Zusammenfassung:A downhole motor assembly which has a housing, a power section with a stator and a rotor contained within the housing. A proximal drive assembly is connected with a proximal rotor end, a distal drive assembly is connected with a distal rotor end, and a proximal thrust bearing is arranged between the housing of the proximal drive assembly. A distal thrust bearing is arranged between the housing and the distal drive assembly. An axial load decoupling device is in the distal drive assembly located longitudinally between the distal rotor end and the distal thrust bearing, and is used for separating axial loads imposed on the proximal thrust bearing from axial loads imposed on the distal thrust bearing.
