the no of stator&rotor slots are equal in quantity,then the
flux producing each are same so the rotor&stator are runs
with same speed after little some time motor stops rotating
that means motor is stops automatically.they are locking
each other then it will be refused to run. this is
cogging/teeth locking.
the rotor rotates below the sy.speed,i.e (one seventh speed
of sy.speed),this effect cause by the harmonics).this cause
by 3rd harmonic,this is crawling
