ABSTRACT:
A stator for a dynamoelectric machine preferably comprises a stack of modular sections, each modular section comprising an outer metallic cylinder formed from a plurality of metallic laminations arranged in a plurality of layers. Furthermore, the stator module comprises an inner nonmetallic cylinder formed from nonmetallic laminations having inwardly projecting teeth so as to define a plurality of slots along the inner circumference of the modular sections, the nonmetallic laminations being adhesively bonded to the outer metallic laminations. The stator modules of the present invention may be incorporated either in a conventional air-gap winding generator or employed in a superconducting rotor generator exhibiting high magnetic flux in the air-gap region between the rotor and the stator.
