In this paper, a study of the starting performance of induction machines with aluminium and copper casted rotors is presented. Models are developed to predict the starting current. Based on measurements of inter-bar resistivity, an analytical model is used to predict the influence of inter-bar currents on machine starting performance and stray-load losses. The results are verified by measurements. It is found that the inter-bar currents increase the pull-out torque in the aluminium rotor, but at the expense of increased stray-load losses.
