Description
The Dover Motion XYR™ stepper motor stage features a specialized monolithic center that couples the upper and lower axes, making the stage stiff and compact and machining in orthogonality between the axes. Both motors are mounted to the center section and move with the lower axis only. Motors, knobs, couplings, Hall effect end of travel limits, and screw locking connectors are included.
There are two grades of lead screws available, commercial and precision, depending on the requirements of the application, and linear or rotary encoder feedback can be added for increased positioning accuracy. For applications where a ball screw positioning stage is preferred, see Dover Motion’s XYRB series.
