Answer Posted / damodarreddy
in case of motor the secondary winding is rotor.if there is
no short circuit in rotor,rotor winding is not a closed
circuit i.e open circuit.in open circuit voltage wil develop
but there is no current flows in the rotor winding it causes
the rotor doesnt rotate.
according to faradays laws of electro magnetic induction
when ever a current carrying conductor is placed in a
magnetic field the conductor will try to rotate.
if there is no short ckt,no cuurrent in winding and then how
to rotate.hence secondary (or) rotor of a motor is short
circuited.
in my point of view
