Abstract

A damper, comprising a plurality of blades, a plurality of blade arms, each blade arm coupled to one of the plurality of blades and a motor coupled to one of the blades and one of the blade arms.

Claims

1. A damper, comprising:

a plurality of blades;

a plurality of blade arms, each blade arm coupled to one of the plurality of blades; and

a motor housing coupled to one of the blades or one of the blade arms.

2. The damper of claim 1 wherein the motor housing is directly coupled to one of the blades or one of the blade arms.

3. The damper of claim 1 wherein the motor housing further comprises a shaft, and the shaft of the motor housing is coupled to a frame.

4. The damper of claim 1 wherein the motor housing further comprises a keyed shaft, and the keyed shaft of the motor housing is coupled to a frame through an aperture having a matching shape to the keyed shaft.

5. The damper of claim 1 wherein each of the plurality of blade arms comprises a bearing.

6. The damper of claim 1 wherein each of the plurality of blade arms comprises a first bearing and a second bearing.

7. The damper of claim 1 further comprising a blade shaft coupled to each of the blade arms and configured to transfer torque from a first blade arm of the plurality of blade arms to each of the other plurality of blade arms.

8. The damper of claim 1 further comprising a gearbox coupled to the motor housing and one of the blade arms or one of the blades.

9. The damper of claim 1 further comprising a gearbox coupled to the motor housing and one of the blade arms, wherein the gearbox further comprises a shaft, and the shaft of the gearbox is coupled to a frame.

10. The damper of claim 1 further comprising a support coupled to one of the blades and the motor housing, wherein the support is configured to secure the motor housing to the blade.

11. A damper, comprising:

a frame;

a plurality of blades rotatably disposed in the frame;

a plurality of blade arms, each blade arm coupled to one of the plurality of blades; and

a driver housing coupled to one of the blades or one of the blade arms.

12. The damper of claim 11 wherein the driver housing is directly coupled to one of the blades or one of the blade arms.

13. The damper of claim 11 wherein the driver housing further comprises a shaft, and the shaft of the driver housing is coupled to the frame.

14. The damper of claim 11 wherein the driver housing further comprises a keyed shaft, and the keyed shaft of the driver housing is coupled to the frame through an aperture having a matching shape to the keyed shaft.

15. The damper of claim 11 wherein each of the plurality of blade arms comprises a bearing.

16. The damper of claim 11 wherein each of the plurality of blade arms comprises a first bearing and a second bearing.

17. The damper of claim 11 further comprising a blade shaft coupled to each of the blade arms and configured to transfer torque from a first blade arm of the plurality of blade arms to each of the other plurality of blade arms.

18. The damper of claim 11 further comprising a gearbox coupled to the driver housing.

19. The damper of claim 11 further comprising a gearbox coupled to the driver housing and the blade arm, wherein the gearbox further comprises a shaft, and the shaft of the gearbox is coupled to the frame.

20. A damper, comprising:

a plurality of blades;

a plurality of blade arms, each blade arm coupled to one of the plurality of blades, wherein each of the plurality of blade arms comprises a first bearing and a second bearing;

a blade shaft coupled to each of the blade arms and configured to transfer torque from a first blade arm of the plurality of blade arms to each of the other plurality of blade arms;

a motor housing coupled to one of the blades or one of the blade arms, wherein the motor housing is directly coupled to one of the blades or one of the blade arms, wherein the motor housing further comprises a keyed shaft, and the keyed shaft of the motor housing is coupled to a frame through an aperture having a matching shape to the keyed shaft;

a gearbox coupled to the motor housing and one of the blade arms, wherein the gearbox further comprises a shaft, and the shaft of the gearbox is coupled to a frame; and

a support coupled to one of the blades and the motor housing, wherein the support is configured to secure the motor housing to the blade.
