Abstract: A tooth-wound coil of a stator or of a stator segment of a dynamo-electric machine having two straight sections spaced apart from each other and running substantially parallel. Two 180° curves are located on the ends thereof, wherein the straight sections have an active part area, the axial extend of which is less than or equal to that of the straight section. The tooth-wound coil has a symmetrical extension plane running in the longitudinal direction. An insulation material is provided around the straight sections of the tooth-wound coil. The material effects groove isolation and/or phase isolation in the stator or stator segment.
