Abstract
The present invention is an insulating end cap which provides mechanical support to the end turns of the coils. The mechanical support provides insulation by axially, radially and diametrically separating end turns of coils within phases, and end turns of coils of different phases. Additionally, mechanical insulative support is given to coil-to-coil crossovers and also to coil-to-terminal connections. The end cap may be formed integrally by an injection molding method. Further, the end cap removes the need for a cuffed, grain-oriented insulative lamination stack slot liner by providing support for the liner. The liner becomes independent of stack length. The end cap is designed to be symmetrical and one end cap design is suitable for use at both ends of an armature.
