Abstract
There is described an epicyclic gear system and method of a flow control actuator for providing selectable torque and speed ranges. The epicyclic gear system comprises an input shaft, a gear engagement system, and an output shaft. The input shaft is configured to receive an input rotational motion. The gear engagement system is configured to receive a gear ratio command from a clutch mechanism and restrict movement of one or more gears of multiple planetary gears in response to the gear ratio command. The output shaft is configured to provide an output rotational motion based on the input rotational motion at the input shaft. The output rotational motion is different from the input rotational motion in response to restricting movement of one or more gears of the planetary gears.
