Embodiment Construction

[0032] Figure 1a A conventional segment 100 for a stator 200 (not shown) or a rotor 210 (not shown) of an electric machine 300 is shown in two views, which may consist of a thin electrical connection having a thickness of 0.5 mm or, for example, 0.35 mm. Tablets (Elektroblech) Composition. Other strengths (or thicknesses) of the lugs are likewise possible. An x-y and an x-z ​​coordinate system are shown for the orientation, which should indicate the geometrical orientation of the segment 100 .

[0033] Segment 100 has a plurality of teeth 10 and is preferably formed from punched sheets which are first punched and then pressed into groups of punched sheets in the form of segment 100 . Alternatively, it is also possible to produce the tooth 10 by means of a casting process, ie to cast it. The length of the punched segment 100 is related here to the structural length of the electric machine 300 in the axial direction. It can be seen that in the segment 100 in the axial direct...

Abstract

The invention relates to a segment (100) of a stator (200) or a rotor (210) of a motor; the segment comprises mutually connected teeth (10) of limited number; each teeth comprises a groove (11) and a key (12); opposite sides of the segment are provided with at least one key zone (110) and at least one groove zone (120) in an axial direction of the motor.

Description

technical field [0001] The invention relates to a segment of a stator or rotor of an electrical machine. The invention also relates to a method for producing segments of a stator or a rotor of an electric machine. Background technique [0002] Known lamination packs for electric machine stators comprise a single segment comprising teeth, pole pieces and yoke. In this case, the punched sheet pack forms a plug-in system which has protrusions on one side and recesses on the other side. The individual segments are wound with the aid of a flyer winding machine and subsequently plugged together to form the completed stator. [0003] The disadvantage is that the winding can only be carried out very inflexibly with the known stator segments, wherein high demands are placed on the flying fork winding machine. Contents of the invention [0004] It is therefore the object of the present invention to provide an improved segment of a rotor or a stator of an electric machine. [000...
