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.
