Abstract (en)
[origin: WO2016078691A1] A cylindrical multiphase coreless winding with hexagonal loops (2) is disclosed, preferably comprising two sections for each phase and having a symmetrical layout, said layout being such that a cross section of the winding according to a plane perpendicular to the main axis away from crossing regions of the loops comprises one or more concentric layers of cross-sectional areas (7) containing the loops of different phases, and that a cross section of the winding according to at least a second plane located in a crossing region of loops comprises one or more concentric layers of areas (8)containing a uniform distribution of loops of two phases.
