摘要： A rotor for an electric machine having a number of poles includes a shaft that extends along a portion of an axis and defines an outer surface. A first core portion extends along a portion of the axis to define a first core length. The first core portion includes a first reduced back portion that has an inside surface that does not contact the outer surface. A second core portion is coupled to the first core portion for rotation. In some constructions, a coupling member interconnects the shaft, the first core portion, and the second core portion such that the shaft, the first core portion, and the second core portion rotate about the axis substantially in unison.

摘要： A joint (10) for fiberglass pipes (12, 14) is provided wherein mating female and male threads are ground or scribed into the ends of the pipes (12, 14) to be joined. At least one of the ground, threaded surfaces has a paste thread (16) contact molded into it so that the root or base of the paste thread is below the crest of the ground thread. Upon mating of the coupled pipe ends, the paste thread surface (16) provides a smooth finish and a relatively low, consistent engagement and disengagement torque. The overlapped projections of the ground male and female threads provide for mechanical interlock and correspondingly enhanced tensile strength in the joint.

摘要： A cathodically protected water heater which eliminates the need of a conventional anode rod. The water heater tank includes a cylindrical shell (2) enclosed by upper and lower heads (3, 4), and a gas burner (6) is located beneath the lower head. The waste products of combustion are discharged upwardly through the tank via a flue (7) which is mounted within openings in the lower and upper heads. The outer surface of the flue as well as the upper surface of the lower head is coated with a metal anodic (12) to steel, and the metal coating on the flue extends continuously from the lower head to a location above the upper head. The inner surface of the shell and the upper head are coated with a corrosion resistant coating, such as glass or metal anodic to steel as well, and the upper edge of the flange (14) in the upper head bordering the opening is welded directly through the metal coating to the flue while the outer periphery of the lower head is welded to the lower edge of the shell. When a metal anodic to steel is coated onto the interior surface of the upper head and shell, it is applied in a sufficient thickness at least at the junction of the lower end of the peripheral flange of the upper head and the shell to bridge and seal the crevice opening which typically exists between the free end of the upper head flange and the shell wall. The metal coating over the upper head/shell crevice hydraulically seals the exterior weld between the upper head and shell from water contained in the heater and provides a corrosion barrier and anodic surface to contained water. Where welds are provided through the metal coating at the upper head/flue junction and shell/lower head junction, the metal coating flows about the weld and contacts the abutting corrosion resistant material to also hydraulically seal off those welds from contained water and provide a corrosion barrier and anodic surface to contained water. As the anodic metal coating is located centrally in the tank and extends the full height of the tank, more effective cathodic protection is achieved.
摘要翻译：一种阴极保护的热水器，不需要常规的阳极棒。热水器箱包括由上下头（3,4）包围的圆柱形壳体（2），并且气体燃烧器（6）位于下头部下方。燃烧的废物通过安装在下部和上部头部的开口内的烟道（7）向上排放通过罐。烟道的外表面和下头的上表面涂覆有金属阳极（12）到钢，烟道上的金属涂层从下头连续延伸到上头上方的位置。外壳和上头的内表面也涂有耐腐蚀涂层，例如玻璃或金属阳极氧化，并且与开口接壤的上端中的凸缘（14）的上边缘直接焊接金属涂层到烟道，而下头部的外周边焊接到壳体的下边缘。当对钢头进行金属阳极氧化涂覆到上部头部和外壳的内表面上时，至少在上部头部和外壳的外围法兰的下端的接合部处以足够的厚度施加桥接和密封通常存在于上头部凸缘的自由端和壳壁之间的缝隙开口。上头/外壳缝隙上的金属涂层将上部头部和外壳之间的外部焊缝与包含在加热器中的水液压密封，并为含水提供腐蚀屏障和阳极表面。在上部头部/烟道接合处和外壳/下部接头处通过金属涂层提供焊缝的情况下，金属涂层在焊缝周围流动并与邻接的耐腐蚀材料接触，同时将这些焊缝从含水中液压地密封并提供腐蚀屏障和阳极表面含水。由于阳极金属涂层位于罐的中央并延伸到罐的整个高度，因此实现了更有效的阴极保护。

摘要： A stator for a multi-phase electric machine having a plurality of core segments interconnected with one another and a plurality of coils. At least one core segment includes a plurality of teeth and a back portion that at least partially interconnects the teeth. The back portion of each segment has a first arrangement in which the teeth of that segment are a first distance from one another and a second arrangement in which the teeth of that segment are a second distance from one another, the second distance being smaller than the first distance. Each coil surrounds at least a portion of one tooth, wherein all coils surrounding teeth of a single core segment interconnect to at least partially define one phase winding.

摘要： A method of controlling a motor operating a pumping apparatus of a fluid-pumping application. The pumping apparatus (120) includes a pump (140) having an inlet (125) to receive a fluid and an outlet (130) to exhaust the fluid, and the motor (145) coupled to the pump to operate the pump. The method includes the acts of controlling the motor to operate the pump and monitoring the operation of the pump. The monitoring act includes monitoring a power of the motor, and determining whether the monitored power indicates an undesired flow of fluid through the pump. The method further includes the act of controlling the motor to cease operation of the pump when the determination indicates an undesired flow of fluid through the pump and zero or more other conditions exist.
