Abstract

The invention relates to a stator (2) for an axial flow machine, comprising a plurality of stator teeth (7) having a tooth body (8) and a yoke element (11), and comprising multiple coil windings (10), wherein the yoke element (11) consists of a rolled lamination stack, in which recesses are arranged in which the tooth bodies (8) of the stator teeth (7) are arranged or which form the tooth bodies (8) of the stator teeth (7).
