An electric machine comprises a stator (1) and a rotor (5) rotatably disposed within the stator. At least the rotor and windings (3) of the stator are sealingly enclosed by an end shield (12) arranged at each axial end of the machine in a space (16) filled with gas. Wafters (18) are arranged on the rotor for mixing gas trapped in said space. A member (30) is arranged in said space (16) for directing gas moved by the wafters (18) at least partially radially towards the radial periphery of the space for mixing this gas with gas in a peripheral portion of said space. |
