Abstract

The invention relates to an electric machine rotor (10) comprising a one-piece cylindrical body (12) having a longitudinal axis (C) and made of a first magnetic material (M1), having a radially external surface (14) and comprising several slots (16) distributed around the longitudinal axis (C), each extending along the longitudinal axis (C) and opening onto the radially external surface (14) of the cylindrical body (12), characterized in that the slots are filled by a second material (M2), said second material (M2) having a minimum conductivity of 10 Sm-1. The invention also relates to a method for manufacturing such an electric machine rotor. Figure 1
