Abstract (en)
[origin: WO2020048864A1] The invention relates to a tooth-wound coil (6) of a stator (3) or of a stator segment (25) of a dynamo-electric machine having - two straight sections (14) spaced apart from each other and running substantially parallel, and two 180° brackets (15) located on the ends thereof, wherein the straight sections (14) have an active part area (13), the axial extend of which is less than or equal to that of the straight section (14), - wherein the tooth-wound coil (6) has a symmetrical extension plane (16) running in the longitudinal direction, - wherein an insulation material (9) is provided around the straight sections (14) of the tooth-wound coil (6), which material effects groove isolation and or phase isolation in the stator (3) or stator segment (25).
