Abstract (en)
[origin: WO2017001377A1] The present invention relates to an electric machine comprising a rotor (10) and a stator (12), said rotor being formed of a rotor body (18) with a stack of laminations (16) and placed on a rotor shaft (14), said laminations comprising housings (40) to house magnetic flux generators (20) and polar expansions (42) situated between the outer (36) and inner (38) edges of said laminations. According to the invention, the polar expansions (42) are connected by a connecting bridge (48) to the inner edge (38) of said laminations.
