Embodiment Construction

[0024] figure 1An electric machine 10 is shown schematically in FIG. 1 , wherein a rotor 12 is mounted in a stator 13 . The rotor 12 has a rotor shaft 14 , on which a rotor lamination stack 16 is fastened, which consists of individual magnetic steel lamination cores 18 , wherein the corresponding end laminations 19 First and second end faces 40 , 42 of the rotor lamination stack 16 are formed. The magnetic steel laminated core 18 is usually stamped from electrical steel sheets. The rotor core 16 is, for example, pressed against the rotor shaft 14 and fixed thereon in a rotationally fixed manner. A commutator 22 is attached to the rotor shaft 14 around an axial region 20 spaced apart from the rotor lamination core 16 . The commutator is likewise pressed against the rotor shaft 14 , for example in a rotationally fixed manner. An electrical winding 24 , which is electrically connected to a rectifier 22 , is arranged on the rotor core 16 . To this end, the rectifier 22 has re...

Abstract

The invention relates to a rotor and to an electric machine (10), in particular for power-adjusting a mobile part in a motor vehicle, and to a method for producing said type of rotor, having a rotor shaft (14), to which a rotor packet (16) and an axially spaced commutator for receiving a rotor winding (24) is secured, wherein the rotor winding (24) is glued directly by means of an adhesive (50) toselected limited regions of the rotor packet (16).

Description

technical field [0001] The invention relates to a rotor of the type described in the independent claims, an electrical machine comprising the rotor and a method for producing the rotor. Background technique [0002] A direct current motor is known from EP 0 895 668 B1, in which the lamination pack is fixed on the armature shaft. After the laminations have been installed, these laminations are coated with epoxy resin which insulates the armature lamination stack from the winding wires. In this case, the rectifier is pressed axially against the epoxy resin on the armature shaft for its fixing, so that after cooling a form-fitting connection is produced. [0003] DE 19840149 A1 discloses a rotor of an electric machine with a plate stack (Blechpaket) and a current collector (Kollektor), wherein a felt-like element is arranged on the current collector, which is impregnated with a hardenable medium so that The coil wire (Spulendraht) is firmly fixed to the current collector. Fo...
