Abstract (en)
[origin: WO2022017653A1] The invention relates to a stator (2) for a housing-free dynamoelectric rotary machine (1). The stator (2) has a material layer structure (8), wherein the material layer structure (8) has a plurality of material layers (6), and the material layers (6) are arranged in a row along a rotational axis. The material layer structure (8) has a plurality of thickened areas (9, 10) and a plurality of grooves (5, 7), one groove (5, 7) being arranged between two thickened areas (9, 10). The invention additionally relates to a housing-free dynamoelectric rotary machine (1), having such a stator (2), wherein an end element (14) is arranged at at least one axial end (50, 51) of the stator (2), and the end element (14) is connected to the stator (2) by means of at least one connection element (16).
