Abstract
A micro-actuator including a skeleton having flexible beams, a rotor portion, a stator portion, and a damping material. The flexible beams connect the rotor portion to the stator portion and the damping material is applied to the skeleton. The damping material provides a protective layer to the flexible beams of a micro-actuator. The damping material increases the damping characteristics of the micro actuator and limits the penetration of humidity into the skeleton of the micro actuator.
Claims23
A micro-actuator compirising:
- a skeleton having structural openings therein for forming flexible beams, the skeleton also having a rotor portion and a stator portion, the flexible beams connecting the rotor portion to the stator portion;
- and
- a damping material, the damping material positioned only on the skeleton.
A disc drive comprising:
- a micro actuator having a skeleton having flexible beams, a rotor portion, and a stator portion, the flexible beams connecting the rotor portion to the stator portion;
- and
- a damping material, the damping material applied to only the flexible beam to limit the penetration of humidity into the flexible beam.
A method for damping a micro-actuator comprising the steps of:
- providing a skeleton having a rotor portion and a stator portion, wherein a flexible beam connects the rotor and stator portions;
- applying a dampening material only to the skeleton;
- and
- using the skeleton in the micro-actuator.
A micro-actuator comprising:
- a skeleton having flexible beams, a rotor portion and a stator portion, the flexible beams connecting the rotor portion to the stator portion;
- and
- means for dampening the mass spring frequency of the skeleton.
