摘要

The electric motor has a rotor seated on a rotor shaft (4a) rotatably mounted via roller bearings in an earthed stator housing (7a). The rotor shaft is electrically connected to the stator housing via at least one electrically conducting device (12a). The electrically conducting device(s) rests in contact with the rotor shaft via at least one contact part (15a).
