XY and XYZ Linear Stages for Multi-Directional Motion

Linear motion positioning applications can often be addressed with a single-axis linear stage consisting of a moving rail, a fixed base, a carrier plate, and a linear actuator. However, a sizable number of applications require linear motion on multiple axes.

Liner Stages Provide Linear Motion Position Control on Multiple Axis

Linear motion positioning applications can often be addressed with a single-axis linear stage consisting of a moving rail, a fixed base, a carrier plate, and a linear actuator.  However, a sizable number of applications require linear motion on multiple axes.  For position control in more than one direction, the use of two-axis XY linear stage, or three-axis XYZ linear stage is required.

In its simplest form, an XY linear stage is created by precisely joining two single-axis stages. Mounted perpendicular to one another, the top of the lower axis serves as the upper axis base. The three-axis XYZ stage adds a third dimension of travel using the same technique.  In each individual stage, a hybrid stepper motor linear actuator is combined with a precision lead screw or ball screw and nut to move the carriage to a precise destination point in the linear motion system.  A multi-axis linear stage allows precise, highly accurate, repeatable motion within small design envelopes. 

Several common uses for multi-axis linear stages include:

  • Pick-and-place packaging applications
  • Pipetting and vial handling in medical devices
  • Industrial routers
  • Laser cutting machines
  • Water jet cutting systems
  • UAV launching and landing systems
