Abstract: A vibration-cancelling module includes a first rotor having a first eccentric body, a second rotor having a second eccentric body, and a stator assembly in electromagnetic communication with the first and second rotors. A central shaft extends between the first and second rotors. The first and second rotors rotationally operate about a common rotational axis with respect to one another between a balanced position and a plurality of eccentric positions. A controller has an accelerometer assembly and a rotor-position sensor assembly. The controller delivers an electrical current to the stator assembly at least based upon the accelerometer assembly. A common housing contains the first and second rotors, the stator assembly, the central shaft and the controller.

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.

Abstract: A bi-polar hybrid stepper motor includes a stator having a primary winding. The stator and the primary winding are positioned within a housing. A rotor has a magnetic component. The rotor is rotationally operable relative to the stator. An axial coil assembly is positioned within the housing and located proximate ends of the rotor and having a secondary winding. At least a portion of the magnetic component of the rotor is produced by the axial coil assembly in an energized state. The energized state produces an electromagnetic communication between the rotor and the stator.

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).

Abstract: A vehicle including a frame member and a vehicle wheel mounted for rotation relative to the frame member about a rotation axis. The vehicle also includes a transmitting circuit mounted on a one of the frame member and the vehicle wheel. The transmitting circuit includes an antenna coil having a diameter. A ferrite core is mounted adjacent the transmitting circuit on the one of the frame member and the vehicle wheel. A non-planar, curved antenna coil is mounted on the other of the frame member and the vehicle wheel. The non-planar, curved antenna coil has a radius of curvature that is approximately equivalent to the rotational pathway of the transmitting circuit.
