Modeling of Inductances Considering Bar Harmonics and Temperature to Accurately Predict Output Torque of an Induction Motor

Equivalent circuit parameters of an induction motor are highly susceptible to various undesired factors. These phenomena primarily include effects of higher order time and space harmonics, temperature, magnetic saturation, and skin-effect. Traditional approaches model these equivalent circuit parameters via temperature, iron saturation, and slotting effects. However, the impacts of harmonic fields generated by the spatial magnetomotive force …
