In synchronous generators field is rotor and armature is stator.Can we take the output at the rotor..

Answer / sdvyas

Yes,electricity can be generater in either case.
However,due to high voltage 6.6 KV/11 KV it is much more
safe to kept HV on stator. Further, if we take HV on the
rotor, rotor will have more mass as the total curent will
be carried out by HV windings only. It will also give more
thrust on the bearings.

Therefore, it is safe and reliable to have field windings
on the rotor part of the generator. Brushless exciter is
the best choice for any syncrogenerator.

Answer / nithi

yes, we can.There two types of synchronous generator
1,rotor as a field 2,stator as a field.
so,what u have asked is come under the 2'nd category.
but,generally second one is not adopted in practical due
to various technical issues.

sir , what happen if we decrease ( approx 3 inch ) the lenth of shaft in 110KW Induction , three phase motor. actually a 110KW motor is couppled with star couplling to 120TR compressor. When we doing maintenance in compressor it is required to skid the motor backword and resulting dis- alightnment . so we want to change the tyre coupling in place of existing coupling. so it is required to cut off the rotor aprox 3 inch form driving side.
