Laminated rotating electrical machine winding unit for taking windings arranged in grooves includes hollow cylindrical external and internal parts incorporating enclosed grooves each having an opening in their base.

摘要

A winding unit (1) has hollow cylindrical external (2) and internal (3) parts. The external part incorporates enclosed grooves (4) each having an opening (5) in their base. These openings widen at the cylinder edge representing a junction with neighbouring grooves. The internal part's outside shape is adapted to the external part's inside shape. The internal part has divergent heads (6) adjusted towards the openings. These heads have groove recesses in their centre.
