How to Reduce the Effects of Stiction (stick-slip) in Linear Guides
What causes stiction? How to reduce them. Unless you’re playing the violin, stiction, or stick-slip, is an unwanted condition caused by the difference between static and dynamic friction between the two surfaces. When stiction occurs in linear guides, it can lead to chattering (“jerky” motion), seized motion, fluctuating torque requirements, or a loss of accuracy in the form of overshooting. W...
What are Rail Brakes and When Should You Use them?
How to Select and Apply Rail Brakes The servo and stepper motors that drive linear motion systems often include a braking function, or, in the case of stepper motors, detent torque that helps prevent the motor (and, therefore, the load) from moving when powered off. But in some applications, a secondary brake is required — either to provide redundancy and meet safety requirements or to hold th...
How to Specify Pulleys for Synchronous Belt Drives
High speed and precision belt driven system design. When designing a belt drive system, the first step is to choose the most suitable belt for the application. But the pulleys also play an important role in the performance of the belt — especially in synchronous belt drive systems, where proper meshing of the belt teeth with the pulley grooves can affect everything from the amount of torque th...
Pushing the Limits of Linear Accuracy
Straight, accurate movement is far from easy. Straight, accurate movement is far from easy, and linear positioning devices prove it by erring in not one, but three dimensions Just when you thought you had the “linear motion” concept nailed down – hit the required points on the straightaway and you’re home – along comes the remaining five degrees of freedom to crash the party. From a coarse per...
What Options are There for Integrated Motor and Screw Designs?
External motor-screw integration, Non-captive motor-screw integration and Captive motor-screw integration Ball and lead screw assemblies are often driven by a motor connected in-line with the screw shaft via a coupling.

Positioning accuracy specifies the difference between the system’s target position and the actual pos...
What is sub-divisional error (SDE) in linear encoders?
Accuracy of the interpolation. To determine the position of a linear axis, an encoder read head travels along a scale and “reads” changes in light (for optical encoders) or magnetic field (for magnetic types). As the read head registers these changes, it produces sine and cosine signals that are shifted 90 degrees from each other (referred to as “quadrature signals”). These analog sine and cos...
