Rotary electric machine, with fluid distribution chamber between stator and housing

A rotary electric machine, comprising

• a rotor configured for coupling with a rotary shaft;
• a stator configured for surrounding the rotor, the stator comprising a stator body and stator end windings extending from axial ends of the stator body;
• and
• a housing configured for receiving the stator and rotor,
• wherein a fluid distributing chamber provided along an inner surface of the housing for being communicated with a plurality of fluid channels so as to distribute the fluid to flow through outer surfaces of the stator body and the stator end windings when the stator is inserted into the housing, the fluid distributing chamber being delimited by an annular groove on the inner surface of the housing surrounding the stator in a circumferential direction,
• wherein a first set of the plurality of fluid channels is formed by a first outer surface of the stator and by a plurality of slots circumferentially spaced and provided with the housing on a first axial side of the annular groove, the plurality of slots being configured for directing the fluid to flow through a first stator end winding via outlets of the plurality of slots,
• wherein a second set of the plurality of fluid channels is formed by a plurality of recesses arranged between the stator body and the housing, the plurality of recesses extending axially parallel to an axis of the rotary electric machine and being circumferentially spaced and provided onto at least one of the outer surface of stator body and the inner surface of the housing on a second axial side of the annular groove, the plurality of recesses being configured for directing the fluid to flow through a second stator end winding via outlets of the plurality of recesses, and
• wherein the outlets of the plurality of slots are radially inward of the outlets of the plurality of recesses.
