Abstract

A bent conductor segment (1a, 1b, 1c) for a stator winding of a stator of an electric machine is formed from a bent metal wire and has at least one first straight section (10a, 10b, 10c) with a first free end (11a, 11b, 11c) and a second free end (13a, 13b, 13c). One of the free ends (11a, 11b, 11c, 13a, 13b, 13c) of the conductor segment (1a, 1b, 1c) comprises a hard solder (2a, 2b, 2c) cohesively connected to said free end (11a, 11b, 11c, 13a, 13b, 13c).
