摘要
A brush device (1) for electrically connecting a first element (2A) to a second element (2B) that can rotate relative to the first element (2A) about a rotational axis (L). In order to make electrical contact with the second element (2B), in a contact area (1A), the brush device (1) has a structure (1 B, 11B′, 1B″) that extends helically relative to the rotational axis (L). An E-machine (2) has a brush device (1) of this type, and a drive device has such an E-machine (2) for electrically driving a motor vehicle.
