Abstract

A motor for driving a fan in a heating and/or cooling system includes a motor body, a motor cover, and an isolator. The isolator damps vibrations passed from the motor body to the motor cover. The isolator includes two isolating elements connected by a bridge. At least one of the two isolating elements includes at least two corners in a cross-sectional view.

First claim

What is claimed is:

1. A motor for driving a fan in a heating and/or cooling system, the motor comprising:
a motor body;
a motor cover; and
an isolator for damping vibrations passed from the motor body to the motor cover,
wherein the isolator includes two isolating elements connected by a bridge, a cross-sectional shape of a first of the two isolating elements being a mirror image of a cross-sectional shape of a second of the two isolating elements, each of the two isolating elements including at least two corners spaced from the bridge in a cross-sectional view, and one of the at least two corners on the first of the two isolating elements being separated from one of the at least two corners on the second of the two isolating elements by a bracket supporting the motor body within the motor cover, and
wherein at least one of the two isolating elements is an X-shaped prism, a cross-shaped prism, a cube on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half, a cuboid on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half, or a rectangular prism on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half.

2. The motor of claim 1 , wherein at least one of the two isolating elements is a cube, a cuboid, or a rectangular prism, having eight corners and six faces.

3. The motor of claim 1 , wherein at least one of the two isolating elements is the X-shaped prism or the cross-shaped prism.

4. The motor of claim 1 , wherein at least one of the two isolating elements is the cube, the cuboid, or the rectangular prism on the lower half and the prism having rounded corners and the rounded recess separating the rounded corners on the upper half.

5. The motor of claim 1 , wherein at least one of the two isolating elements is a cube, a cuboid, or a rectangular prism having a plurality of rectangular projections along a top side and a plurality of rectangular recesses separating the plurality of rectangular projections.

6. The motor of claim 5 , wherein the at least one of the two isolating elements includes three rectangular projections along the top side.

7. The motor of claim 1 , wherein at least one of the two isolating elements is a cube, a cuboid, or a rectangular prism having a plurality of cube, cuboid, or rectangular prism projections along a top side and a plurality of rectangular recesses separating the plurality of projections.

8. The motor of claim 7 , wherein the at least one of the two isolating elements includes nine cube, cuboid, or rectangular prism projections along the top side.

9. The motor of claim 1 , wherein the bridge connects opposing inside faces of the two isolating elements and has a square, a rectangle, a circular, or an elliptical cross-section.

10. The motor of claim 1 , further comprising a flange extending radially from the motor body, the motor cover connecting to the flange and cooperating with the flange to support the motor body, wherein the isolator is arranged horizontally between an outer surface of the motor body and an inner surface of the motor cover or an inner surface of the flange on opposing sides.

11. The motor of claim 10 , further comprising at least one bracket having a leg extending orthogonal to the motor body, the at least one bracket including a slot, wherein the bridge is clamped within the slot and supported by the at least one bracket.

12. An isolator configured to for damp vibrations in a motor of a heating and/or cooling system, the isolator comprising:
two isolating elements; and
a bridge connecting opposing inner faces of the two isolating elements, wherein at least one of the two isolating elements including at least two corners in a cross-sectional view, and
wherein at least one of the two isolating elements is an X-shaped prism, a cross-shaped prism, a cube on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half, a cuboid on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half, or a rectangular prism on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half.

13. The isolator of claim 12 , wherein at least one of the two isolating elements is a cube, a cuboid, or a rectangular prism, having eight corners and six faces.

14. The isolator of claim 12 , wherein at least one of the two isolating elements is the X-shaped prism or the cross-shaped prism.

15. The isolator of claim 12 , wherein at least one of the two isolating elements is the cube, the cuboid, or the rectangular prism on the lower half and the prism having rounded corners and the rounded recess separating the rounded corners on the upper half.

16. The isolator of claim 12 , wherein at least one of the two isolating elements is a cube, a cuboid, or a rectangular prism having at least three rectangular projections along a top side and at least two rectangular recesses, with one rectangular recess separating two of the at least three rectangular projections.

17. The isolator of claim 12 , wherein at least one of the two isolating elements is a cube, a cuboid, or a rectangular prism having a plurality of cube, cuboid, or rectangular prism projections along a top side and a plurality of rectangular recesses separating the plurality of projections.

18. The isolator of claim 12 , wherein the two isolating elements are the same.

19. The isolator of claim 12 , wherein the bridge connects opposing inside faces of the two isolating elements and has a square, a rectangle, a circular, or an elliptical cross-section.

20. A motor for driving a fan in a heating and/or cooling system, the motor comprising:
a motor body;
a motor cover; and
an isolator for damping vibrations passed from the motor body to the motor cover,
wherein the isolator includes two isolating elements connected by a bridge, a cross-sectional shape of a first of the two isolating elements being a mirror image of a cross-sectional shape of a second of the two isolating elements, and
wherein at least one of the two isolating elements is an X-shaped prism, a cross-shaped prism, a cube on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half, a cuboid on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half, or a rectangular prism on a lower half and a prism having rounded corners and a rounded recess separating the rounded corners on an upper half.
