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： 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： An assembly (30) for use with a rotating electric machine has a first injection-molded plastic part (32), a second injection-molded plastic part (34), and a third injection-molded plastic part (36). Parts (32, 34) are a bearing sleeve and a brush holder respectively, while part (36) is a cap. The bearing sleeve has a transverse wall (138) from which channels (146, 148) extend in one direction. A cylindrical wall extends in the other direction to form a bearing cup (136) for receiving a bearing assembly. The brush holder has two side-by-side brush guides (62, 64) each containing a respective brush (38, 40). It also has two channels (110, 112) that interlock with the channels of the bearing sleeve to accurately and rigidly place the two parts (32, 34) in assembly. The cap closes an axial end of the bearing sleeve and attaches to the brush holder. The parts are further characterized by various structural features, as well as fabrication and assembly methods.

摘要： A rotor for an electrical machine according to one embodiment of the present invention includes first and second individual slip rings mounted on a rotor shaft. A first end of the coil wire for the rotor passes through a first axial passage in the first slip ring and is terminated to conductive material on an axial end of that slip ring. The other end of the coil wire passes through a second axial passage in the first slip ring and through an axial passage in the second slip ring and is terminated to conductive material on an axial end of the second slip ring. The second axial passage of the first slip ring is electrically insulated from the conductive material of that slip ring, so the second wire end does not inadvertently short-circuit to the first conductive material. Also, the first and second slip rings are each designed to cooperate in providing a gap therebetween which provides space to accommodate the termination of the first wire end onto the axial end of the first slip ring.
摘要翻译：根据本发明的一个实施例的用于电机的转子包括安装在转子轴上的第一和第二单独滑环。用于转子的线圈线的第一端通过第一滑环中的第一轴向通道并且终止于该滑环的轴向端部上的导电材料。线圈线的另一端穿过第一滑环中的第二轴向通道并且穿过第二滑环中的轴向通道并且终止于第二滑环的轴向端部上的导电材料。第一滑环的第二轴向通道与该滑环的导电材料电绝缘，因此第二线端不会无意地与第一导电材料短路。而且，第一和第二滑环各自被设计成协作以在它们之间提供间隙，其间提供空间以容纳第一线端部到第一滑环的轴向端部的端接。
