摘要：Electrical machines, components thereof, and methods for manufacturing thesame are provided. In one aspect, methods for additively manufacturing a rotor assembly

for an electrical machine is provided. The method includes additively printing the rotorcore and shaft of the same material composition. In another aspect, an electrical machineis provided. The electrical machine includes a stator assembly that includes a stator corehaving a plurality of poles with magnetic slot wedges positioned between adjacent polesto reduce tooth harmonics. The electrical machine also includes a rotor assembly havinga rotor core that is formed as a solid core. In yet another aspect, a rotor assembly for anelectrical machine is provided that includes slots that reduce eddy current losses in therotor core during operation of the electrical machine.
