Abstract: The present disclosure relates to a covering, such as a casing, for a component of an electrical drive system. Components of this kind are, for example, the electric motor or the inverter of an electric motor. Both the inverter and the electric motor itself generate noise at high frequencies, for instance between 6 kHz and 12 kHz, due to the switch elements used in them. These noises should not escape to the exterior because they are disruptive in terms of both frequency and volume. The present disclosure shows a cover for absorbing these noises, that is cost-effective and can be arranged close to the electric motor and its components.
