Abstract
An apparatus according to one embodiment includes a motor having a rotor, a take up reel coupled to the rotor, and a damping layer positioned between the rotor and the take up reel. The damping layer is constructed of a visco-elastic material. An apparatus according to another embodiment includes a motor having a rotor, a clutch coupled to the rotor, and a damping layer positioned between the rotor and the clutch. The damping layer is constructed of a visco-elastic material.
Claims18
An apparatus, comprising:
- a motor having a rotor;
- a take up reel coupled to the rotor;
