Abstract
Induction motor equivalent circuits, as well as improved mathematical models, taking into account the magnetizing curve
nonlinearity, the phenomena of hysteresis and eddy currents, have been proposed. Induction motor static, power and dynamic characteristics
have been researched taking the mentioned phenomena into consideration. A harmonic analysis of induction motor currents under no-load
conditions has been carried out. It has been demonstrated that taking magnetizing curve nonlinearity into account in the mathematical model
results in coincidence of characteristics obtained at the mathematical model and experimental curves. The eddy currents losses increase
influence on induction motor characteristics has been shown. The adequacy of the proposed mathematical model has been confirmed by
experimental research.
