Abstract
A pump, comprising a rotor axially located between a fluid inlet section and a fluid outlet section, wherein the rotor is configured to rotate about a center axis, a stator surrounding the rotor, wherein the stator includes an inner diameter surface and an outer diameter surface, wherein the inner diameter surface includes a groove surrounding the stator and concentric about the center axis, and a ring surrounding the stator, wherein the ring is adjacent to the groove and defines a gap between an outer diameter of the surface and an inner surface of the ring, wherein the ring includes a ring mass and the stator includes a stator mass, and the ring mass is substantially equal to the stator mass.

A pump, comprising:
- a rotor axially between a fluid inlet section of the pump and a fluid outlet section of the pump, wherein the rotor is configured to rotate about a center axis;
- a stator surrounding the rotor;
- and
- a ring surrounding about the stator, wherein the ring has a ring mass and the stator has a stator mass, and the ring mass is substantially equal to the stator mass, wherein the ring is configured to rotate about the stator in response to a magnetic flux introduced into the stator.
A pump, comprising:
- a rotor axially between a fluid inlet section of the pump and a fluid outlet section of the pump, wherein the rotor is configured to rotate about a center axis;
- a stator surrounding the rotor, wherein the stator includes an inner diameter surface and an outer diameter surface, wherein the inner diameter surface includes a groove encompassing the stator and concentric about the center axis;
- and
- a ring surrounding about the stator, wherein the ring is located adjacent to the groove and defines a gap between an outer diameter of the surface and an inner surface of the ring, wherein the ring has a ring polarity opposite of a stator polarity.
A pump, comprising:
- a rotor axially located between a fluid inlet section of the pump and a fluid outlet section of the pump, wherein the rotor is configured to rotate about a center axis;
- a stator surrounding the rotor and including a stator mass, wherein the stator includes an outer diameter surface that includes a groove encompassing the stator and concentric about the center axis;
- and
- a ring surrounding about the stator, wherein the ring is adjacent to the groove and defines a gap between the outer diameter surface and an inner diameter surface of the ring, wherein the ring includes a ring mass substantially equal to the stator mass.
