A moving or progressive cavity motor or pump is disclosed, the motor including a rotor and a stator, the stator having one or more inserts or gearing sections to limit a lateral movement of the rotor relative to the stator. In some embodiments, the motor or pump may include a rotor and a stator, the stator including: a first, helicoidal, section comprising a compliant material having a first compressibility; a second section, helicoidal, non-helicoidal, or combination thereof, having a second compressibility, wherein the second compressibility is less than the first compressibility.

A system transmits a wireless power transmission from a bottom hole assembly of a drill string. The system has a downhole component having a wireless power transmitter adapted to wirelessly transmit at least one wireless power transmission and a wireless power receiver adapted to receive the at least one wireless power transmission.

The rotor of a downhole motor includes a mandrel having at least one radial lobe, and an elastomeric tubular sleeve compressed about the mandrel so as to establish frictional engagement therebetween. The sleeve is compressed about the mandrel through one of various processes, including heat shrinking, vacuum shrinking, and stretching.
