A method of mitigating whirl on a rotating device includes detecting force on a outer surface of the rotating device and switching the rotating device between a rotating mode and a non-rotating mode. In the rotating mode, the outer surface may rotate with an inner sleeve. In the non-rotating mode, the outer surface may be rotationally isolated from the inner sleeve. The rotating device may include a stabilizer with an active or passive system for switching modes. The stabilizer can include an outer collar, an inner sleeve, and a locking mechanism. The locking mechanism is changeable between a first mode in which the outer collar is rotationally fixed to the inner sleeve and a second mode in which the outer collar is rotationally isolated relative to the inner sleeve. An example passive device may include a magnetic clutch where the detected force overcomes magnetic forces to change mode.
