Embodiment Construction

[0038] according to figure 1 , the motor has a stator 1 and a rotor 2. The rotor 2 has a rotor shaft 3 and a rotor lamination 4 . The rotor shaft 3 is mounted in bearings such that the rotor shaft 3 and with it the entire rotor 2 can rotate about the axis of rotation of the electric machine.

[0039] If the terms “axial”, “radial” and “tangential” are used below, they always refer to the axis of rotation 6 . The term “axial” refers to a direction parallel to the axis of rotation 6 . The term “radial” refers to a direction perpendicular to the axis of rotation 6 towards or away from the axis of rotation 6 . The term “tangential” refers to a direction perpendicular to the axis of rotation 6 and to the radial direction, ie a direction that circles around the axis of rotation 6 at a constant radial distance from the axis of rotation 6 .

[0040] usually based on figure 1 As shown, the rotor 2 is arranged radially inside the stator 1 . The electric machine is thus designed as...

Abstract

A rotor (2) of an electric machine has a rotor core (4) connected in a rotationally fixed manner to a rotor shaft (3). Viewed in the direction of the axis of rotation (6) of the rotor plate stack (4), the rotor plate stack (4) runs from the first axial end face (7) of the rotor plate stack (4) to the second end face (7) of the rotor plate stack (4). The axial end face (8) extends. The rotor stack (4) has receptacles (10) distributed around the rotor axis (6), which, viewed in the direction of the axis of rotation (6), extend from a first axial end face (7) to a second axial end face (8) EXTENSION. In each case a tensioning screw is inserted into the receptacle (10), which, viewed in the direction of the axis of rotation (6), protrudes beyond the axial end faces (7, 8). A fastening element (12) is arranged on the tensioning screw (11) at both axial end faces (7, 8), so that the rotor laminations (9) of the rotor lamination stack (4) are pressed against one another. A fan (18) is arranged on the tensioning screw (11) at the first axial end face (7) of the rotor core (4).

Description

technical field [0001] The invention relates to a rotor of an electric motor, [0002] - wherein the rotor has a rotor lamination that is connected in a rotationally fixed manner to a rotor shaft of the rotor, [0003] - wherein, seen in the direction of the axis of rotation of the rotor lamination stack, the rotor lamination stack extends from a first axial end face of the rotor lamination stack to a second axial end face of the rotor lamination stack, [0004] - wherein the rotor lamination pack has receptacles distributed around the rotor, which receptacles extend from the first axial end face to the second axial end face, viewed in the direction of the rotor axis [0005] - wherein, in each case, a tensioning screw is inserted into the receptacle, the tensioning screw protruding beyond the axial end face, viewed in the direction of the axis of rotation. [0006] - wherein the fastening element is mounted on the tensioning screw at both axial end faces. [0007] The inve...
