Abstract
The invention relates to an end turn arrangement in a stator of a dynamoelectric machine. In order to reduce, in a simple fashion, the volume required for the end turns of the form-wound coils, the stator is formed of segments (1) that have a substantially circular arc-shaped cross-section and can be combined into a stator by adding one or more other segments (1) having the same design. Each segment (1) has recesses (6, 7), within which at least one first form-wound coil (3), which is bent outward in the radial direction of the stator in the region of the end turns, and at least one second form-wound coil (4), which is bent inward in the radial direction of the stator in the region of the end turns, are arranged in the form of a tiered winding.
