1. A method for operating a turbomachine, the method comprising:
rotating a first rotatable component at a first speed, wherein the first rotatable component comprises a first compressor, and wherein the first rotatable component is operably coupled to a first electric machine having a first rotor assembly and a first stator assembly, the first stator assembly constituting a portion of a fixed stator assembly;
rotating a second rotatable component at a second speed, wherein the second rotatable component comprises a second compressor, and wherein the second rotatable component is operably coupled to a second electric machine having a second rotor assembly and a second stator assembly, the second stator assembly constituting another portion of the fixed stator assembly, the fixed stator assembly disposed between the first rotatable rotor assembly and the second rotatable rotor assembly; and
transferring energy generated from at least one of the first electric machine or the second electric machine to adjust the first speed or the second speed based on a compressor map determinative of a desired operating condition relative to one or more of a stall margin, a surge margin, an operating pressure ratio, or an operating speed.
