Abstract

A coil support structure including a coil spacer, a yoke spacer, and a support formed between the coil spacer and the yoke spacer. And the support has laterally protruding parts.

Claims (38)

1. A coil support structure including:

a coil spacer;

a yoke spacer that is connected to the coil spacer; and

a support formed between the coil spacer and the yoke spacer, wherein

the support has laterally protruding parts that protrude away from the support along a first and a second direction that are orthogonal to one another,

the laterally protruding parts that protrude in the first direction contact the coil spacer, and

the laterally protruding parts that protrude in the second direction do not contact the coil spacer.

2. The coil support structure according to claim 1 , wherein the support has a recess interposed between the laterally protruding parts.

3. The coil support structure according to claim 1 , wherein the laterally protruding parts are formed in an alternating fashion around a perimeter of the support.

4. The coil support structure according to claim 1 , wherein the coil spacer has a first area that contacts the support and a second area that does not contact the support.

5. The coil support structure according to claim 4 , wherein the support is symmetrical along at least two directions.

6. The coil support structure according to claim 1 , wherein one of the laterally protruding parts defines a plane perpendicular to a rotating axis of the rotor, the protruding part defines a trough hole, and the trough hole has an axis that extends in a direction of the rotating axis of the rotor.

7. The coil support structure according to claim 6 , wherein the one of the laterally protruding parts has two or more plate shape partition walls, and the two or more plate shape partition walls are normal to the coil spacer.

8. The coil support structure according to claim 6 , wherein the one of the laterally protruding parts has two or more plate shape partition walls and the two or more plate shape partition walls are incident against the coil spacer between the middle of the coil spacer and an edge of the yoke spacer.

9. The coil support structure according to claim 6 , wherein an axis of the through hole is inclined relative to the rotating axis of the rotor.

10. The coil support structure according to claim 1 , wherein the support defines a through opening configured to receive a bolt that fastens the support.

11. The coil support structure according to claim 10 , further comprising: a second through opening, wherein

the first and second through openings are arranged such that a line passing thorough a center of the first and second through openings also passes through a middle of the laterally protruding parts.

12. An electrical rotation machine comprising:

a stator;

a rotor movable about the stator;

a coil support structure mounted between magnetic field poles of the rotor, the coil support structure including:

a coil spacer,

a yoke spacer that is connected to the coil spacer, and

a support formed between the coil spacer and the yoke spacer, wherein

the support has laterally protruding parts that protrude away from the support along a first and a second direction that are orthogonal to one another,

the laterally protruding parts that protrude in the first direction contact the coil spacer, and

the laterally protruding parts that protrude in the second direction do not contact the coil spacer.

13. The electrical rotation machine according to claim 12 , wherein the support has a recess interposed between the laterally protruding parts.

14. The electrical rotation machine according to claim 12 , wherein the laterally protruding parts are formed in an alternating fashion around a perimeter of the support.

15. The electrical rotation machine according to claim 12 , wherein the coil spacer has a first area that contacts the support and a second area that does not contact the support.

16. The electrical rotation machine according to claim 15 , wherein the support is symmetrical along at least two directions.

17. The electrical rotation machine according to claim 12 , wherein one of the laterally protruding parts defines a plane perpendicular to a rotating axis of the rotor, the protruding part defines a trough hole, and the trough hole has an axis that extends in a direction of the rotating axis of the rotor.

18. The electrical rotation machine according to claim 17 , wherein the one of the laterally protruding parts has two or more plate shape partition walls, and the two or more plate shape partition walls are normal to the coil spacer.

19. The electrical rotation machine according to claim 17 , wherein the one of the laterally protruding parts has two or more plate shape partition walls and the two or more plate shape partition walls are incident against the coil spacer between the middle of the coil spacer and an edge of the yoke spacer.

20. The electrical rotation machine according to claim 12 , further comprising a pole shoe that makes up a head of a magnetic field pole, wherein

a height of two adjacent coil support structures is different, and

the height is a distance between the laterally protruding parts and the pole shoe.
