Abstract

The invention relates to a rotor for an electric motor (100; 800; 1000; 1500), comprising a main member (104; 200; 402; 502; 600; 802; 1300) that contains fiber composite and has at least one receptacle (302; 406) for accommodating magnets (312, 314). According to the invention, at least two magnets (312, 314) are arranged in at least one receptacle (302; 406) of the main member (104; 200; 402; 502; 600; 802; 1300) of the rotor. The invention further relates to a method for producing said rotor and the use thereof.
