Abstract (en)
[origin: WO2019179558A1] The invention relates to a connection (1) of cylindrical windings of an electric motor with "n"-busbars (2) in order to produce interconnections between the individual windings, wherein the busbars (2) are geometrically arranged in three planes (3,4,5), wherein a plane (5) is defined as a concentric layer relative to the winding and follows a constant radius, wherein busbars (2) on the same plane (3) cross that busbar (2) on the other plane (4).
