Answer / ajith

since there is no alternating current the dc current impenge
at the same point hence the single point will heated,and burn.

Answer / sameer

and dc doesn't produce
alternating flux and
not a frequency
term,and resistance of
field and armature is
less it carry toooo
much current so
winding is burn out

Answer / r.murugesh

The ac motor have input alternating both +ve and -ve cycle the dc supply only one +ve cycle so does't work in dc supply

Answer / r.suresh babu

The AC motors are haveing a less resistance so,it will be
operates in only AC supply.In case of by giving DC supply
field windig is burn,after that motor is damaged.
