is required during
starting of train as it (Train) has got high inertia at
starting.
Three phase induction motor is also used in high speed
train e.g. RAJDHANI EXPRESS.

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.
