Document Type and Number:
WIPO Patent Application WO/2013/136021
Kind Code:
A3
Abstract:
The invention relates essentially to an assembly of flanges (55, 56) for supporting at least one stack of laminations (36) and coil ends (51) axially arranged on either side of the stack of laminations of a rotor of a rotating electric machine, each supporting flange (55, 56) comprising: - a radial wall (59) provided with a main opening (60) enabling a shaft (35) of the rotor to pass therethrough; an annular collar (75) extending at the outer periphery of the radial wall (59) and extending axially towards the rotor, said annular collar (75) having one surface resting on the relevant outer radial end surface of the lamination stack (36); - at least one of the supporting flanges (55, 56) also comprising at least one axial ventilation blade (71) that is associated with a through-hole (72) in the radial wall (59), said axial ventilation blade (71) being intended for ensuring axial circulation of the air flow in the rotor. The rotor of the rotating machine comprises such an assembly of flanges.
