Saturation Factors for Leakage Reactance of Induction Motors with Skewed Rotors

Expressions for the saturation factors for the leakage reactance of induction motors with skewed rotors are derived. Saturation is taken into account by the effect of the combined slot-, zigzag-, and skew-leakage flux on the permeances of the flux leakage paths. Curves of saturation factors and leakage reactance of a standard motor are compared with test.
