  • Publication number: 20240055923
    Abstract: An electric motor includes a plurality of structural rings that define a plurality of stator teeth. Tooth sections are formed from stacks of laminations that are positioned within each stator tooth of the plurality of stator teeth. The stacks of laminations are positioned between adjacent rings of the plurality of structural rings. Bobbins are positioned over each stator tooth. Winding sections are positioned over each stator tooth and around the bobbins, respectively. The winding sections are coupled together to define a plurality of stator poles that are configured to be selectively energized. An outer ring is positioned around an outer circumference of the plurality of stator teeth. The outer ring defines a stator core and contains the winding sections within a stator cavity defined between the outer ring and an inner circumference of the plurality of structural rings.

  • Publication number: 20230299634
    Abstract: A modular fluid pump includes a stator having a plurality of stator teeth and windings that are positioned on the stator teeth. A rotor has a central shaft and substantially hemispheric ends and a plurality of magnets that define an electromagnetic communication with the windings A housing surrounds the stator and includes a fixed end cap that receives one of the hemispheric ends of the central shaft and defines a rotational axis of the rotor. A securing end cap that receives the other hemispheric end of the central shaft. The central shaft and the fixed and securing end caps define the rotational axis of the rotor. Engagement of the hemispheric end 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.

  • Patent number: 9587639
    Abstract: The present pump devices provide a dual pump using two (or more) electric motors (e.g. brushless DC motors) driving the pumps independently, including integration of hydraulic and electrical components and connectors. The illustrated arrangements include an in-line single shaft version, a parallel side-by-side separate shaft version, and an inside-outside version. Each configuration includes a housing supporting formation of: shared structural support for the pumps and motors (e.g., bearings, stator, relationship of components), fluid pump and hydraulic system (e.g., fluid passageways, ports connectors) and motor electrical control (e.g., control circuitry and sensory components).
