Abstract: An axial flux switched reluctance motor and/or generator, and controls are provided. It includes a stator, which includes a front surface and a rear surface, and sidewalls that extend from the front surface to the rear surface. The stator includes salient stator poles positioned on the front surface. Each one of the salient stator poles including: a bobbin protruding out from the front surface in a direction along an axis of the bobbin that is perpendicular to the front surface; the bobbin comprising a bobbin front surface that is substantially parallel to the front surface of the stator; and a coil of electrically insulated wire wound around the bobbin. A rotor includes a front rotor surface and an opposite facing rear rotor surface; and further includes a plurality of rotor poles. The rotor is affixed to a shaft and rotates about an axis of rotation that is aligned with the shaft.

Abstract: A state machine includes a stator assembly arranged to generate a rotating electromagnetic field in response to a control signal and a rotor assembly, positioned adjacent to the stator assembly, arranged to rotate in response to the rotating electromagnetic field. A sensor is arranged to detect an angular position of the rotor assembly and output sensor data based on the angular position of the rotor assembly. A controller is arranged to receive the sensor data and adjust the control signal based on the angular position of the rotor assembly to adjust a torque of associated with the rotor assembly when the state machine functions as a motor or to adjust a power output from the stator assembly when the state machine functions as a generator.

Abstract: 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.

Abstract: A pump assembly can pump fluid with a single moving part, where the single moving part is free floating, inline within a sealed fluid path. The pump includes a stator core having a cylindrical shape with an opening through it. The stator includes electromagnetic coils arranged around a lateral surface of the stator core extending away from the center of the stator core. The pump assembly includes an impeller to spin within the cylindrical opening of the stator in response to selective charging of the electromagnetic coils. The impeller includes a cylindrical body having blades that align with the electromagnetic coils to create a magnetic flux path between selected coils through the impeller in response to selective charging of the electromagnetic coils.
