Crawling in an induction motor is caused by low supply
voltage, high loads, development of harmonics in the rotor,
possibly even design faults. Crawling can be caused when a
small change in load results in an angular displacement of
the rotor field with respect to the stator field a bit
similar to the synchronous motor operation. The effects of
crawling can be reduced by avoiding certain combinations of
stator and rotor slots or altering the position of rotor
bars(skewing).
