<p>A rotor (112) for use in a high speed electrical machine includes a shaft (302), a plurality of poles (304a-i), a plurality of coils (306a-d), and a rotor crossover (516, 716) that is relatively flexible, and that does not crack under the centrifugal forces and the mechanical and thermal cycles encountered during machine operation, startup, and shutdown. The poles (304a-i) extend radially outwardly from the shaft (302) and are spaced apart from each other to form an interpole region (305), and the coils (306a-d) are wrapped around the poles (304a-i). The rotor crossover (516, 716) is coupled between selected ones of the coils (306a-d), and includes a stranded wire conductor (518) and an insulator (606).
