Abstract
A method and an apparatus are provided for manufacturing a stator with a plurality of hairpin conductors. For inserting the hairpin conductors (15, 15) into the slots (11) of a stator core (12) a stator core template (22) is provided. Hairpin conductors (15) are axially inserted into slots (21) of the stator core template (22) such that the hairpin conductor (15) is arranged at a first position (P1) within said slot (21). The hairpin conductor (15) is then moved within said slot (21) to a different position (P2). A complete nest (20) of hairpin conductors (15) formed within the stator core template (22) is then transferred to the stator core (12).
Claims8
An apparatus for manufacturing a stator with a plurality of hairpin conductors arranged in slots of a stator core, the apparatus comprising:
- a stator core template comprising a body having a closed annular shape which is provided with a number of radially and axially extending slots corresponding to the number of slots of the stator core, said slots of the stator core template having at least one of a circumferential width larger than the circumferential width of the slots of the stator core or a radial length larger than the radial length of the slots of the stator core;
- an insertion station for inserting at least one hairpin conductor into at least one of said slots of the stator core template such that said hairpin conductor is arranged at a first position within said slot, wherein in said first position the hairpin conductor is arranged differently than in an intended position in the stator core;
- and
- a moving station for moving said hairpin conductor within said slot of said stator core template from said first position to a second position.
