The present disclosure relates generally to an energy capture for an electric drive machine, and more particularly to systems and methods for capturing energy during braking of the electric drive machine. In some examples, the disclosure describes an energy capture device including at least two planetary gear assemblies. The first planetary gear assembly can be operatively coupled to an engine, and can engage and disengage, via a first overrunning clutch, a shaft coupled to a generator. The second planetary gear assembly can be at least partially fixed to the first planetary gear assembly, and can engage and disengage, via a second overrunning clutch, the shaft. The first overrunning clutch can disengage the shaft and the second overrunning clutch can engage the shaft during a braking period.
