1.4. Vacuum Operation
Contact the factory for information regarding operation in a vacuum environment.
Preparation and considerations for operation in a vacuum environment:
l
Lubrication with vacuum-compatible lubricants
l
Use of materials, fasteners, and coatings with vacuum outgas performance compatible with the level of
vacuum specified
l
For high vacuum stages, elimination of situations that may allow gases to become temporarily trapped
during pump down
l
Extensive cleaning prior to assembly in a clean environment and packaging in a special polyethylene
bag
l
Use of components able to withstand elevated temperatures (non-operating) for bake-out performances
Reduced air pressure eliminates significant convective heat transfer. This, coupled with the viscous
vacuum-compatible lubricants, could result in excessive motor operating temperatures. Because of this,
consider all continuous torque ratings to be
40 to 60% lower
than the value specified for operation in normal
atmospheric environment. Reduce motor usage accordingly.
1.5. Export Restrictions
The AMG150LP and AMG200LP are export controlled by United States Commerce Department export
regulations. If you are from a non-US country and wish to purchase these gimbals, contact Aerotech to
determine if an export license is required to purchase these products. People in countries embargoed by the
United States cannot purchase and import these products.
