Closed loop mover assembly with measurement system

摘要

A mover assembly (16) that moves or positions an object (12) includes a mover output (226), an actuator (230), and a measurement system (20). The mover output (226) is connected to the object (12), and the actuator (230) causes the mover output (226) to rotate about a first axis and move along the first axis. In this embodiment, the measurement system (20) directly measures the movement of the mover output (226) and provides feedback regarding the position of the mover output (226).
