Answer Posted / mohd.rizwan qureshi
when the full voltage applied to the stator winding ,the
rotor of 3-phase cage induction motor fails tostart.This
happenes whe the no. of stator and rotor slots are equal
or an integral ratio.so due to strong alingment of forces
are produced between stator and rotor at the instant of
starting. these forces create an alingment torque greater
than the accelarating torque.The phenomenon of magnetic
locking between stator and rotor teeth is called cogging or
teethl ocking.
