Abstract
A symmetrical cooling system for an electric rotor machine that includes a passageway that is positioned between portions of the stator, and which provides a pathway for a cooling medium. Stator ducts positioned within the stator, or portions thereof, are in fluid communication with the passageway. Cooling medium may flow through the stator ducts from the passageway to ends of the stator so that the cooling medium only travels along a portion of the overall axial length of the stator. The symmetrical cooling system also includes an air gap that is positioned between the stator and the rotor, and which receives cooling medium from the passageway at a midsection of the air gap. Cooling medium received at the midsection of the air gap may then flow towards either first or second ends of the stator.
