Abstract (en)
[origin: WO2021240101A1] Rotor (10) comprising a shaft (12) mounted around an axis of rotation (X); - a laminated core (14) mounted coaxially on the shaft (12), the laminated core (14) extending between a front side face (143) and a rear side face (144). It comprises first internal cavities (141), a plurality of permanent magnets (15) housed inside the first internal cavities (141), a front flange (17) and a rear flange (19) in the form of discs and arranged on either side of the laminated core (14). The shaft (12) is provided with an internal inlet channel (124) for circulating a coolant. The front (17) or rear (19) flange is configured to form, with the front (143) or rear (144) side face, at least one front outlet channel (175) or rear outlet channel (195) inside which a coolant is circulated. The front (175) or rear (195) outlet channel connected to the inlet channel opens at an outlet opening (178) at the outer periphery (177) of the front flange (17) or rear flange (19).
