    摘要： An alternator comprising an inner housing, an outer housing mounted over the inner housing and a plurality of o-rings positioned between the inner housing and the outer housing thereby creating a sealed flow chamber having a first plenum, an axial jacket, a second plenum, a first passageway interconnecting the first plenum and the axial jacket, a second passageway interconnecting the axial jacket and the second plenum, an inlet extending from the first plenum, and an outlet extending from the second plenum. The first and second plenums are disk shaped cavities extending diametrically across the alternator, and the axial jacket is an annular jacket extending around the alternator. The first passageway is located diametrically across from the inlet and the second passageway is located diametrically across from the first passageway. The outlet is located diametrically across from the second passageway.

    摘要： An alternator includes an inner housing and an outer housing. A pair of o-rings positioned therebetween create a sealed flow chamber having a first flow channel, a second flow channel and an axial passageway. The first flow channel is a disk shaped cavity extending diametrically across the alternator. The second flow channel forms an annular jacket extending entirely around the alternator. The axial passageway directs coolant axially from the first flow channel into the second flow channel. An inlet positioned diametrically across from the axial passageway allows coolant to enter the first flow channel, such that coolant entering the inlet must flow diametrically across the alternator to reach the axial passageway. An outlet positioned diametrically across from the axial passageway allows coolant to exit the flow chamber, such that coolant entering the second flow channel must travel annularly around the alternator to reach the outlet.

    摘要翻译： 交流发电机包括内壳体和外壳体。 位于其间的一对O形环形成具有第一流动通道，第二流动通道和轴向通道的密封流动室。 第一流动通道是沿着交流发电机沿径向延伸的盘形腔。 第二流动通道形成完全围绕交流发电机延伸的环形护套。 轴向通道将冷却剂从第一流动通道引导至第二流动通道。 从轴向通道径向对准的入口允许冷却剂进入第一流动通道，使得进入入口的冷却剂必须沿直径跨越交流发电机流动到达轴向通道。 从轴向通道直径地布置的出口允许冷却剂离开流动室，使得进入第二流动通道的冷却剂必须环绕交流发电机环行进到出口。

    摘要： A stator for a dynamoelectric machine improves the cooling of the stator winding without increasing the size of the stator winding or the entire stator. The stator is of a unique construction wherein the size, and more specifically the cross sectional area or volume of the individual conductors is greatly reduced, while the total number of conductors is increased. In addition, a multiple filar construction is employed to avoid the potential for high levels of inductance and resistance in the conductors and to minimize the interference between the cascaded stator end loops and the housing that surrounds the stator.

    摘要： A rotating machine comprises a housing defining a generally cylindrical bearing pocket and defining an interior and exterior. The machine also includes a bearing retainer having a generally cylindrical sleeve portion retained in the bearing pocket and a bearing having an outer race and an inner race, the outer race affixed within the cylindrical sleeve portion. The machine further has a rotating member mounted on a shaft for rotation therewith, the shaft having a portion affixed within the inner race of the bearing. In one embodiment, the bearing retainer includes anti-rotation keying projections the bearing pocket includes complementary depressions for the keying projections. The keying projections cooperate with the complementary depressions to prevent rotation of the bearing retainer with respect to the bearing pocket. In another embodiment, a cap is affixed to the bearing retainer to substantially prevent contamination from reaching the bearing from the exterior.

    摘要： A light emitting diode (LED) driver case includes a housing, driver circuitry, an recessed area in the housing, and a luminaire disconnect. The luminaire disconnect is coupled to the recessed area in the housing and extends toward an aperture in a top plate of a LED module. The luminaire disconnect can be fixedly or removably coupled to the recessed area in the housing. When the luminaire disconnect is removably coupled to the recessed area, one or more of a number of retaining features can be used to prevent the luminaire disconnect from moving or to limit the movement of the luminaire disconnect.
