A rotary electric machine includes a stator with a stator winding, a rotor with a field winding supported for rotation about a rotation axis relative to the stator, and an excitation winding. The excitation winding is fixed relative to the rotor and is electrically connected to the field winding. The rotor defines a coolant channel having an inlet and an outlet. Liquid coolant enters the inlet and flows outwardly through a portion of the excitation winding to conduct heat away from the excitation winding. Generators, aircraft electrical systems, and methods of cooling rotary electric machines are also described.
