When building a machine, OEMs and end-users are faced with the challenge of finding the highest possible precision technology, while meeting demanding price-performance ratios. Learn more about the challenges designers face and what types of linear encoder technology options should be considered … [Read more...]
How to Build a Better Linear Drive System
With advances in precision manufacturing and the advent of electronic preloading, the accuracy and performance of rack-and- pinion drives can match or exceed that offered by competing hardware – often with better durability, efficiency and economics. This paper outlines four key areas for comparing … [Read more...]
Forms of Closed Loop Stepper Control
This White Paper will explain the three methods that are used to close the feedback loop around stepper motors in a control system. … [Read more...]
Robotics and DualVee® Go Hand in Hand
Robotics and DualVee go together like peas and carrots! Why? Because DualVee can handle high load capacities in all sorts of environments. Did we also mention that DualVee double row ball bearings are internally lubricated as well as sealed and shielded? Say hello to lower maintenance cost! … [Read more...]
Linear Guide Track Designs
The primary function of a linear guide system is to enable an application payload to be easily moved in one linear direction (the linear guide system’s travel axis) while constraining motion in all other directions. Motion constraint is achieved through multiple points, lines, or planes of contact … [Read more...]
Learn how mechanical linear motion hardware affects precision motion control
While there's a lot of focus on electronic controllers that can handle nano-level positioning or multi-axis synchronization, Rexroth explains how choices machine designers make in mechanical linear motion components are critical in achieving the best accuracy possible. Mechanical systems must be … [Read more...]
4-point bearings do triple duty while saving space
A four-point contact ball bearing is ideal for oscillating movement at slow to moderate speeds, and can replace two angular contact bearings. A white paper from Kaydon Bearings, an SKF Group brand, explains the advantages (greater accuracy; space, weight, and cost savings) with design tips. … [Read more...]
Application Note: Servo PID Tuning
Let’s take a look at a practical tuning exercise and take a closer look at the real effect of the various gains. Digital servo drive and motor with encoder feedback will be used to illustrate the effects of the various gains, as well as to provide some practical guidelines. One of the best ways … [Read more...]
Important Factors to Consider when Choosing a Rotary Indexer
When it comes to the manufacturing of indexers, there are many ways to achieve movement of mass. Whether extremely light inertia loads or loads in the hundreds of thousands of kgm2. Whether it is rotating, lifting or pushing, there are many variables to consider when choosing a robust solution that … [Read more...]
Linear Guides For The Next Generation Of Medical Machines
Not too long ago, the motion systems used in medical and lab automation equipment had technical requirements that were easy to satisfy. These lightly loaded applications generally required simple point-to-point moves with low to moderate positioning accuracy requirements. However, medical motion … [Read more...]
