  • Publication number: 20240356418
    Abstract: A system and a method for inserting I-pins into a stator or rotor winding assembly are provided. The system has a cylindrical containment for hairpins and a circular inner containment axially inserted into the cylindrical containment for hairpins having a set of radial slots, an upper circular plate with one or more upper cam recesses, a lower circular plate with one or more lower cam recesses, and a vertical wall extending from the upper circular plate to the lower circular plate and rotatably mounted relative thereto. The upper and lower cam recesses accommodate a leg of the I-pins. The vertical wall has one or more voids positioned so that, upon rotation of the vertical wall with respect to the upper and lower circular plates, the upper and lower outlets lead into the voids releasing the leg in a radial slot of the cylindrical containment for hairpins.

  • Patent number: 11962206
    Abstract: A device for modeling hairpins promoting insertion of winding sets of the hairpins on a stator or rotor to allow an increased filling of the slot space in an assembly of winding sets on the stator or rotor is provided. Application relates to electric stators or rotors, and any device using electric wires having any gauge.

  • Publication number: 20240106309
    Abstract: An apparatus for assembling a winding of hairpins is provided. The apparatus has a feeding section, an insertion section into a winding assembly cylinder, and a handling section having at least two arms configured so that when the end of one arm faces the feeding section, the end of the other arm faces the insertion section. Each arm has a gripper for picking and releasing a hairpin, the gripper being slidingly mounted along an extension direction of the corresponding arm. The insertion section has an assembly drum moved by a rotary mechanism, both mounted on the same axis, perpendicular to the rotation axis of the arms. The assembly drum has a series of inserts on its outer surface defining a series of radially open slots, the rotary mechanism being sized to leave free space between the arm and the slots. A method for assembling a winding of hairpins is also provided.

  • Publication number: 20220037970
    Abstract: An apparatus (200) for deforming conductors of at least one winding assembly (100), protruding from a side of a stator or of a rotor (114) of an electric machine. The at least one winding assembly (100) comprises a plurality of basic conductors (102) comprising at least one leg inserted into cavities (115) of stator or rotor (114), each having at least one respective free or terminal end (108, 110). The apparatus (200) comprises at least one twisting matrix (202, 203) adapted to rotate about an axis (X), comprising at least one gripping element (204) adapted to grip at least one free end (108, 110) and adapted to be moved in radial direction with respect to said axis (X). The apparatus comprises at least one guide (206, 207) adapted to guide the at least one gripping element (204) along the radial direction with respect to the axis (X); and a radial actuator (208), adapted to put in motion the at least one gripping element (204) along the radial direction with respect to the axis (X).
