Abstract[English]
The invention relates to a rotor for an electric machine, the rotor having a rotor body (1) and pairs of magnetic poles, each magnetic pole being composed of at least two flux barriers - an internal flux barrier comprising two inclined recesses (6) arranged on either side of a central recess (5), - an external flux barrier comprising two inclined recesses (7) arranged between the central recess (5) of the internal flux barrier and the outer edge of the body (1) of the rotor, and a permanent magnet positioned in at least one recess (5, 6, 7) of each of the two flux barriers, and two additional recesses (20) arranged between the recesses (7) of the external flux barrier and the outer edge of the body (1) of the rotor in order to modify the trajectory of the magnetic fluxes emitted by the magnets.[French]
L'invention concerne un rotor pour machine électrique avec un corps de rotor (1) et des paires de pôles magnétiques, chaque pôle magnétique étant composé d'au moins deux barrières de flux - une barrière de flux interne comprenant deux évidements inclinés (6) et disposés de part et d'autre d'un évidement central (5), - une barrière de flux externe comprenant deux évidements inclinés (7) disposés entre l'évidement central (5) de la barrière de flux interne et le bord externe du corps (1) du rotor, et un aimant permanent positionné dans au moins un évidement (5,6,7) de chacune desdites deux barrières de flux, et deux évidements supplémentaires (20) disposés entre les évidements (7) de la barrière de flux externe et le bord externe du corps (1) du rotor pour modifier la trajectoire des flux magnétiques émis par lesdits aimants.
