Abstract

A rotating electrical machine includes: a frame including a first housing portion for housing an electronic component and a second housing portion formed integrally with the first housing portion for housing a rotator and a stator; and a bracket including a first communicating hole communicating with the first housing portion and a second communicating hole communicating with the second housing portion.

Claims (22)

1. A rotating electrical machine comprising:

a frame including a first housing portion for housing an electronic component and a second housing portion formed integrally with the first housing portion for housing a rotator and a stator; and

a bracket including a first communicating hole communicating with the first housing portion, a second communicating hole communicating with the second housing portion, and a third housing portion for housing a detector for detecting a rotation angle of the rotator, the first communication hole connecting the first housing portion and the third housing portion, the second communication hole connecting the second housing portion and the third housing portion.

2. The rotating electrical machine according to claim 1 ,

wherein the frame includes a first end face adjacent to the first and second housing portions, and

wherein the bracket is attached so as to cover the first end face.

3. The rotating electrical machine according to claim 2 , wherein the first end face is substantially orthogonal to the rotation axis of the rotator.

4. The rotating electrical machine according to claim 1 , wherein the first and second communicating holes are arranged substantially parallel to one another.

5. The rotating electrical machine according to claim 1 ,

wherein the first communicating hole guides a cable for the detector connected to the detector to the first housing portion.

6. The rotating electrical machine according to claim 1 , wherein the bracket includes a side wall for surrounding the detector.

7. The rotating electrical machine according to claim 1 , wherein the frame includes a first refrigerant passage provided between the first housing portion and the stator.

8. The rotating electrical machine according to claim 7 , wherein the frame includes:

an inner wall having a shape corresponding to a shape of an outer periphery of the stator;

an outer wall provided outside the inner wall; and

a second refrigerant passage provided between the inner wall and the outer wall.

9. The rotating electrical machine according to claim 8 , wherein the second refrigerant passage extends along the rotation axis of the rotator.

10. The rotating electrical machine according to claim 1 , wherein the frame includes:

an inner wall having a shape corresponding to a shape of an outer periphery of the stator;

an outer wall provided outside the inner wall; and

a refrigerant passage provided between the inner wall and the outer wall.

11. The rotating electrical machine according to claim 10 , wherein the refrigerant passage extends along the rotation axis of the rotator.
