Zusammenfassung:	Electrical machines, components thereof, and methods for manufacturing the same are provided. In one aspect, methods for additively manufacturing a rotor assembly for an electrical machine is provided. The method includes additively printing the rotor core and shaft of the same material composition. In another aspect, an electrical machine is provided. The electrical machine includes a stator assembly that includes a stator core having a plurality of poles with magnetic slot wedges positioned between adjacent poles to reduce tooth harmonics. The electrical machine also includes a rotor assembly having a rotor core that is formed as a solid core. In yet another aspect, a rotor assembly for an electrical machine is provided that includes slots that reduce eddy current losses in the rotor core during operation of the electrical machine.
