Claim:
1. An axial engagement-controlled variable damper comprising: a rotor assembly coupled to a rotor shaft and disposed about an axis of rotation; a stator, coaxially aligned with, and disposed radially inward of, the rotor assembly; and a flux sleeve, axially movable relative to the rotor assembly between at least a first position and a second position and having a circumferential flange portion disposed radially inward of the rotor assembly and radially outward of the stator, the flux sleeve being configured to alter magnetic coupling between the stator and the rotor assembly in response to being moved axially, the axial-engagement controlled variable damper being configured to generate a first drag torque in response to the flux sleeve being in the first position and a second drag torque in response to the flux sleeve being in the second position.
