  • Apparatus and method for controlling or limiting rotor orbit in moving cavity motors and pumps
    Patent number: 10612542
    Abstract: Techniques involve a motor assembly including a rotor and a stator. The stator includes a contact surface for contacting an outer surface of the rotor. The contact surface includes a rigid material. The motor assembly also includes at least one constraint disposed along a length of the motor assembly, where the constraint constrains a radial and/or tangential movement of the rotor relative to the stator. The at least one constraint may be disposed at one or more proximate ends of the motor assembly, and/or along the length of the motor assembly. The contact surface of the stator may have a profile including peaks and valleys, and in some embodiments, the contact surface may be treated to reduce friction and/or wear.

  • Positive displacement motor with radially constrained rotor catch
    Patent number: 9982485
    Abstract: Techniques relate to a moving cavity motor or pump, such as a mud motor, including a rotor, a stator, and one or more apparatus for constraining (i.e., controlling or limiting) the movement of the rotor relative to the stator, where the apparatus for constraining is operable with the rotor catch. The motor may include a top sub, power section having a progressive cavity motor with a stator and rotor, a rotor catch, and an apparatus between a proximal and distal end of the rotor catch shaft. The apparatus may constrain the radial and/or tangential movement of the rotor catch shaft and the rotor.
