Effect of skewing slots on flux distribution in induction machines

Abstract

Although skewing is practically the rule for all but the largest induction motors, its effect on the flux distribution has received little attention. It is shown by experiment that the effect of skewing can be very significant and results in a poorer performance. Some of the advantages which are commonly believed to accrue from the use of skew are fictitious if a proper choice of slot combination is made; these are discussed.
