Abstract

The present disclosure relates to an interconnection assembly for a stator of an electrical machine. The interconnection assembly comprises a shaped bus bar, which has a first region, which comprises a connection point of the interconnection assembly for an external connection, a second region, in which a connecting point for forming a connection of the bus bar to a stator winding is formed, and a central region, which connects the first region and the second region. The first region and the second region are arranged in parallel planes. The central region is oriented in such a way that an angle of a transition between the first region and the central region and an angle of a transition between the second region and the central region deviate from a right angle. The disclosure also relates to a stator having an interconnection assembly.
