How to Estimate Your Linear Actuator Needs with Minimal Application Data?
High moment loads can dictate the use of a dual-rail style linear actuator. Selecting an actuator based on approximations of the performance requirements is arguably more risky than choosing a linear guide or drive with minimal application info. But still, the situation is quite common where a d...Read more -
Does my system need high accuracy or repeatability (or both)?
Component selection and machine design affect system accuracy and repeatability. Before we answer this question, let’s define accuracy and repeatability for linear systems. 【Accuracy】 In linear motion, there are two generally categories of accuracy – positioning accuracy and travel accuracy. P...Read more -
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...Read more -
Linear Systems for Nanopositioning
Piezo actuators, Voice coil actuators, Linear motor stages. When we talk about linear motion, we typically discuss applications where the travel distance is at least a few hundred millimeters, and the required positioning is in the range of a few tenths of a millimeter. And for these requirement...Read more -
FAQ: What types of linear encoders are there and how do I choose?
Absolute or incremental, Optical or magnetic. Linear encoders monitor linear movement and provide position feedback in the form of electrical signals. In servo driven systems, linear encoders supply the precise position of the load, typically in addition to the speed and direction feedback provi...Read more -
What To Do When Your Motion System Throws You a Curve
Guide-wheel based ring and track systems are more compact and offer better positioning accuracy and more options for cargo carrying positions than alternative conveyor systems for curvilinear applications. In the ongoing drive to reduce production costs, one trend at manufacturing facilities is ...Read more -
Positioning stages and gantries — new trends in integration approaches
The linear, rotary, XY, or vertical-lift stage integrates motor, drive, and controller. There’s demand for motion designs offering simplicity or turnkey operation, so component suppliers are now doing much more integration for OEMs and plant engineers. Nowhere is this more evident than in the wa...Read more -
Simple support structure improves warehouse packaging efficiency
An improvement in packaging efficiency required attention to ergonomics, ease of assembly, and cost efficiency. Automation is changing how traditional distribution centers operate as companies search for new ways to maximize their efficiency, increase order accuracy and fulfill customer demand. ...Read more -
What is an LED Matrix Screen?
High-end LED Billboard Subversives. The dynamic ups and downs of each module of the fuyu LED matrix screen combine with the video screen to form different creative combinations. The terminator of two-dimensional plane advertising leads the epochal wave of media replacement and advertising apprec...Read more -
How to estimate your linear actuator needs with minimal application data
Load, Accuracy, Speed and Travel. Choosing linear motion components during the development phase of a project has been a source of frustration for designers and application engineers for decades—especially when it comes to complex subassemblies such as linear actuators. Consider for a moment the...Read more -
Which type of linear actuator is best for thrust forces?
Electromechanical designs in motion control applications. When an application requires pure thrust forces, the best type of linear actuator is often a rod-style actuator. Also referred to as “thrust actuators” and (when a motor is integrated) “electric actuators,” these electromechanical devices...Read more -
Linear Actuators: the Make vs. Buy Decision
Business evaluation, Manufacturing and assembly requirements, Customer support needs. With the range of linear actuators on the market, it’s becoming easier for machine builders and end users to find a standard or “customized standard” product that meets even the most unique application requirem...Read more
