Abstract

A stator for an electric machine having an annular lamination stack with a longitudinal axis and slots extending along the longitudinal axis, at least three electrical phases, each of which has two partial strands, a plurality of rings connected in series to form a partial strand, a plurality of connection wires arranged to form a ring in adjacent layers of the slots, and a power connection for electrically connecting the stator. The connection wires are connected by pairs at a contacting side of the lamination stack for connecting adjacent layers at contacting areas. The power connection is arranged at the contacting side, and the connection wires are closed in each instance at an opposed contacting side opposite the contacting side.
