Method for producing stator, in particular for electric motor, and stator and electric machine produced according to such method

The invention relates to a method for producing a stator (14), in particular for an electric motor (13), and to a stator (14) produced by the method and to an electric machine (12) produced by the method, comprising the following method steps: first punching out a T-shaped lamination section (20) of a lamination layer (21) from a sheet metal region completely in an axial direction (8); the lamination section (20) is then pressed back into the initial axial position of the plate region (18) counter to the axial direction (8), a yoke region (24) is punched on the lamination section (20), from which yoke region a tooth (26) extends radially inwards, and wherein the tooth (26) is pressed back into the initial axial position of the plate region (18). According to the invention, the connecting projection (30) of a first lamination section (20) and the corresponding recess (31) of an adjacent second lamination section (20) are designed in such a way that the connecting projection and the corresponding recess form an
