Stator of an electric machine

Abstract

A stator of an electric machine is already known, comprising stator teeth and grooves formed between the stator teeth, in which electrical conductor elements of an electrical individual coil winding are provided as individual coils, wherein an interconnection is provided on at least one end side of the stator, which has a ring section and multiple, in particular a number corresponding to the number of stator teeth, tooth sections protruding from the ring section in the radial direction. The interconnection ring comprises multiple bus bars for interconnecting the electrical individual coils of the electrical winding. The individual coils are produced from a conventional conductor material, e.g. copper. In the stator according to the invention, an electrical winding made of CNT conductor elements is provided. According to the invention: the conductor elements () of the electrical winding are configured as insertable conductor elements () of the electrical winding designed as a plug-in winding; the conductor elements () are each formed of a combination of carbon nanotubes and/or graphene fibres; and at least one electrically non-conductive conductor joining device () is provided on at least one of the tooth sections () of the interconnection ring (), to which two respective conductor ends of two different conductor elements () are electrically connected by means of an electrically conductive joining means.
