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： An liquid-cooling system for an electrical machine comprises a rotor mounted on a shaft for rotation therewith and defining an axis of rotation, and a stator disposed coaxially with and in opposition to the rotor. The stator has stator windings, the stator windings having an axially-extending portion. The electrical machine further comprises a housing enclosing the stator and the rotor, the housing having an axial end, the axial end having a wall with an inner surface and an outer surface. The electrical machine also includes a cooling tube having a first end and a second end and an embedded portion thereof embedded between the first inner surface and the first outer surface, the embedded portion of the cooling tube located in substantial axial alignment with the axially-extending portion of the stator windings. In another aspect of this design, the inner surface of the wall of the axial end of the housing is substantially flat and is separated from an axial end of the rotor by an air gap. In a third aspect of this design, the housing of the electrical machine comprises a front housing portion and a rear housing portion. The front housing portion defines a first circumferentially-extending channel which encloses a first axially-extending portion of the stator windings and the rear housing portion defines a second circumferentially-extending channel which encloses a second axially-extending portion of the stator windings. Designs as disclosed herein provide effective cooling of an electrical machine while supporting packaging-efficient electrical machine designs.

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 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： An automotive vehicle includes an engine, a plurality of electrical load subsystems, and at least one controller. During an auto start of the engine, the at least one controller detects a starter disengage condition. In response to detecting the starter disengage condition, the at least one controller periodically determines a value of an operating parameter associated with the vehicle, causes a first subset of the electrical load subsystems to be enabled when the value of the operating parameter falls with a first predefined range of values, and causes a second subset of the electrical load subsystems to be enabled when the value of the operating parameter falls within a second predefined range of values.

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.
