In a dynamoelectric machine having an annular stator core and a cylindrical rotor for concentric rotation therein, and defining a gap region between the rotor and the stator core, a baffle disposed in the gap region includes a shell member which circumferentially surrounds the rotor and includes a respective radial outwardly extending annular flange member at both its inner and outer axial end. An annular plate at the outer axial end abuts the axial outer flange and is radially adjustably secured to the stator. The axial inner flange comprises a flexible material, such as silicone rubber, and engages the stator in gas flow sealing relationship. An outer second passage disposed between the baffle and the stator is axially sealed off from the gap region by the flexible flange, thereby diverting gas in the outer passage to at least one coolant passage in the stator.
