Abstract

A stator for an electrical machine includes a stator yoke and a plurality of stator coils arranged on the stator yoke. An interconnection arrangement is arranged on one end face of the stator yoke. The interconnection arrangement has connecting conductors which are electrically insulated from one another. The connecting conductors are arranged concentrically with respect to one another and each have a different diameter. The connecting conductors have connections for the ends of the stator coils and for connection to the electrical machine. To minimize the space requirement of the stator and simultaneously allow the stator coils to be automatically interconnected in an automated manner, the interconnection arrangement is arranged inside an area bounded by the stator coils. Furthermore, the connections for the ends of the stator coils include connection projections designed such that they project outward at an angle to the respective connecting conductor to attach the stator coil ends. A number of cutouts are provided in the connection conductors and are arranged so that the connection projections are bendable into the cutouts once the coil ends have been connected.
