In X-Y positioning applications, such as automated pick-and-place, rotary encoders provide feedback on two axes of motion in order to determine X-Y coordinates. The encoder can be attached to the shaft of a ball screw or the drive motor of an actuator.
How do XY stages work?
Also known as XY stages, XY tables are motorized linear slides with linear motion based in bearings which are driven by a drive mechanism, typically a linear motor. XY tables are built and configured to provide high-performance positioning along multiple axis.
What is an XY motor?
Piezo motor-driven positioning stages differ from traditional piezo stack/flexure guided nanopositioning systems. They combine elements of classical motorized positioners such as cross roller bearings, long travel ranges etc.
