Abstract (en)

[origin: WO2010040536A1] The invention relates to a method for producing a fiber composite rotor (104; 500; 700; 904; 1004; 1508, 1510, 1512) comprising a main member (104; 200; 402; 502; 600; 802; 1300) for an electric motor (100; 800; 1000; 1500). Said method includes the following steps: fibers of a fiber material are combined with a matrix to obtain a fiber mixture (1322); the fiber mixture comprising diffusely arranged fibers is introduced into a female mold (1304, 1316, 1324) corresponding to the shape of the main member of the rotor; the fiber mixture (1308, 1318, 1326) is cured to obtain a main member (200; 402; 502; 600; 802; 1300) of the rotor, the fiber mixture being heated by a microwave source. The invention also relates to a female mold for producing the rotor as well as a use of the rotor in an electric motor.
