A mover assembly () that moves or positions an object () includes a mover output (), an actuator (), and a mover housing assembly (). The mover output () is connected to the object (), and the actuator () causes the mover output () to move. The mover housing assembly () seals many of the other components of mover assembly (), including the actuator () within a clean, nonvolatile, housing chamber () that isolates all contaminants from the outside working environment.

Sealed mover assembly

A mover assembly () that moves or positions an object () along a first axis includes a motor () and a coupling assembly (). The motor () includes a motor output () that is moved along the first axis and about the first axis. The coupling assembly () includes a stage () that couples the motor output () to the object () and a stage guide () that guides the motion of the stage () along the first axis. In one embodiment, the stage guide () is a linear bearing that allows for motion of the stage () along the first axis and inhibits motion of the stage () about the first axis, along a second axis and along a third axis. Additionally, the coupling assembly () can include a measurement system () that monitors the movement of the stage ().
