Abstract

A magnet pole, for magnetically levitated vehicles, includes a core (10) and a winding provided with winding disks that are arranged axially on top of each other. Both of the disks contain conduction band sections (6a, 6b) that are wound counter to the direction of winding and in several layers about the core (10). The conduction band sections are connected together in an electrically conductive manner by means of a connection part (1) on the core (10) near ends. The connection part (1) is bent in an outward manner on lateral longitudinal edges that are parallel to each other thus forming a curved outlet (12a, 12b).

Claims

1. A magnet pole for magnetic levitation vehicles the magnet pole comprising:

a core;

a winding, which is wound on the core and comprises two disks located one on top of another, wherein the two disks contain two conduction band sections wound around the core in opposite winding directions and in a plurality of layers; and

a middle connecting part forming a first layer on the core at ends located close to the core, the two conduction band sections being connected to one another in an electrically conductive manner by the middle connecting part forming the first layer on the core at ends located close to the core, wherein the connecting part is bent over to the outside at mutually parallel, lateral longitudinal edges to form bent edge portions, each of said bent edge portions forming an arc-shaped end, said bent edge portions extending in a radially outward direction from said core with respect to a central axis of said core.

2. A magnet pole in accordance with claim 1, wherein the connecting part has two terminal ends, which set the distance between the two disks and are connected to one of the conduction band sections each.

3. A magnet pole in accordance with claim 2, wherein the connecting part is an essentially rectangular, flat shaped part, which has one of the terminal ends each located at opposite ends.

4. A magnet pole in accordance with claim 1, wherein the arc-shaped ends have a somewhat greater length in the circumferential direction of the core than would correspond to the circumference of the core and are placed with an overlap at the ends facing each other.

5. A magnet pole in accordance with claim 4, wherein the overlap of the arc-shaped ends is obtained by an oblique cut of end edges of the connecting part, which said end edges adjoin the end sections.

6. A magnet pole in accordance with claim 1, wherein said lateral longitudinal edges are perpendicular to the central axis of said core.

7. A magnet pole in accordance with claim 1, wherein each of said bent edge portions is arranged at an angle relative to a central axis of said core.

8. A magnet pole for magnetic levitation vehicles the magnet pole comprising:

a magnet core;

a winding arrangement comprising two conduction band sections wound around the core in opposite winding directions and in a plurality of layers;

a middle connecting part between said magnet core and said two conduction band sections to form a first layer on the core, said middle connecting part connecting said two conduction band sections to one another in an electrically conductive manner, wherein said connecting part comprises two arc-shaped ends extending radially outwardly from said core, each of said two arc-shaped ends comprising a bent portion, said bent portion being bent at an angle relative to a central axis of said core.

9. A magnet pole in accordance with claim 8, wherein the connecting part has two terminal ends, which set a distance between the two conduction band sections, each of said two terminal ends being connected to one of said conduction band sections.

10. A magnet pole in accordance with claim 8, wherein said arc-shaped ends have a greater length in a circumferential direction of said core than a corresponding circumferential length of said core and said arc-shaped ends having overlapping circumferential ends.

11. A magnet pole in accordance with claim 10, wherein the overlap of said arc-shaped ends is obtained by an oblique cut of an end edge of said connecting part, which each said end edge adjoins the end sections.

12. A magnet pole in accordance with claim 8, wherein said connecting part is an essentially rectangular flat shaped part that is wrapped about said core and which has a terminal end located at opposite circumferential ends.

13. A magnet pole for magnetic levitation vehicles the magnet pole comprising:

a magnet core;

a winding arrangement comprising two conduction band sections wound around the core in opposite winding directions and in a plurality of layers; and

a middle connecting part between said magnet core and said two conduction band sections to form a first layer on the core, said middle connecting part connecting said two conduction band sections to one another in an electrically conductive manner, wherein said middle connecting part comprises a middle connecting portion and two arc-shaped ends, said middle connection portion being connected to said two arc-shaped ends, each of said two arc-shaped ends extending radially outwardly from said core with respect to a central axis of said core, wherein a distance between said core and said two arc-shaped ends is greater than a distance between said core and said middle connecting portion.

14. A magnet pole in accordance with claim 13, wherein the connecting part has two terminal ends, which set a distance between the two conduction band sections, each of said two terminal ends being connected to one of said conduction band sections.

15. A magnet pole in accordance with claim 14, wherein said connecting part is an essentially rectangular flat shaped part that is wrapped about said core and which has a terminal end located at opposite circumferential ends.

16. A magnet pole in accordance with claim 14, wherein the overlap of said arc-shaped ends is obtained by an oblique cut of an end edge of said connecting part, which each said end edge adjoins the end sections.

17. A magnet pole in accordance with claim 14, wherein each of said two arc-shaped ends comprise a bent portion, said bent portion being bent at an angle relative to a central axis of said core, said bent portion facing in a radial outward direction with respect to said central axis of said core.

18. A magnet pole in accordance with claim 14, wherein said middle connecting portion is substantially parallel to the central axis of said core.

19. A magnet pole in accordance with claim 13, wherein said arc-shaped ends have a greater length in a circumferential direction of said core than a corresponding circumferential length of said core and said arc-shaped ends having overlapping circumferential ends.
