Abstract
Cooling assemblies and methods, including, for example, at least one bar (e.g., electrically insulated and/or thermally conductive bar(s)), members (e.g., i-beams, rectangular members, and the like), stator laminations, rotor laminations, and/or combinations thereof, such as those configured to cool electric machines (e.g., electric motors and generators).
Claims8
A cooling assembly for an electric machine, comprising:
- a rotor core comprising a plurality of laminations and having:
- a first end;
- a second end;
- a bore extending from the first end to the second end of the rotor core and configured to accommodate at least a portion of a rotor shaft, the bore characterized by a longitudinal axis;
- an end plate disposed at the first end;
- and
- an end plate disposed at the second end;
- where at least some laminations in the plurality of laminations comprise at least one opening positioned at least between the first end and the second end of the rotor core;
- and
- at least one bar disposed in the at least one opening, where the at least one bar is electrically insulated from the at least some laminations.
