Abstract
The present disclosure provides a vibration damper for an actuator assembly. One exemplary embodiment relates to an actuator assembly including a magnetic assembly configured to produce a magnetic field and an actuator movable relative to the magnetic assembly in response to the magnetic field, wherein the actuator includes a vibration damper which interacts with the magnetic field.
Claims20
An actuator assembly comprising:
- a magnetic assembly having at least one component configured to produce a magnetic field;
- and
- an actuator movable relative to the magnetic assembly in response to the magnetic field, the actuator having a first damping magnet embedded in a damping material.
An actuator assembly comprising:
- a magnetic assembly adapted to generate a magnetic field, the magnetic assembly including a first magnetic assembly component spaced apart from a second magnetic assembly component to define a gap there-between;
- and
- a positioning assembly disposed in the gap and configured to interact with the magnetic field to move the positioning assembly with respect to the magnetic assembly, wherein the positioning assembly comprises:
- a first damping magnet attached with a first damping material to an edge portion of the positioning assembly.
