why field winding is placed on rotor winding not on stator
winding in case of synchronous machine?

Answer Posted / rajeev

The arrangement of rotor winding and stator winding is
according to rated output of alternator,insulation
consideration of stator and rotor. since for a low voltage
alternator ,rotor (field) is stationary and armature
(stator) rotates. But as output voltage (terminal) increase
accordingly MW POWER,THE SIZE OF ALTERNATOR INCREASE,SO
armature ,which is the single heaviest part of alternator
is made stator ,due to mecanical stress ,insulation problem
cosiderations.but on the counter part rotor is light in
weight as compared to stator.The output can be easily taken
out by stationary armature.
