    Abstract: In a unipolar transverse flux machine, to achieve a modular construction, which is favorable from a production standpoint, the stator (11) and the rotor (12) have an equal number of identical stator modules (14) and rotor modules (15); the rotor modules (15) are firmly seated, in alignment with one another, on the rotor shaft (13), and the stator modules (14) are rotated by a rotational angle from one another in the housing (10). When there are two stator modules (14), the rotational angle is 90° electrically, and when there are m stator modules (14), the rotational angle is 360°/m electrically, where m is an integer and is greater than 2. Each stator module (14) has an annular coil (23), disposed coaxially to the rotor axis (19), and U-shaped stator yokes (24) that fit over the annular coil, along with short-circuit elements (25) disposed between the stator yokes. Each rotor module (15) comprises two rotor rings (16, 17) with teeth on the outside, and between them a permanent-magnet ring (18), magnetized unipolarly in the direction of the rotor axis (19).

    Abstract: Disclosed is a transverse flux linear motor with permanent magnet excitation, which has a simple configuration as compared to systems using hydraulic or pneumatic pressure, or a rotary motor and a power transmission device, while being capable of generating high force, thereby achieving a high efficiency, as compared to conventional linear motors. The transverse flux linear motor includes a stator including stator cores and windings respectively wound around the stator cores and supplied with current, and a mover arranged at a central portion of the stator, the mover including mover cores and permanent magnets. Each of the permanent magnets is arranged between adjacent ones of the mover cores. Each stator core has a pair of column portions spaced apart from each other by a desired distance. The windings are arranged in pairs such that each of the winding pairs has two windings wound around respective column portions of an associated one of the stator cores. The two-phase transverse flux linear motor with permanent magnet excitation has two of a single phase motor units, that is, an A-phase motor unit and a B-phase motor unit, are arranged to face each other. A non-magnetic element for phase isolation is centrally arranged to prevent each of the A and B-phase motor units from being influenced by the magnetic circuit of the other. The stators of the A and B-phase motor units are arranged such that they are shifted from each other by nullnull nullpnull, in order to reduce pulsations of thrust forces generated in the motor.

    Abstract: A high speed non-contact beam scanning device sized and shaped to provide the ergonomic benefits of a pen or wand, yet can scan a wide angle moving beam across an information-bearing target in one or two dimensional scan patterns such as lines, rasters or other patterns in order to read information therefrom. The device is well suited for reading one or two dimensional bar-code or other printed matter. In order to achieve the high density optical packaging necessary for its high performance to size benefits the device employs a novel in-line or “axial” gyrating, or “axial” scan element. The axial scan element can accept an input light beam at one end and cause it to emerge from its opposite end as a scanned beam, propagating in the same general forward direction it had upon entering the element. Reflected light, which carries information contained on the target, is collected by an internal non-imaging light collector and is processed by signal processing electronics. All components are integrated into a thin low mass module small enough to fit in a pen. Communication from the device is achievable by a cable or by wireless means.

    Abstract: An in-hub brushless permanent magnet DC motor has a radial working gap but uses coils wound in the axial direction of the motor. The coils generate fields that interact with the permanent magnet fields across the radial gap. The stator includes a plurality of angularly spaced stator teeth that have faces radially spaced across the gap from the permanent magnet. The stator teeth are connected to the base and extend axially into a cavity within the hub. The permanent magnet is a magnetically-segmented ring magnet located on an outer rim of the hub radially outwardly from the stator teeth. The magnetic flux from the permanent magnet is directed radially across the gap and into the stator teeth. Each stator tooth has an axially oriented post around which is wound a coil that generates an axial field. The axially-oriented part of each coil forms part of the magnetic circuit. The magnetic flux directed radially into each stator tooth is turned axially into the post and through the coil. The axially directed magnetic flux through the coil and post on each stator tooth is redirected from the axial direction to the circumferential direction by a ring magnetic flux guide. The ring flux guide interconnects the stator teeth and forms part of the magnetic circuit. Because the coils are wrapped around axial posts instead of the stator teeth a larger coil volume is obtained which results in higher motor efficiency and reduced heating of the bearing system. The angular spacing between adjacent teeth can be made very small or even eliminated since there is no need to locate a winding device between them as is required in conventional radial-gap motors. This results in a reduction in the motor cogging torque, which in turn allows a higher tooth/pole symmetry leading to better force balance and lower acoustic noise.
