ABSTRACT
Traditionally, the analyses of induction machines are based on the
simple idealized machine model without skin-effect or/and saturation. These
analyses are based on the assumption that the rotor resistance is constant at
the dc value. Pertinently, this method of analysis usually lead to a very large
error in the torque developed at certain speeds and applied frequencies for
squirrel-cage rotors with deep rotor bar. For the purpose of developing
accurate models for induction machine, this paper aims at modelling the rotor
bar of the induction machine to include the skin effect phenomenon. The
analysis presented in this paper leads to the accurate modelling of induction
machine in dynamic conditions.
Keywords: Induction machine, squirrel-cage rotor, rotor bar, modelling, skin-effect.
