Question { BARC, 11665 }

can a rotating machine give the DC output without commutator?
if yes, how? if no, why?

Answer

here roatating machine may be synronous machine and dc
machine

in case of syncronous machine we use staionary armature and
roataing field to produce A.C
with th same construction production of d.c output is not
possible


in case of d.c machine we prefer roatating armature and
staionary field becasue to produce d.c out put
with a.c consturuction we can not produce becase it raises
comnutator problem for a.c to produce d.c

if we is a.c construction for d.c to produce a.c
genaration of higher voltages are not possible
