Patent ID: 8376720

Claim:
A gerotor pump, comprising: an inner ring rotateable about an axis, wherein the inner ring has an outer diameter contact surface; an outer ring having an inner diameter contact surface that defines a central opening within the outer ring, wherein the central opening receives the inner ring, and wherein a portion of the inner diameter contact surface engages a portion of the outer diameter contact surface of the inner ring; and a three phase induction motor including a rotor and a stator that surrounds the rotor, wherein the rotor surrounds the outer ring and exerts a driving force on the outer ring such that the outer ring rotates about the inner ring and the inner ring rotates about the axis, wherein the rotor and the outer ring are a single component, and wherein the inner diameter contact surface of the outer ring and the outer diameter contact surface of the inner ring creates a plurality of chambers, wherein rotation of the inner ring and the outer ring expand and contract the chambers to generate a pumping action that increases pressure of fluid located within the chambers, and wherein fluid is expelled from the gerotor pump as the chambers contract in size.
