INTEGRATED PUMP ASSEMBLY WITH ONE MOVING PART WITH STACKED STATOR

A pump assembly can pump fluid with a single moving part. The pump includes a casing with an inlet and an outlet. The pump includes an impeller to rotate inside the casing to create low pressure at the inlet and increase pressure to expel fluid from the output. The impeller is physically connected to a rotor within the pump casing. The rotor includes permanent magnets arranged radially around a surface of the rotor opposite the physical connection to the impeller. A variation replaces the magnets with a switched reluctance path. The pump includes a stator assembly within the casing, magnetically coupled to the rotor, the stator assembly having electrically controllable conductors to drive the rotor with axial flux. The stator assembly includes stacks of multiple layers of coated conductor having multiple spokes as the stator core.
