Abstract (en)
[origin: WO2011117055A2] The invention relates to an electric machine, in particular a starter device (10) for an internal combustion engine. It comprises a noise-optimized toothing system (232, 234) of two gearwheels (22, 25) which can be brought into engagement with one another. The noise-optimized toothing system (232, 234) is configured as an extra-deep toothing system on at least one of the gearwheels (22, 25), which extra-deep toothing system has an asymmetrical toothing profile (214).
