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 present invention relates to an end shield (10) for a rotary electric machine, including one or more feed channels (12) for feeding a coolant supplied from a channel formed in a rotor lamination stack (8) or in a shaft of the rotor or between the rotor lamination stack and the shaft, wherein at least one feed channel (12) has a spray portion (18) for spraying the coolant, said spray portion (18) being placed in the last two thirds of the feed channel (12), when considered in the direction in which the coolant circulates.

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.
