Abstract (en)
[origin: WO2018154218A1] The invention mainly relates to a rotor (12) of an electrical machine characterised in that: - each tooth (35) comprises at least two connecting arms (42) to the hub (32); - each arm (42) comprises a covering part with a permanent magnet (39) corresponding to a part of the arm (42) facing the permanent magnet (39) and in that this covering part has a radial length (Hu) and an orthoradial thickness (e); and - a ratio between the radial length (Hu) and the orthoradial thickness (e) is between 1.8 Tesla divided by the value of the remnant induction of the corresponding permanent magnet (39) and 2.16 Tesla divided by the value of the remnant induction of the corresponding permanent magnet (39).
