Abstract: An interconnector having circular conductors for a stator of a polyphase rotary electric machine including a body having a winding provided with a plurality of coils each having input and output ends, the interconnector comprising a first portion including at least three circular conductors having an annular shape stacked axially on top of one another and electrically isolated from one another, and a second portion including at least one electrically insulated circular conductor having an annular shape. The first and second portions are intended for being installed on either side of the body of the stator. The circular conductors of the first portion and the circular conductors of the second portion have, on the inner periphery thereof, tabs projecting inwardly for welding the input ends and the output ends of the coils, respectively.

Abstract: The invention relates mainly to a rotary electrical machine including: a bearing (12); a stator (11) including a stator body (13); and a tubular ring (27), said stator body (13) being mounted braced in the ring (27); a cooling chamber (28) for circulating coolant liquid defined by an outer periphery of said tubular ring (27) and an inner periphery of said bearing (12); said bearing (12) including an intake and an outlet of coolant liquid, said machine including a separating wall (42) for separating said cooling chamber (28) extending between said intake and said outlet of coolant liquid, said separating wall (42) being added relative to said tubular ring (27) and including at the ends thereof attachment members for holding said wall (42) on said tubular ring (27).

Abstract: One aspect of the invention relates to an electrical connection device comprising: an internal connection member surrounding an axis X having a plot, and a plurality of connectors; a first external connection member surrounding the axis X and being stacked axially with the internal connection member, comprising a plot, and a plurality of connectors; the device being characterized in that each plot has a wavy shape forming troughs comprising internal troughs situated facing the axis X and external troughs situated on an external periphery, each connector of the internal connection member being connected in an internal trough of the plot of the internal connection member and each connector of the first external connection member being electrically connected in an external trough of the plot of the first external connection member.

Abstract: The invention relates to a rotary electric machine which comprises: a stator provided with a body; a casing in at least two parts; an annular chamber for cooling the machine (30) delimited by an outer wall (23) that belongs to one of the parts of the casing (2, 3) and is made of a moldable material such as aluminium; and an inner wall (31) belonging to a steel part (31) which is thinner than the outer wall (23) and shaped so as to have a region (33) for mounting the stator body and two docking regions (22, 24) each having a seal (36) by virtue of their arrangement on either side of the mounting region (33) of the stator body.
