The acoustic noise and the mechanical behavior of electrical machines gain significance day by day. Applying electrical machines such as induction machines with squirrel-cage rotors (IMs) as power-steering drives in automotive applications requires very strict constraints for the behavior of the motor for both electromagnetic and mechanical means. Therefore, it is of particular interest to analyze the machine's behavior in both means, depending on the technical faults that are caused by manufacturing processes and unavoidable mechanical tolerances. The studied IM is a mass series product and does not allow for expensive manufacturing. Hence, the impact of the technical faults must be estimated and contained. Finite-element models allow for a structured but complex analysis of these tasks.
