what is rotating transformer? what is the uses of it?i mean
applicaitons?
Answer Posted / sam
Rotating Transformer is a device to transfer electrical energy AC from stator to Rotor in AC and opposite/reverse.
Basically, it send AC supply to rotor by AC supply from sec. So its not use brush/slip ring. This rotating transformer is used for synchronous motor mostly. More question u may contact me WA +97433450404

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.
