Electrical machine including axial connector assemblies and related methods

An axial connector assembly for connecting a stator coil end to a ring of an electrical machine, each stator coil end having a fluid passageway therein, the axial connector assembly comprising:

• a header cap comprising an open end to be received on the 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 to be coupled to the fluid passageway of the stator coil end;
• a ring spherical connector portion to be carried by the ring;
• and
• a pair of connector members to receive therebetween said coil and ring spherical connector potions.

A method for axially connecting a stator coil end to a ring of an electrical machine, each stator coil end having a fluid passageway therein, the method comprising:

• installing a header cap comprising an open end onto the stator coil end and a closed end opposite the open end, the closed end defining a coil spherical connector portion, and the header cap having a fluid port therein coupled to the fluid passageway of the stator coil end;
• installing a ring spherical connector portion onto the ring;
• and
• joining a pair of connector members together and receiving therebetween the coil and ring spherical connector potions.
