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).

Abstract: A method for terminating and winding coils of a core of a dynamo electric machine. The coils being formed from at least an electric wire and the core having a longitudinal axis. The coils (19) are wound by relatively moving a wire dispenser with respect to a core with relative motions of translation and rotation; at least a stretch of wire extends from the coil; and the stretch of wire is provided with a portion for a termination connection to a termination structure of the core, such as a tang. The method avoids waste cut wire in the apparatus. The core is provided with a groove at an end to receive at least a wire in the path of the wire for the termination of the coils. The apparatus comprises a wire deflector positioned adjacent the end of the core, where the groove is located, in order to intercept and align the wire with the groove. The apparatus can comprise a device for applying torques in two directions on a pulley wheel for feeding wire as a function of the position of the dispenser in the translation and the position of the core in the rotations.
