Abstract

A winding support ( 1 ) for an electric machine ( 100 ), having multiple pole teeth ( 10 ), wherein each pole tooth ( 10 ) has a tooth shank ( 14 ) around which at least one winding can be arranged, and wherein a tooth shank ( 14 ) has an increasing width of the tooth shank ( 14 ) in an axial direction ( 3 ) of the winding support ( 1 ) proceeding from an axial face side of the winding support ( 1 ). At least one tooth shank ( 14 ) has an increasing or decreasing width in or counter to the radial direction ( 5 ) of the winding support ( 1 ).

Claims (16)

1. A winding support ( 1 ) for an electric machine ( 100 ), having multiple pole teeth ( 10 ), wherein each pole tooth ( 10 ) has a tooth shank ( 14 ) around which at least one winding can be arranged, and wherein the tooth shank ( 14 ) has an increasing width of the tooth shank ( 14 ) in an axial direction ( 3 ) of the winding support ( 1 ) proceeding from an axial face side of the winding support ( 1 ), characterized in that the tooth shank ( 14 ) has an increasing or decreasing width in a radial direction ( 5 ) of the winding support ( 1 ).

2. The winding support ( 1 ) according to claim 1 , characterized in that at least one tooth shank ( 14 ) has an increasing width axially toward a center of the tooth shank ( 14 ) proceeding from the axial face sides of the winding support ( 1 ).

3. The winding support ( 1 ) according to claim 1 , characterized in that the winding support ( 1 ) has a base element ( 20 ), and in that the base element ( 20 ) has a circumferential region ( 22 ) on which the pole teeth ( 10 ) are arranged so as to project in or counter to the radial direction ( 5 ) of the winding support ( 1 ).

4. The winding support ( 1 ) according to claim 1 , characterized in that the winding support ( 1 ) is assembled from individual elements which have in each case one pole tooth ( 10 ) and which, when assembled, form the winding support ( 1 ).

5. The winding support ( 1 ) according to claim 3 , characterized in that the width of at least one tooth shank ( 14 ) increases or decreases in or counter to the radial direction ( 5 ) of the winding support ( 1 ) proceeding from the base element ( 20 ).

6. The winding support ( 1 ) according to claim 1 , characterized in that the winding support ( 1 ) is embodied as a laminated core which is assembled from multiple sheet-metal laminations.

7. The winding support ( 1 ) according to claim 6 , characterized in that individual sheet-metal laminations have, in the region of at least one tooth shank ( 14 ), an increasing or decreasing width in or counter to the radial direction ( 5 ) of the winding support ( 1 ).

8. The winding support ( 1 ) according to claim 6 , characterized in that individual sheet-metal laminations of a tooth shank ( 14 ) have an increasing width proceeding from the axial face sides of the winding support ( 1 ).

9. The winding support ( 1 ) according to claim 6 , characterized in that individual sheet-metal laminations of the laminated core are of similar form.

10. The winding support ( 1 ) according to claim 1 , characterized in that the pole teeth ( 10 ) have pole heads ( 16 ) which have a greater width than the tooth shanks ( 14 ) at their widest point.

11. The winding support ( 1 ) according to claim 1 , characterized in that the width of at least one tooth shank ( 14 ) increases or decreases in or counter to the radial direction ( 5 ) of the winding support ( 1 ) proceeding from a tooth head ( 16 ) arranged on said tooth shank.

12. A stator ( 120 ) having a winding support ( 1 ) according to claim 1 .

13. A rotor ( 110 ) having a winding support ( 1 ) according to claim 1 .

14. An electric machine ( 100 ) having a winding support ( 1 ) according to claim 1 .

15. The winding support ( 1 ) according to claim 1 , characterized in that the winding support ( 1 ) has a base element ( 20 ), and in that the base element ( 20 ) has a substantially circularly running circumferential region ( 22 ) on which the pole teeth ( 10 ) are arranged so as to project in or counter to the radial direction ( 5 ) of the winding support ( 1 ).

16. The winding support ( 1 ) according to claim 6 , characterized in that individual sheet-metal laminations of the laminated core are of identical form.
