ABSTRACT:
In large capacity and superconducting rotating electric machines, the stator coil windings are frequently placed in the air gap between the stator core and the rotor. This so-called air gap winding rotating electric machine has the drawback that reliably securing the stator coils to the stator core is difficult. In the air gap winding rotating electric machine according to the present invention, the stator coils are disposed between the outer circumference of a thin-walled electrically insulating cylinder surrounding the rotor and the inner circumference of the magnetic shield on the stator side. Taper keys are inserted between the outer circumference of the stator coils and the inner circumference of the magnetic shield so as to firmly press the stator coils against the thin-walled electrically insulating cylinder. In this manner, the stator coils can be easily and reliably secured to the stator.
