Anyone switching from a combustion engine to an electric drive loses a feature that has previously masked many flaws: acoustic masking. With its broad noise spectrum, the combustion engine masks a wide range of background noises. In an electric drive, this background noise is absent—and as a result, geometric deviations in rotating components at high motor speeds become immediately perceptible as tonalities or vibrations. Particularly affected: the rotor shaft. It is a precision component, subject to high dynamic loads, and combines critical interfaces between the electric motor and the transmission in a single part. In our new blog post, we outline which designs have become established, how monolithic and joined concepts differ, and which interface variants with the transmission are relevant in practice.
