Abstract

An example arrangement for driving a turbomachine includes an input shaft that is configured to rotate a rotor of the turbomachine through a hydraulic log and gear differential rotatable coupled to the input shaft. A motor-generator is rotatably coupled to the differential. The motor-generator has a motor mode of operation and a generator mode of operation. The motor-generator is configured to drive the input shaft through the hydraulic log and differential when the motor-generator is in the motor mode of operation. The input shaft is configured to drive the motor-generator through the hydraulic log and differential when the motor-generator is in the generator mode of operation.
