support structure, stator and stator segment of a dynamoelectric machine, external rotor generator or external rotor motor, wind power installation, and processes for manufacturing a stator segment and a stator

摘要

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 bent pressure plates (1), the respective longitudinal faces of which are in each case mutually opposed, and which comprise a predefined space and can be connected at their contact edges. the support structure also has substantially radial bars or ribs (3) between the pressure plates (1), and at least one element having polygonal cutouts, which element is connected to a longitudinal face of the ribs (3) and forms a plate base of the support structure (17).
