Abstract

A method for producing a stator (20) of an electric machine is provided. The method includes providing a stator (20) with at least one stator slot (22) that is bounded by two stator teeth. The method proceeds by introducing electrical conductors (30) into the at least one stator slot (22). At least one conductor (30) has an expandable coating (25) applied partially to its surface. The method continues by activating the expandable coating (25) to bring about an expansion of the coating (25), as a result of which the conductors (30) are fixed within the stator slot (22).
