STATOR FORMATION METHOD FOR DOWNHOLE MOTORS Russian patent published in 2020 - IPC H02K15/02 F04C2/107 

Abstract RU 2723681 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Method of forming stator (18) comprises placing inner tubular element (62) having inner surface (22) inside outer tubular element (60). Both internal tubular element (62) and external tubular element (60) are made of metal or metal alloy. Then rigid mandrel (132) is installed inside inner tubular element (62) and compression force is applied to at least one of internal tubular element (62) and external tubular element (60). Compressing force causes connection of internal tubular element (62) with external tubular element (60).

EFFECT: technical result is improvement of stator formation method.
