The invention relates to a stator () which may be used within an electric rotating machine, an electric machine, an apparatus for preparing a stator and a method for preparing a stator. The stator () comprises a stator core () having a plurality of slots () arranged in a circumferential direction (C) of the stator core (). At least a first conductor () and at least a second conductor () are arranged along a radial direction (R) of one slot (). Axial end sections () of the conductors () are electrically connectable or connected and the axial end sections () of radially adjacent conductors () are distanced from each other. The distance () between the proximal end () of the axial end section () of a first conductor () and the stator core () is longer than the distance () between the distal end () of the axial end section () of a second conductor () and the stator core ().

Stator, electric machine, apparatus and method for preparing a stator

The invention relates to a stator which may be used within an electric rotating machine and a method for manufacturing a stator. The stator () comprises a stator core () having a plurality of slots () arranged in circumferential direction (C) of the stator core (), a plurality of conductors () forming a stator winding, wherein at least a radially outer conductor () and a radially inner conductor () are arranged along a radial direction (R) of each slot (). At least one pair of a radially outer conductor () of a first slot () and a radially inner conductor () of a second slot () circumferentially spaced from the first slot () is electrically connected by a connection bridge (). The connection bridge () comprises a first base element () and a second base element () connected to a respective conductor () and a top element () being connected to the base elements () and preferably arranged in a larger distance from the stator core () than the first base element () and second base element ().

Stator, electric machine, connection bridge and method for manufacturing a stator

A method and an apparatus are provided for manufacturing a stator with a plurality of hairpin conductors. For inserting the hairpin conductors () into the slots () of a stator core () a stator core template () is provided. Hairpin conductors () are axially inserted into slots () of the stator core template () such that the hairpin conductor () is arranged at a first position (P) within said slot (). The hairpin conductor () is then moved within said slot () to a different position (P). A complete nest () of hairpin conductors () formed within the stator core template () is then transferred to the stator core ().
