Support structure for laminated core of stator segment

Abstract

The invention relates to a support structure (17) for a laminated core (9) of a stator segment (13) of a dynamoelectric machine having an external rotor, the support structure (17) having two joint plates (5) and two curved pressure plates (1), the respective longitudinal faces of which are in each case mutually opposed, and which encompass a predefinable space and can be connected at their abutting edges. The support structure also has substantially radial bars or ribs (3) between the pressure plates (1) and at least one element having polygonal cut-outs, which element is connected to a longitudinal face of the ribs (3) and forms a base plate of the support structure (17).

Description

technical field [0001] The invention relates to a load-bearing structure of a lamination pack of a stator segment of an external rotor generator, a stator segment, a stator, an external rotor generator, a wind power generator, and a Stator segment or stator manufacturing method. Background technique [0002] In large electrical machines, especially slow-running torque motors and generators, it is advantageous if the laminated core of the stator is not produced as a single piece. The laminated core of the stator is therefore constructed in segments, that is to say in segments, which are subsequently assembled on the stator to form a closed ring. [0003] In large wind turbines with a direct drive from the outer rotor, the individual stator segments are mounted by screwing such stator segments onto flanges connected to the machine installation chamber of the nacelle of the wind power plant. A segmented design of a stator with an inner rotor is known, for example, from the do...

AI Technical Summary

Problems solved by technology

[0004] A disadvantage of these embodiments, however, is the mechanical complexity involved in achieving a stable fixation of the stator segments and the stator in the nacelle

This is especially disadvantageous in the nacelle of a wind power plant, since adequate fastening can only be achieved with a corresponding mechanical outlay and thus additional weight.
