The present disclosure relates to a rotating electromechanical apparatus including a ring-cylindrical ironless stator arranged adjacent to the inner surface or outer surface of a casing, respectively, which stator includes a continuous hairpin winding having two layers; a method for manufacturing the continuous hairpin winding comprising folding-over a ribbon of a plurality of wires successively to form a flattened helical ribbon, bending, into each wire of the flattened helical ribbon a straight segment, thereby forming a flattened quasi-helical ribbon, and rolling the flattened quasi-helical ribbon into a cylindrical shape to form a cylindrical continuous hairpin winding, with the straight segments running substantially parallel to a cylinder axis of the cylindrical shape; and a folding apparatus for manufacturing the continuous hairpin winding.
A rotating electromechanical apparatus comprising:
