An alternator having a rotor and a stator is described. The stator includes a cylindrical body with a plurality of phases. Each of the plurality of phases includes a phase input located at least partially outside of the cylindrical body, where the phase input is formed of a bar. The bar includes a longitudinal surface extending along at least a part of the bar, a first segment crossing the cylindrical body, and a second segment extending from an axial side of the cylindrical body. Each of the plurality of phases further includes a phase output located at least partially outside of the cylindrical body and conducting elements crossing the cylindrical body and forming at two axially opposite sides of the body, respectively, a first chignon and a second chignon. The conducting elements are electrically connected to form at least one winding connecting the phase input to the phase output.

The invention relates to a device for gripping and transferring a ring of electrical conductors in the form of pins which are used to produce a winding, such as a pin winding. The gripping device (C) is designed to seize the ring from a first element, such as a ring-forming element, and to transfer same into a second element (B), such as an element used to insert the ring into the member that supports the winding to be produced. The inventive device comprises a control cone (19) which can be moved axially inside a frame (13) for contact with levers (15) which are pivot mounted to the frame, such that the levers pivot when the cone is moved. The winding-production system is characterized in that it comprises an autonomous gripping and transfer device (C) which can be separated from the above-mentioned first and second elements (B) and which can be positioned on same in a pre-determined reference position. The invention can be used to produce a stator for an electrically-rotating machine.

A machine for configuring the winding head of a stator for a rotary electrical machine, which includes U-shaped conductors which are inserted axially into axial slots in the stator body, is of the type comprising a support body together with concentric tubular sleeves. The lower axial end part of each sleeve includes gripping means. The gripping means of each sleeve consist of a set of gripping slots, each of which has a right angled profile in circumferential and axial cross section. Each of these slots receives the free end portion of one conductor, so that rotation of a sleeve produces a single bend at the open end of the axial slot for each conductor in the associated layer of conductors in the stator.
