The rotor (4) has a flow grid (30a,30b) positioned within the flow channel (30) provided by the annular gap between the inner edge of a rotor cap plate (22) and a rotor shaft (28). The flow grid has at least 2 stages, provided by an initial delay grid (30b), with a pressure generation characteristic and a delay grid (30a) with a deflection characteristic, adjacent the rotor winding head (29). |
