Abstract :
Based on finite element models of a squirrel cage induction motor, on the frequency domain analysis of steady state motor operation and on the step by step in time domain analysis of the transient of electromagnetic field, dynamics and transient heating of the rotor, this paper represents an almost complete evaluation of the influence of the shape of rotor bars cross-section on motor operation characteristics. The evaluation of the rotor heating transient during the motor in-load start-up through a dedicated multiphysic model reflects three coupled phenomena - transient electromagnetic field, rotor dynamics and transient rotor heating.
