  • Publication number: 20120200177
    Abstract: Disclosed is a stator device adapted to be arranged in an electrical machine, where the electrical machine further comprises a moving device, where the stator device is a multi-phase stator device, where the phases are arranged side-by-side in a direction perpendicular to direction of motion of the moving device, and where each phase comprises a first stator core section having a set of teeth, a second stator core section having a set of teeth, and a coil, and where the teeth are arranged to protrude towards the moving device; and wherein at least two neighbouring phases share a stator core section, so that the first stator core section of a first phase and a second stator core section of a second phase is formed as a single unit.

  • Publication number: 20110025140
    Abstract: A permanent magnet machine is provided comprising a stator and a rotor, the rotor being adapted to rotate relative to the stator, the rotor comprising a plurality of permanent magnets separated in the circumferential direction from each other by axially extending rotor pole pieces for concentrating the magnetic flux from the permanent magnets, the stator having a structure that defines axial limits of an air gap between the stator and the rotor for communicating magnetic flux between the stator and the rotor, wherein that at least some of the permanent magnets extend axially outside the axial limits of the air gap as defined by the stator structure.

  • Publication number: 20080053638
    Abstract: In certain exemplary embodiments of the present invention, three-dimensional micro-mechanical devices and/or micro-structures can be made using a production casting process. As part of this process, an intermediate mold can be made from or derived from a precision stack lamination and used to fabricate the devices and/or structures. Further, the micro-devices and/or micro-structures can be fabricated on planar or nonplanar surfaces through use of a series of production casting processes and intermediate molds. The use of precision stack lamination can allow the fabrication of high aspect ratio structures. Moreover, via certain molding and/or casting materials, molds having cavities with protruding undercuts also can be fabricated. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.

  • Publication number: 20050229566
    Abstract: Curved shapes applicable for making lawnmower cleaning tools for removing debris in a cutting chamber of a lawnmower have been developed. Using these conformally shaped curves improves the performance of mechanically based lawnmower cleaning tools dramatically. The conformal shapes closely conform to the shape of structures found in the cutting chamber of lawnmowers. The shape is designed such that in use, curved portions of tools based on them usually pass within about ¼ inch of the surfaces being cleaned even if the curves touch the cutting chamber surfaces at only one point. Straight portions can be adjacent the curved portions of the curves for cleaning the vertical portions such as a mower skirt around the cutting chamber. The curves can also comprise smaller features designed for cleaning hard to reach areas of the lawnmower cutting chamber.
