Patent number: 11319753Abstract: A stator for a downhole motor configured for use in a downhole environment. includes an inner tubular member formed from a first metallic material having an outer surface and a helically lobed inner surface, and an outer tubular member comprising a second metallic material that is different from the first metallic material. The inner tubular member is connected to the outer tubular member by compressive force passing from the outer tubular member through the inner tubular member to a rigid mandrel removably disposed within the inner tubular member. The inner tubular member and the outer tubular member form the stator of the downhole motor.Type: GrantFiled: January 6, 2021Date of Patent: May 3, 2022Assignee: BAKER HUGHES, A GE COMPANY, LLCInventors: Witali Huber, Gunnar Michaelis, Carsten Hohl, Erik Bartscherer, Harald Grimmer, Christian Fulda, Dorothea Marion Fischer, Thorsten Regener
