  • Patent number: 11108291
    Abstract: The invention relates to a flange (1) for an electrical machine (100), said flange being configured to at least partially cover winding overhangs (10) that form part of the electrical machine (100), the flange (1) comprising a chamber (5) able to receive a cooling fluid, characterized in that the flange (1) comprises at least one first orifice and at least one second orifice allowing cooling fluid to enter the chamber (5) or allowing cooling fluid to leave the chamber (5), said chamber (5) having a profile that compliments that of at least one winding overhang (10). Said invention is applicable to motor vehicles.

  • Patent number: 10530206
    Abstract: The present invention concerns a brushless electric machine with a rotor having interior permanent magnets, characterised in that the rotor consists of a tubular core (1), said core (1) having N pairs of longitudinal slots (2, 3) having trapezoidal cross-section, a width La and a length L, where La/L is between 0.25 and 0.35, the two slots (2, 3) of a pair extending on either side of the median radial plane, at an angle of 7.5°±1.5°, the core having, in the region of convergence of each pair of slots, a longitudinal channel (10) opening on either side of the front ends of the core (1).
