Abstract (en)
[origin: WO2012113416A2] A module (10) for a rotor of an electric machine, said rotor being excited by means of permanent magnets (200) and rotating in a fluid medium, wherein the module (10) contains a cylindrical, active part which has a plurality of circular soft-magnetic laminations (100) combined to form a laminate stack (20) and having a central opening (110) for receiving a rotor shaft (30); wherein at least two permanent magnets (200), protected from the liquid medium, are arranged in at least two corresponding cutouts (120) in the laminate stack (20), and wherein the cutouts (120) are formed beneath a cylindrical circumferential surface of the laminate stack (20).
