Electrical machine including axial connector assemblies and related methods
First Claim
1. An electrical machine comprising:
- a plurality of stator coil ends each having a fluid passageway therein;
a plurality of rings; and
a plurality of axial connector assemblies for connecting the plurality of stator coil ends to said plurality of rings, each axial connector assembly comprisinga header cap comprising an open end received on a respective stator coil end and a closed end opposite the open end, the closed end defining a coil spherical connector portion, and said header cap having a fluid port therein coupled to the fluid passageway of the respective stator coil end,a ring spherical connector portion carried by a respective ring,a pair of connector members receiving therebetween said coil and ring spherical connector potions.

Abstract
An electrical machine may include a plurality of stator coil ends each having a fluid passageway therein. The electrical machine may further include a plurality of rings and a plurality of axial connector assemblies for connecting the plurality of stator coil ends to the plurality of rings. Each axial connector assembly may include a header cap including an open end received on a respective stator coil end and a closed end opposite the open end, the closed end defining a coil spherical connector portion. The header cap may have a fluid port therein coupled to the fluid passageway of the respective stator coil end. A ring spherical connector portion may be carried by a respective ring, and a pair of connector members may receive therebetween the coil and ring spherical connector potions.
