METHOD OF MOLDING OF ACTIVE CORE OF WINDING BELT OF SMOOTH ARMATURE AND DEVICE FOR METHOD IMPLEMENTATION Russian patent published in 2008 - IPC H02K15/04 H02K15/12 

FIELD: electric engineering; electric machine industry.

SUBSTANCE: prior to execution of main operations of molding active core of smooth armature winding belt, which include impregnation, drying and baking of active core, according to invention, this active core is preliminarily subject to general radial compression and heating with delay and cooling in compressed condition, at that after compression device is dismantled from cold armature, standard binding is installed onto active core of winding belt and completing main operations of molding are performed. Demountable compression device for implementation of suggested method of molding active core of smooth armature winding belt consists of temporary wire technological binding made of untinned wire that is wound with tension onto winding belt along magnetic conductor length by uninterrupted continuous winding with even number of layers, and also demountable winding unit that is installed on armature mechanical structure. Result is achieved by provision of required radial specific pressure on surface of contact of winding belt casing insulation with magnetic conductor in finished armature.

EFFECT: increase of reliability of smooth armature of electric machine in the process of its long-term operation.
