Abstract:

An actuation system includes a prime mover, a mechanical option module, an actuator, and a controller. The prime mover includes a drive shaft. The mechanical option module includes a housing, an input shaft coupled to the drive shaft, an output shaft, and a planetary gear module. The planetary gear module includes a sun gear coupled to the input shaft, a planet carrier coupled to the output shaft, an outer ring, and planet gears meshed with the sun gear and the outer ring. The application-specific module is connected to the housing and configured to selectively influence movement of the outer ring of the planetary gear module. The actuator includes an actuator input shaft coupled to the output shaft of the mechanical option module. The controller controls an operation of at least one of the prime mover, the mechanical option module, and the actuator.
