Wet-running permanent magnet rotor e.g. for centrifugal pump, has first hub part with outer bounding surface enclosed by second hollow hub part with inner bounding surface to form flow channels

摘要

The device has at least one flow channel (5) with an entry whose distance from the rotation axis of the rotor is less than that between its outlet and the rotation axis. The rotor has a first hub part (9) with an outer bounding surface enclosed by a second hollow hub part (10) with an inner bounding surface. The bounding surfaces have flow channel contours forming the flow channel(s).
