An apparatus () for deforming conductors of at least one winding assembly (), protruding from a side of a stator or of a rotor () of an electric machine. The at least one winding assembly () comprises a plurality of basic conductors () comprising at least one leg inserted into cavities () of stator or rotor (), each having at least one respective free or terminal end (). The apparatus () comprises at least one twisting matrix () adapted to rotate about an axis (X), comprising at least one gripping element () adapted to grip at least one free end () and adapted to be moved in radial direction with respect to said axis (X). The apparatus comprises at least one guide () adapted to guide the at least one gripping element () along the radial direction with respect to the axis (X); and a radial actuator (), adapted to put in motion the at least one gripping element () along the radial direction with respect to the axis (X).

Apparatus for deforming conductors protruding from a side of a stator or of a rotor of an electric machine

An apparatus for pre-assembling a winding for an electric machine stator or rotor includes a plurality of hairpins with two legs having non-circular cross-section, a ring including a plurality of slots and an outer containment ring acting in containment along the perimeter of the ring. An inner cam block and an outer cam block, surrounding and radially facing the inner cam block, are arranged opposite to the exit face of the ring. The cams are adapted to be crossed, in use, by the two legs when they cross the ring at the same time; the cams open into a free circular space between the two cam blocks. A method for pre-assembling a winding set for an electric machine stator or rotor is also provided. Hairpins are inserted in sequence in the slots of the apparatus. A finished winding set positioned in the free circular space is obtained by successive rotations of the ring.

Apparatus and method for pre-assembling winding sets of a winding bar for electric machine stator or rotor

An assembly for assembling a winding group of a bar winding for an electric machine is provided. The winding group includes a plurality of bar conductors, each bar conductor having a first leg, a second leg and a bridge portion connecting the first leg to the second leg, and being shaped so that the first and second legs are mutually spread by a predetermined distance. The assembly includes an annular fixture delimiting a plurality of slots, each slot receiving at least one portion of either the first leg or the second leg, a guiding device defining an annular containment housing, receiving at least partially the first and second legs of the plurality of legs of the plurality of bar conductors that are housed in the plurality of slots, forming at least one radial containment wall for the first and second legs.
