Abstract

A dynamo-electrical machine includes a stator and a rotor rotatable relative to the stator about an axis of rotation, the stator and/or the rotor having a plurality of segments arranged one after another in a rotational direction of the rotor, the segments each having opposing ends facing in opposite rotational directions, and being provided with flanges on the opposing ends, with respective flanges of neighboring ones of the segments in confronting relationship, each of the flanges having at least one hole oriented in the rotational direction, the at least one hole of at least one of the respective confronting flanges having an internal thread and threadably receiving a sleeve having an external thread, the respective confronting flanges being spaced apart by the sleeve, wherein a screw is received through the at least one hole of the one of the respective confronting flanges and through the sleeve and engages in the at least one hole of the other one of the respective confronting flanges, thereby exerting a force on the one of the respective confronting flanges, and connects the respective confronting flanges to each other via the sleeve.
