Abstract
The invention relates to an electric motor (10) having a casing (12) and a rotor (18) which has a rotor shaft (26) with an axis (A), wherein the rotor shaft (26) is guided outside the casing (12), by means of one of its ends, through an opening (28) which is provided in a wall (30) of the casing (12) that extends at a right angle to the axial direction (A) and with which a bearing element (38) is associated, wherein the bearing element (38) bears the rotor shaft (26) such that it can rotate. According to the invention, the bearing element (38) is received in a depression (32) that is made in the wall (30) that extends at a right angle to the axial direction (A), wherein a damping element (54) is provided between a peripheral wall of the depression (32) and the bearing element (38). The invention further relates to a motor/gear unit (10/58) and a variable-length drive means having an electric motor (10) of this kind.
