Linear Stage Buyers Guide
Consider the following factors when buying a motorized precision linear stage:
Load Capacity, Stiffness, and Size
Consider the size, mass, and inertia of the object that the linear stage will need to move. A miniature stage might have the right on-center load capacity, but a lengthy, off-centered load could provide too much torque for the bearings to handle. A stage with a higher load capacity will provide a longer lifetime in high duty cycle applications.
Bearing Type
In general, cross-roller bearings provide higher load capacity and better geometric performance than ball bearings. Air bearings provide the highest accuracy and lifetime since they are friction-free and maintenance -free.
Travel Range
This refers to the total distance that the stage can move. When stacking stages for XY applications, consider the bottom stage to have a relatively wide base compared to the travel range of the top stage to reduce bending moments.
Acceleration and Speed
Higher velocity and acceleration can be achieved with direct-drive stages. Lead-screw or ballscrew driven stages can provide higher force. The motor size and motion control will have a big influence on step-and-settle performance.
Accuracy, Repeatability, and Resolution
Stages with linear encoders typically provide higher accuracy and repeatability compared to motor mounted rotary encoders or open loop stepper motors. Linear encoders with nanometer resolution are available today.
Drive Mechanism
The following drive mechanisms are offered -- Lead screws (self locking), ball screws (lower friction than lead screws), linear motors (highest velocity and accuracy, ideal for industrial 24/7 applications), or piezo motors (compact, high resolution, self locking).
Environment Suitability
For vacuum applications, special designs are necessary. Air bearings are ideal for clean rooms. Special protection is required for harsh industrial environments.
Support and Warranty
Check the level of technical support provided by the manufacturer, as well as the warranty terms. Always discuss your requirements with a knowledgeable engineer at the manufacturer or supplier to ensure you choose the most suitable stage for your application.
How Does a Linear Stage Work
Typically, objects can rotate along any of three axes, giving the object six degrees of freedom: three rotational and three translational. The linear stage restricts five of these axes, allowing the object to move on only one translational axis. When used properly, the linear stage provides a superior finished product quickly and efficiently.
The stage is comprised of a platform and base that are conjoined by a guide or linear bearing. This joining restricts the platform to linear motion. A linear stage also commonly utilizes a stepper motor. A stepper motor is a brushless, synchronous electric motor that can convert digital pulses into mechanical shaft rotations. A lead screw or worm gear drive are often accompany of a stepping motor to further linear motion control. For best results, a step motor can be used in conjunction with a stepping motor driver in microstep mode.
