there are a transformer and a motor. both are connected to
3phase, 415 Volt, 50Hz power supply. Both are working with
induction principles. Then, why, motor is rotating and
transformer is not rotating.

Even though both works on the same mutual induction
principle,but transformer is a static m/c where as
induction motor is rotating m/c because Indution motors
having rotating magnetic field.
But in the case of T/F, magnetic field generated is satatic
no change in frequency of potential applied, to T/F.
so there is no chance of rotation of T/F.

we are having 15kw and 3kw motor both can run in same time , instead of using copper we are using ug aluminium cable , 35 sq.mm is suitable for its current carrying capacity..?
In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.

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.
