Modular fluid pump for use in diverse applications

A modular fluid pump comprising:

• a stator having a plurality of stator teeth and windings that are positioned on the plurality of stator teeth;
• a rotor having a central shaft and substantially hemispheric ends and a plurality of magnets that define an electromagnetic communication with the windings;
• a housing surrounding the stator and including a fixed end cap that receives one of the hemispheric ends of the central shaft and defines a rotational axis of the rotor;
• and
• a securing end cap that receives the other hemispheric end of the central shaft, wherein the central shaft and the fixed and securing end caps define the rotational axis of the rotor, wherein engagement of the hemispheric ends with the central shaft and the fixed and securing end caps maintains the rotor and the central shaft aligned with the rotational axis and balanced within the stator, wherein the fixed end cap is attached to the stator and includes structural posts that support a position of a printed circuit board relative to the housing.
