Abstract:

Embodiments of a heat exchanger for cooling endwindings in a rotary electric machine are provided herein. In some embodiments, a heat exchanger may include a body configured to be disposed proximate the rotor endwinding and coupled to a casing and end shield of the rotating electric machine. The body defines a cavity configured to capture a heated fluid expelled from the rotor endwinding. A channel, having a cooling fluid therein, is formed in the body and fluidly coupled to a heat sink. A rotating electric machine and method for cooling endwindings in a rotating electric machine are disclosed.
