Electric motors are important machines for generating mechanical energy. The general trends of their operation, especially in the automotive industry, are increasing rotational speeds and temperatures. The aim of this task is to determine the resistance of a rotor with an aluminum cage to centrifugal load at elevated temperatures. We use the Abaqus environment to simulate mechanical loads. The results present the critical stresses and displacements and the phenomenon of plasticity at different temperature loads. Critical rotational speeds are determined and geometry optimization is proposed.
