|
The enclosed positioning stage is designed for closed position
loop servo applications with one or more axes.
The enclosed stage features a moving coil 3 phase brushless
motor with integral recirculating linear bearing and encoder.
It features heavy duty construction with lightweight moving
parts for higher acceleration.
Abbe error is minimized by centering the linear motor and
encoder between two parallel rails. Multiple bearings support
the payload, moving coil and encoder head. An enclosed or
open linear scale is available to meet customer requirements.
Standard 5 micron resolution is provided.

| The brushless linear motor provides high reliability,
non-contact operation with backlash or component wear. Dynamic
performance with low settling times is provided by the stiffness
of the linear brushless motor.
Enclosed stages can be stacked on top of each other to provide
a multiple axis positioning system. Typically, the wider unit
is used as the base axis for stability and stages with smaller
cross sections stacked on top. |
