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.

The disclosure relates to a rotating electrical machine (1), in particular an alternator or an alternator-starter for a motor vehicle. At least one bearing mount (48) is provided with at least one opening (49) opening onto the exterior of the bearing mount. A stator (16) comprising an electric coil (18) is provided. This coil includes a plurality of electric conductors, at least one of which includes an end forming an electrical neutral point of the coil. The machine further includes an electrical insulation member (70) configured to prevent any contact between the bearing mount (48) and said neutral point-forming conductor end. The insulation member extends at least partially through the opening of the bearing mount and is at least partially outside the bearing mount. The electrical insulation member being furthermore configured to rest at least partially on an outer surface (71) of the bearing mount.

The invention relates to an alternator for a motor vehicle including a stator (13) equipped with a body (14) carrying several phases each comprising, on the one hand, an inlet (E1 to E′3) and an outlet (S1 to S′3) installed outside the body (14) of the stator (13), and, on the other hand, electrically conducting elements, which are arranged in a network on either side of the body (14) of the stator (13) so as to form a first (12) and a second (12′) bun and which pass through the said body, in which the electrically conducting elements are linked together to form the said networks and connect the inlet of the phase to the outlet of the phase by forming at least one winding. According to the invention, one of the buns (12, 12′), on one side of the body (14) of the stator (13), carries three inlets (E1 to E3–E′1 to E′3), an electrically conducting linking part (50, 51) linking the said inlets electrically together.

A rotary electrical machine for heating a flow of air comprises a primary magnetic circuit suitable for creating a ring of magnetic poles of polarity alternating from pole to pole, and a secondary magnetic circuit suitable for moving relative to the primary magnetic circuit with the circuits being separated by a cylindrical air gap. The secondary magnetic circuit comprises a cylindrical sleeve (1) of laminated ferromagnetic material having a ring of rectilinear notches (4) formed in the vicinity of one of its two cylindrical faces, these notches extending parallel to the axis of the sleeve and being open at both axial ends. Each of the notches receives a zig-zag corrugated copper sheet (6) and the two axial margins (6.sub.3) of each sheet project axially beyond the sleeve and are electrically interconnected with the adjacent margins of the other sheets by two copper rings (8) disposed at opposite axial ends of the sleeve.
