Abstract
An electric machine includes a shaft and a rotor carried by the shaft and having a rotor body, a plurality of rotor windings carried by the rotor body, and a retaining ring surrounding the rotor windings adjacent an end of the rotor body. An electrically conductive stud extends radially outwardly from the shaft adjacent the end of the rotor body. An electrically conductive member includes a first end section coupled to the electrically conductive stud and having a loop shape, a second end section coupled to a corresponding one of the rotor windings, and an intermediate section between the first and second end sections. An insulation assembly is between the shaft and the retaining ring and surrounding the intermediate section to define at least one gap with adjacent portions thereof.
