Spacer and method for producing an active rotor section of an electrical machine

摘要

The distance piece (1) has rod casings (3), and an external supporting ring (2) for surrounding the casings. An inner supporting ring (7) encloses a rotational axis of a rotor active part, where one of the casings is connected with the inner ring over a positioning rod (10) that runs radially with respect to the rotational axis. The casings comprise an air conducting rod (5) in an area that is turned towards the rotational axis, and a transversely-running stabilizing rod (4) is arranged in an inner area of the casings. An independent claim is also included for a method for manufacturing a rotor active part of a dynamo-electrical machine.
