Abstract

An electric motor includes a rotor shaft, a first bearing, and a second bearing. The rotor shaft includes a first rotor shaft part and a second rotor shaft part, the first rotor shaft part being rotatably mounted via the first bearing, and the second rotor shaft part being rotatably mounted via the second bearing. A bellows is connected at its first axial end region to the first rotor shaft part, e.g., by welding, and the bellows is connected at its second axial end region to the second rotor shaft part, e.g., by welding.
