Abstract (en)
[origin: WO2013060960A2] The rotor (1) according to the invention comprises a plurality of alternating north poles (N) and south poles (S) formed from a plurality of permanent magnets (3) having a radial polygonal section and arranged in first recesses (4). These first recesses extend axially and are distributed regularly between a circumferential portion (5) and a central portion (6) of the magnetic mass (2) of the rotor in such a way as to define a plurality of circumferential polar sections (10). In accordance with the invention, the radial section comprises a substantially rectangular portion (8) next to the circumferential portion adjacent to a substantially trapezoidal portion (7) next to the central portion. According to another feature of the rotor, a ratio (R) of a first height (h) of the trapezoidal portion to a second height (H) of the rectangular portion, in a radial direction, is predetermined in such a way as to maximise the efficiency of the electrical machine.
