Abstract
Modular field windings including multiple coils are provided about a rotor core. Axially spaced spacers maintain the coils circumferentially spaced from one another, the spacers and coils defining radially directed openings in the rotor. Flow directing elements are disposed in the openings to maintain constant or increased flow velocity of cooling gas in a radial outward direction along passages between the elements and the coils to maintain or increase the heat transfer coefficient, thereby enhancing the cooling effect of the gas flow on the turns.
