Abstract
An example drilling turbine includes a turbine power section having a turbine shaft and a plurality of turbine stages axially arranged along the turbine shaft. A turbine bearing section is coupled to the turbine power section and has a drive shaft operatively coupled to the turbine shaft such that rotation of the turbine shaft rotates the drive shaft. The turbine bearing section includes a lower mandrel that houses a portion of the drive shaft rotatable with respect to the lower mandrel, one or more magnets disposed on an inner surface of the lower mandrel, a generator coil coupled to the drive shaft and aligned with the magnets, and one or more sensors coupled to the drive shaft and in electrical communication with the generator coil. The turbine shaft rotates the drive shaft, which rotates the generator coil with respect to the magnets, and thereby generates electrical power for the sensors.
