  • Publication number: 20240120809
    Abstract: A fluid pump includes a motor disposed within an outer housing. The motor includes a stator and a rotor in electromagnetic communication with the stator. Windings are disposed on the stator that receive an electric current for defining the electromagnetic communication. A pump element is attached to the rotor via a drive shaft. The pump element operates with the rotor to deliver a fluid through a hydraulic fluid path. A plurality of sensors measure information related to at least one of the stator, the windings, the rotor, the pump element, the fluid and the hydraulic fluid path. A controller is in communication with the windings for delivering the electric current to the windings. The controller is also in communication with the plurality of sensors for measuring and recording the information and communicating this information to one of an external memory and an external controller.

  • 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: 10578005
    Abstract: An apparatus includes two pumps and a circuit-changing valve connected to two cooling circuits, with the valve being controlled by a pressure differential created by the pumps. This simplifies controls, reduces components of the pumping system, and also provides a backup pump for each system. The valve's spool is controlled so that when the first pump is started before the second pump (or it generates a higher fluid pressure), the valve causes the two pumps to be connected in a serial arrangement with fluid being pumped through the first circuit and then through the second circuit. But when the second pump is started before the first pump, the valve causes the two pumps to be connected in a parallel arrangement so that the first pump moves fluid only through the first circuit, and the second pump moves fluid only through the second circuit. The valve includes an anti-dithering device.

  • Patent number: 10267417
    Abstract: A transmission shifter includes a base, a shift lever movable between gear positions, and a pawl, a pawl blocker, a permanent magnet, an electro-magnet, and an electrical circuit for selectively activating the electro-magnet when a predetermined vehicle condition is sensed. The permanent magnet's attraction to an iron based surface of the electro-magnet normally holds the blocker in a pawl-blocking position, keeping the shift lever in park position, until the electrical circuit activates the electro-magnet and the pawl is depressed. When activated, the electro-magnet biases the blocker toward a pawl-unblocked position. A ramp lever keeps the pawl blocker in the park position until the pawl mechanically moves the ramp lever and magnetically-biased blocker together, thus allowing the shift lever to be moved from park position. The park lock system is characterized by an absence of movement in response to an electrical signal to an electro-mechanical device and thus operates noise-free.

  • Patent number: 10088040
    Abstract: A park lock system for a shifter of an automatic transmission, according to one embodiment, includes a blocking member pivotal between a locked position to prevent movement of the shifter and an unlocked position for allowing movement of the shifter. At least a portion of the blocking member may include hard magnetic properties, such as having a permanent magnet coupled therewith. An electromagnet may have a core member proximate the magnetic portion of the blocking member to cause the blocking member to move to or remain in the locked position when the electromagnet is de-energized. Accordingly, when the electromagnet is energized, the electromagnet may be configured to generate a magnetic field in repelling polarity to the magnetic portion that causes the blocking member to move to the unlocked position.

  • Patent number: 9831580
    Abstract: An apparatus electrically connects a motor's on-board stator circuit board to multiple circuits on a controller circuit board using an edge connector on the controller circuit board that engages opposing pads on an edge of the stator circuit board. The edge connector includes tuning-fork-like conductors each with pairs of protruding arms positioned to both engage the pads for electrical contact and also frictionally engage the pads for mechanical retention. A related method of assembly uses the edge-connect system for quick, reliable and sure assembly even under blind assembly conditions.

  • 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).
