1. A surgical instrument module for powering a plurality of discrete surgical end effectors, the surgical instrument module comprising:
a motor having a rotatable motor shaft defining a longitudinal axis;
a main sun gear fixed to the motor shaft and configured to rotate with the motor shaft;
a first planetary gear assembly operably coupled to the main sun gear such that the first planetary gear assembly rotates about the longitudinal axis in response to a rotation of the main sun gear;
a second planetary gear assembly operably coupled to the first planetary gear assembly such that the second planetary gear assembly rotates in response to the rotation of the first planetary gear assembly;
a drive shaft having a proximal end portion non-rotatably coupled to the second planetary gear assembly, and a distal end portion, the drive shaft being configured to rotate with the second planetary gear assembly;
a high-torque output configured to be operably coupled to a driven member of a first type of surgical end effector, the high-torque output being operably coupled to the motor; and
a high-speed output configured to drive an operation of a second type of surgical end effector, the high-speed output being non-rotatably coupled to the distal end portion of the drive shaft such that the high-speed output rotates with the drive shaft.
