ELECTRIC OR HYBRID MOTOR VEHICLE HAVING AN ELECTRIC MOTOR HAVING A ROTOR INCLUDING AT LEAST ONE MAGNETIC LAYER INCLUDING GROOVES

Abstract

The invention relates to an electric or hybrid motor vehicle comprising an electric motor and a cooling circuit, said motor having a rotor (1) having an axis of revolution (A), said rotor (1) comprising a plurality of magnetic layers (2) arranged axially about the axis of revolution (A), the rotor (1) having at least one axial channel (3) configured for circulating a cooling fluid, said axial channel (3) being substantially parallel to the axis of revolution (A), characterized in that at least one of the magnetic layers (2) has a plurality of grooves (4), each groove (4) extending radially about the axis of revolution (A) from said axial channel (3) outwards from the rotor (1), each groove (4) being configured to guide said cooling fluid outwards from the axial channel (3).
