摘要： The present invention relates to an apparatus (200) for pre-assembling a winding for electric machine stator or rotor which includes a plurality of hairpins (255) with two legs (255a, 255b) having non-circular cross- section. It comprises a ring (220,230), including a plurality of slots (222,232), as well as an outer containment ring (210) acting in containment along the perimeter of the ring (220,230). Furthermore, an inner cam block (270) and an outer cam block (280), surrounding and radially facing the inner cam block (270), are arranged opposite to the exit face of said ring (220.230). The cams are adapted to be crossed, in use, by said two legs (255a, 255b) when they cross said ring (220.230) at the same time; the cams opens into a free circular space (295) between the two cam blocks. The invention also relates to a method of pre-assembling a winding set (290) for electric machine stator or rotor, in which the hairpins are inserted in sequence in the slots of the apparatus (200), and successive rotations of the ring (220,230) are made to obtain the finished winding set (290) positioned in the free circular space.
