  "id": "MLC-T-OAG-002878",
  "term": "Positive displacement motor",
  "field": "Oil and gas",
  "definition": "A downhole motor that converts the hydraulic energy of drilling fluid into mechanical energy to rotate the drill bit without rotating the entire drill string. The fluid flows through a helical rotor and stator assembly, causing the rotor to turn. This motor is commonly used in directional drilling operations to steer the wellbore along a planned trajectory.",
