Assemblies for an Internal Gear Pump With Hydrostatic Support Features

An assembly comprising:

• an assembly housing having an internal chamber therein;
• an electric motor disposed in the internal chamber of the assembly housing and comprising (i) a stator that is fixedly positioned in the internal chamber of the assembly housing, and (ii) a rotor positioned within the stator and rotatable relative to the stator;
• and
• a gear pump positioned in the assembly housing, at least partially within the rotor of the electric motor, wherein the gear pump comprises:
• a drive flange coupled to the rotor of the electric motor such that the rotor is configured to rotate the drive flange,
• a ring gear coupled to the drive flange and configured to rotate therewith,
• a pump pinion disposed within the ring gear, such that external teeth of the pump pinion engage with internal teeth of the ring gear, and
• a plurality of ports comprising:
• a first port and a second port, wherein as the rotor rotates, the drive flange and the ring gear rotate therewith, causing the pump pinion to rotate within the ring gear, such that fluid is drawn from the first port and displaced to the second port for discharge.
