Abstract: The rotating electric machine (1) having a housing comprising first (14) and second (15) clamp members and an inner face, a stator comprising a stator body (41) clamped between the first and second clamp members and having an outer face extending opposite the inner face together defining an annular cooling chamber (21) surrounding the stator body, the stator body comprising a longitudinal stack of stator sheets (410), each stator pack of which comprises an annular core having an outer circumference and at least two radially centrifugal protuberances projecting from the outer circumference of the annular core, in the annular cooling chamber, and diametrically opposite one another, the stator sheets of the longitudinal stack being identical and two adjacent stator sheet of the longitudinal stack being angularly offset from each other such that the respective protuberances thereof do not extend opposite one another.

Abstract: Rotor (30) for a rotary electric machine, including: at least one permanent magnet (1) having, in cross section, at least one large side (2a) and at least one small side (3a), a rotor body (33) including stacked sheets, the rotor body (33) including at least one recess (4) receiving the permanent magnet (1), the recess (4) being delimited by at least one face (5a) opposite the large side (2a) of the permanent magnet (1), at least one sheet (6) including at least one deformable tongue (7) connecting to the face (5a) of the recess (4) and extending into the recess (4), the deformable tongue (7) being angled and including a foldable portion (8) configured to be pressed against the small side (3a) of the permanent magnet (1).

Abstract: The invention relates to a rotary electric machine with liquid cooling, comprising a rotor with permanent magnets and a wound stator, the rotor comprising: (i) at least one rotor sheet stack, (ii) magnets housed in the sheet stack, and (iii) front and rear flanges adjacent to the sheet stack, the machine being configured to enable a cross-flow of the cooling liquid within the rotor sheet stack.
