Drive arrangement for a turbomachine

Abstract

A drive arrangement 50 for driving a turbomachine (10, fig. 3) includes an input shaft 48 that is configured to rotate a turbomachine rotor (40, fig. 2). A hydraulic log assembly 58 is rotatably coupled to the input shaft, and a motor generator 54 is rotatably coupled to the hydraulic log assembly. 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 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 when the motor generator is in the generator mode of operation. The hydraulic log assembly may be configured to adjust the rotational input from the motor generator to drive the input shaft when the motor generator is in the motor mode of operation.
