An aircraft is provided and includes a non-rotating frame, an engine disposed in the non-rotating frame, a rotating frame, which is drivable by the engine to rotate relative to the non-rotating frame to generate lift and thrust, the rotating frame including a hub and rotor blades extending outwardly from the hub, an actuation system including electro-mechanical actuators (EMAs) respectively disposed in the rotating frame between the hub and the rotor blades, each EMA including a rotary inductive device, a gear train associated with each EMA and the corresponding rotary inductive device to convert linear displacements of a piston responsive to rotor blade lead/lag into rotation of the rotary inductive device and a controller that controls the rotary inductive device to operate, in a first mode, as a motor which drives the gear train, and, in a second mode, as a generator which is driven by the gear train.
