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.
What happens if the Capacitive Voltage Transformer Primary neutral is not earthed. There is a CVT between Transformer and source, and the CVT neutral of the transformer is not earthed, does it effect the transformer while charging or does it effect the transformer charging process.
