Abstract
A new stator core cooling concept is provided that can be implemented with a conventional core structure having cooling ducts interspersed at intervals along the axial length of the stator core. To enhance cooling of the stator coils, the cooling ducts are radially closed off so that cooling air is forced to flow circumferentially, preferably through small holes, channels, or slots, to impinge directly on the armature bar surface. Accordingly, rather than flowing cooling gas through the cooling ducts and immediately discharging it into the annular gap between the rotor and stator, cooled gas flows radially down through the cooling duct and then must flow circumferentially whereupon it impinges directly on the armature bar surface itself.
