Abstract:
A distributed connection ring assembly can be used in a stator assembly and can integrate a neutral connector and jumping winding connections in an overmolded assembly for insulation. The stator assembly including a stator core defining a plurality of slots spaced apart from each other, a plurality of bar conductors disposed in each of the slots, and a distributed connection ring assembly secured to the jumping winding connections. The distributed connection ring assembly includes an overmolded neutral connector. The distributed connection ring assembly also includes a plurality of overmolded couplers circumferentially spaced apart from one another. The overmolded couplers are coupled to the overmolded neutral connector. Each of the plurality of overmolded couplers includes a support body and a plurality of stator conductors partially disposed inside the support body. The stator conductors are electrically connected to the jumping winding connections.
