At very low speed rotor flux oppose the stator flux

Answer / dbh

Armature reaction only occurring in alternator

Answer / manoj

to produce armature rection,there is must neccessary two
opposite direction field and one uni direction field,so that
only the the air gap flux will distorts.in induction motors
the field produced in rotors is opposite with armature flux
in one direction only that means only on top of the
conductors produce torq .

Answer / ravikant soni

there is no any concept of armature reaction in three phase induction motor because in three phase induction motor the field due to the rotor rotate in same direction as of the stator with same speed that is with synchronous speed and hence no armature reaction is possible in induction motor
