    • A rotor-stator structure for electrodynamic machinery is disclosed to, among other things, minimize magnetic flux path lengths and to eliminate back-iron for increasing torque and/or efficiency per unit size (or unit weight) and for reducing manufacturing costs. In one embodiment, an exemplary rotor-stator structure can comprise a shaft defining an axis of rotation, and a rotor on which at least two substantially conical magnets are mounted on the shaft. The magnets include conical magnetic surfaces facing each other and confronting air gaps. In some embodiments, substantially straight field pole members can be arranged coaxially and have flux interaction surfaces formed at both ends of those field poles. Those surfaces are located adjacent to the confronting conical magnetic surfaces to define functioning air gaps. Current in coils wound on the field poles provide selectable magnetic fields that interact with magnet flux in flux interaction regions to provide torque to the shaft.
    • 公开了用于电动机械的转子 - 定子结构,其特征在于最小化磁通路径长度,并消除用于增加每单位尺寸(或单位重量)的扭矩和/或效率以及降低制造成本的背铁。 在一个实施例中,示例性转子 - 定子结构可以包括限定旋转轴线的轴和在轴上安装有至少两个基本上圆锥形的磁体的转子。 磁体包括面对彼此并面对气隙的锥形磁性表面。 在一些实施例中,基本上直的场磁极构件可以同轴布置并且在这些场磁极的两端形成磁通相互作用表面。 这些表面位于与面对的锥形磁性表面相邻以限定功能性气隙。 缠绕在场磁极上的线圈中的电流提供可选择的磁场,其与磁通量相互作用区域中的磁通量相互作用以向轴提供扭矩。

    • Two longitudinally extending conveyors are connected by a plurality of novel hinge structures for movement between a first position with the two conveyors substantially in line, and a second position with one of the conveyors folded parallel to and on top of the other conveyor. One conveyor called a skate conveyor is referred to as the basic conveyor, while the other shorter conveyor is commonly called a stick conveyor and is herein referred to as the extension conveyor. Each hinge structure comprises a flat coupling hinge leaf generally triangular in shape and having acute apexes respectively one at each end. Each of the hinge structures includes a control link and pivotal connections respectively connected to the basic and extension conveyors, while a control link has a pivotal connection at one end with the hinge leaf near the obtuse apex at one end and is connected to the extension conveyor at its other end. This combination of conveyors is especially adaptable to dispatch a load between two locations which are at different levels.
    • 两个纵向延伸的输送机通过多个新颖的铰链结构连接,用于在第一位置与基本成行的两个输送机之间移动;以及第二位置,其中一个输送机平行于另一个输送机折叠。 称为溜冰输送机的一个输送机被称为基本输送机,而另一个较短的输送机通常称为输送机,在本文中称为延伸输送机。 每个铰链结构包括平面联接铰链叶片,其大致三角形形状,并且在每一端分别具有锐角顶点。 每个铰链结构包括分别连接到基本和延伸输送机的控制连杆和枢转连接,而控制连杆在一端具有与铰链叶片在一端处靠近钝角顶点的枢轴连接,并连接到延伸输送机 在另一端。 输送机的这种组合特别适用于在不同水平的两个位置之间调度负载。

    • A method, apparatus and system producing for electrodynamic machinery are disclosed. In one embodiment, an integrated stator-housing structure for constructing electrodynamic machines includes one or more field pole members. Each field pole member can have a first pole face and a second pole face. Also, the members each can have a field pole core being configured to produce a flux path in a direction from the first pole face to the second pole face. In one embodiment, the integrated stator-housing structure can also include a housing structure configured to support the one or more field pole members. The housing structure is configured to mate with one or more other housing structures to form an enclosure of an electrodynamic machine. In another embodiment, the housing structure is composed of potting compound formed with the one or more field pole members in, for example, a mold. In this case, the integrated stator-housing structure includes the potting compound and the field pole members. In a specific embodiment, the flux path is straight from the first pole face to the second pole face.
