Abstract (en)

[origin: EP1296438A2] When molding reinforced fiber layers (12) of a creepage block (11) which is in contact with a field winding 84) in a rotor (1) of a rotary electric machine, a layer containing organic fibers (13; 14,15; 16) made from polybenzoimidazole, polyparaphenylenebenzobisoxazole, aromatic polyamide, polyarylate, and aromatic polyester is integrally molded on that side of the creepage block (11) which is for contact with a field winding (4). The rotor (1) thus formed stabilizes a slippage between the field winding (4) and the creepage block (11) caused by thermal expansion of the field winding in the rotor (1) during the operation and thereby minimizes the amount of bending of a rotor shaft. <IMAGE>
