THREE PIECE COOLANT CONTROLLED ROTOR SHAFT

原文（中文）

Systems are provided for a rotor assembly for an electric machine. In one example, a system includes a rotor shaft assembly, comprising a shaft; a shaft end cap having two co-axial concentric tracks with a trough therebetween at a first end of the shaft end cap, where the shaft end cap is coupled to the shaft via two co-axial concentric weld beads at the two co-axial concentric tracks of the shaft end cap; and a flow insert arranged in a cavity shaped by the shaft and the shaft end cap, where the flow insert is formed at least in part of plastic.
