Abstract
A progressive cavity positive displacement motor having a rotor and stator includes a measurements-while-drilling (“MWD”) tool disposed within the rotor. The motor may use one or more alignment members to measure the position of the rotor relative to the stator. The MWD tool can collect data regarding physical properties such as orientation, temperature, pressure, and other properties. The MWD tool incorporated in the rotor is configured to measure differential properties near or at the uphole and downhole ends of the motor.
