Abstract
A connector assembly that mechanically and electrically connects respective ends of first and second stator coil sections includes first and second clip assemblies, first and second connector bar assemblies, and first and second coupling structures. The first clip assembly includes first and second clip members and the second clip includes third and fourth clip members. The first and second connector bar assemblies are coupled to the first and third clip members and to the second and fourth clip members, respectively, to structurally couple the first stator coil section to the second stator coil section. The first clip member, the first connector bar assembly, and the third clip member create a first path for electric current between the stator coil sections, and the second clip member, the second connector bar assembly, and the fourth clip member create a second path for electric current between the stator coil sections.
