Title: STATOR FOR AN ELECTRICAL MACHINE
Abstract:
Stators for an electrical machine (1) are already known which comprise stator slots (2) and conductor elements which are arranged in said stator slots (2) and each of which have two conductor ends (3, 3.1), wherein two adjacent conductor ends (3, 3.1) of two conductor elements are each connected, by means of a welded joint extending across the end faces of the conductor ends (3, 3.1) in question, to one another without the use of an additional material. According to the invention, at least one of the conductor ends (3, 3.1) of at least one of the welded joints (5) has, beneath the welded joint (5) in question, a projection which projects towards the other conductor end (3, 3.1).
