The electric motor () comprises: —a shaft () mounted so as to be able to rotate about an axis (X); —a rotor () and a stator () received in a housing (). The shaft () is engaged in an aperture in the front wall () and an aperture in the rear wall () of the housing (), with a front bearing () and a rear bearing () being interposed respectively. It comprises an inner channel () for a cooling fluid circulation and at least one hole () in communication with the inner channel and leading into a front inner space () or rear inner space () of the housing (). A deflector () that is fixed in relation to the shaft comprises a deflecting wall () that diverts the flow of cooling fluid entering the inner space from the hole towards the corresponding bearing.

Electric motor comprising a cooling fluid deflector

A rotor including a shaft mounted around an axis of rotation; —a laminated core mounted coaxially on the shaft, the laminated core extending between a front side face and a rear side face. It includes first internal cavities, a plurality of permanent magnets housed inside the first internal cavities, a front flange in the form of discs and arranged on either side of the laminated core. The shaft is provided with an internal inlet channel for circulating a coolant. The front or rear flange is configured to form, with the front or rear side face, at least one front outlet channel or rear outlet channel inside which a coolant is circulated. The front or rear outlet channel connected to the inlet channel opens at an outlet opening at the outer periphery of the front flange or rear flange.
