Answer / lova subrahmanyam

the motor can't produce torque because there is no back emf
induced in the open ckt .due to this no rpm

Answer / sunil guru

if the circuit is complete current flows completely and
more flux is produced so EMF thus torque is produced.....
and if the rotor conductors are kept open then torque cant
be produced without torque rotor cant run....

Answer / deepankar

There will be no
current in rotar circuit
and hence rotar does
not rotate at all.

Because of no back
emf the total applied
voltage will lead to a
very high current in
statar windings making
a probability of burning
of statar windings.
