Abstract: A mounting arrangement for an electrical contactor includes a panel and a post. The post has a first end and a second end protruding from the panel. The first end of the post is arranged to electrically communicate with an electrical contactor. The second end of the post is arranged to connect to an electrical bus bar. A cold plate overlays the panel, extends about the post, and is in thermal communication with the post to transfer heat between the cold plate and post.

Abstract: A rotating machine has a shaft rotatable about an axis, a rotor rotatable with the shaft, and a rotor end winding at an axial end of the rotor. A stator is spaced from the rotor and forms a gap therebetween. The stator comprises a stator winding. A fluid system directs fluid through to the stator. A baffle to diverts fluid away from the gap and toward the stator.

Abstract: An electrical contactor assembly includes an electrical contactor, a post in electrical communication with the electrical contactor, an insulator body, and a heat sink. The insulator body is in intimate mechanical contact with the post. The heat sink is in intimate mechanical contact with the insulator body and is in thermal communication with the electrical contactor through the post and the insulator body such that heat flowing between contactor and the heat sink flows through the post and the insulator body.

Abstract: An electrical machine includes a winding core with a plurality of end slots. A winding is seated in the end slots with end windings where the winding crosses from end slot to end slot. A slot insulator is seated in two of the end slots. The slot insulator includes a first slot liner seated in a first one of the two end slots with a winding slot defined therethrough in an axial direction. A second slot liner is seated in a second one of the two end slots with a winding slot defined therethrough in the axial direction, wherein the second slot liner is spaced apart in a lateral direction relative to the axial direction from the first slot liner by a gap. The slot insulator includes a span portion bridging across the gap to connect the first and second slot liners.
