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

Rotary electrical machine with optimised cooling

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 () delimited by an outer wall () that belongs to one of the parts of the casing () and is made of a moldable material such as aluminium; and an inner wall () belonging to a steel part () which is thinner than the outer wall () and shaped so as to have a region () for mounting the stator body and two docking regions () each having a seal () by virtue of their arrangement on either side of the mounting region () of the stator body.

Rotary electric machine cooled by a heat-transfer fluid

An electrical rotating machine includes a stator () provided with teeth () around which a group of coils () is wound, an annular interconnector () resting on a stator lamination stack () provided with tongues () to which ends () of the coils () are welded for the formation of phases (U, V, W) of the electrical machine, and a closure flange () for closing a housing () for receiving the stator (). The machine also includes at least one damper () consisting of a deformable material, configured to be mounted so as to be compressed between the interconnector () and the closure flange () of the machine. The invention also relates to the corresponding damper.
