ABSTRACT:
A downhole motor to drill a wellbore including a pumping apparatus having a first chamber configured to receive a first fluid and a second fluid, and a first flexible diaphragm disposed with the first chamber configured to separate the first and second fluid, wherein the first flexible diaphragm is configured to transfer a hydraulic energy between the first fluid and the second fluid. In addition, the downhole motor includes a motor portion coupled to the pumping apparatus and configured to receive the second fluid and convert the hydraulic energy of the second fluid into a mechanical energy, thereby creating a torque. Further, the downhole motor includes a bit shaft coupled to the motor portion, configured to receive the torque from the motor portion and the first fluid from the pumping apparatus.
