Answer / sandeepraj

the stator acts as an inductor,heat will be generated dur to internal resistance

Answer / nur.asidik

in practice, stator will heat up because of losses,

Answer / aju

Since the stator winding has sufficient reactance, it will
not burnout and nothing will happens...

Answer / vijay

Mr. Gajanan, then motor why not burnt when rotor is
inserted, whats the cause between rotor inserted and rotor
out????

Answer / vijay c

TO Aju, if wdg has sufficient reactance then motor should
never burnt or it should never takes more than rated
current.
Think deeply

Answer / dhiren

it wiii definately burnt due to not transfering the power
from stator.

Answer / jagadesh

To gajanan & everybody in this discussion,

It will not burn but simply heated and makes humming sound as usual ,

if you short circuit the coil,then high current will pass through it,it will leads to burning(Similar to s.c of an Indutor)...

Answer / vasuram

it acts as a transformer

Answer / shahul snfa

if we give the supply to the stator. the motor will consume
reactive power from the supply to produce working flux. and
the absence of rotor makes those flux into leakage flux and
sent to ground

Answer / gajanan

winding will burn due to short circuit

why scott connection is done why not two phases are directly picked at the output of 3 phase transformer??
