Rotor wedge with arms
First Claim
1. A wedge for use in a generator rotor comprising:
- a wedge body extending for an axial length that is greater than an axial length of a first pole and a second pole of the generator rotor, the wedge body having a generally triangular cross-section and extending between a first end and a second end;
a first side of the wedge body extending for the axial length between the first end and the second end of the wedge body;
a second side of the wedge body extending for the axial length between the first end and the second end of the wedge body and having a generally flat surface;
a third side of the wedge body extending for the axial length between the first end and the second end of the wedge body and having a generally flat surface;
a first arm extending circumferentially away from the wedge body at an interface between the first side and the second side and extending axially along the wedge body; and
a second arm extending circumferentially away from the wedge body at an interface between the first side and the third side and extending axially along the wedge body,wherein the first arm and the second arm extend continuously for an axial length that is less than the axial length of the wedge body with the axial length of the first arm corresponding to an axial length of the first pole of the generator rotor and the axial length of the second arm corresponds to an axial length of the second pole of the generator rotor.

15. A rotor for a generator comprising:
-
a shaft; a rotor core radially outward from the shaft and having a plurality of poles spanning axially along the rotor core; a plurality of windings wrapped around each of the plurality of poles; and a plurality of wedges, each wedge being positioned between two adjacent poles of the plurality of poles, each wedge comprising; a wedge body having a generally triangular cross-section and a length that extends axially along a length of the rotor core that is greater than a length of the plurality of poles; and two arms extending circumferentially away from the wedge body in opposite directions and axially along the wedge body, the two arms configured to each interact with one of the two adjacent poles such that a part of each of the two arms is radially within a portion of one of the two adjacent poles, wherein the two arms of each wedge extend an axial length of the wedge body that is equal to an axial length of each of the two adjacent poles. - View Dependent Claims (16, 17, 18)
