Apparatus and method for manufacturing a partial nest or a nest of conductors

An apparatus for manufacturing an at least partial nest of pin conductors for forming a stator, the apparatus comprising a stator core template, wherein:

• the stator core template comprises a block body provided with radially extending ribs, said ribs forming slots therebetween for insertion of legs of the pin conductors;
• the apparatus further comprises at least one ring element arranged to provide an outer radial abutment face for inserted pin conductors;
• the at least one ring element comprises a separate ring connected to the ribs;
• and
• the separate ring is attached to shelf elements, which are connected to the ribs.

A method for manufacturing an at least partial nest of pin conductors for forming a stator, comprising:

• providing an apparatus for manufacturing an at least partial nest of pin conductors for forming a stator, the apparatus comprising:
• a stator core template with a block body provided with radially extending ribs forming slots in between for insertion of legs of the pin conductors, and
• at least one ring element being arranged to provide an outer radial abutment face for the legs of inserted pin conductors;
• inserting at least one pin conductor into at least one of said slots of the stator core template such that said pin conductor is arranged at a first position within said slot, wherein in said first position the pin conductor is arranged differently than in the in-tended position in the stator core template;
• moving said pin conductor within said slot of said a stator core template from said first position to a second position;
• repeating, for at least one additional pin conductor, the providing the apparatus and the inserting at least one pin conductor into at least one of said slots of the stator core template, to form a first layer of an at least partial nest of pin conductors;
• and
• removing the at least partial nest of pin conductors from the stator core template.
