FIELD: electrical engineering.
SUBSTANCE: winding unit (8) comprises sections (3a, 3b, 3c … 3n) arranged in axial direction at a distance from each other and electrically connected to form a series circuit. Winding conductor (2) is wound from inner end (5a, 5b, 5c … 5n) to outer end (6a, 6b, 6c … 6n) of corresponding section (3a, 3b, 3c … 3n), increasing section (3a, 3b, 3c … 3n) in radial direction. At least one section (3a, 3b, 3c … 3n) at its outer end (6a, 6b, 6c … 6n) is electrically connected to inner end (5a, 5b, 5c … 5n) of next in axial direction sections (3a, 3b, 3c … 3n). At least one next axial section (3a, 3b, 3c … 3n) of the winding forms stepped region (10a, 10b, 10c … 10n), in stepped area inner end of section (5a, 5b, 5c … 5n) is located in radial direction at height of external end (6a, 6b, 6c … 6n) sections (3a, 3b, 3c … 3n), with which it is electrically connected.
EFFECT: technical result consists in improvement of efficiency of manufacturing due to reduction of distances between sections.
