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 that can be transmitted to the ...

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 perspective, it’s true,...

Ball and lead screw assemblies are often driven by a motor connected in-line with the screw shaft via a coupling. While this mounting arrangement is simple and easy to service, the addition of a non-rigid mechanical component (the coupling) can introduce windup, backlash, and hysteresis — all of which affect positioning accuracy and repeatability. The coupling also adds ...

If your application calls for a Cartesian robot, you have a wide variety of options, depending on the level of integration you want to undertake. And although pre-engineered Cartesian robots are becoming more widely adopted as manufacturers expand their product ranges to fit a broader scope of performance criteria, some applications still necessitate building your own C...

Our 2020 survey of the industry indicates an unabated trend towards more automation of previously static or manually tended systems. Key to these new offerings is installation simplicity for OEMs and end users of linear components for linear axes … as well as positioning stages and Cartesian robots. In fact, Cartesian robots (also called linear robots) increasingly se...

Positioning stages and tables are used in motion control systems to hold down a work piece and/or to position it for some operation. Stages or tables, whether linear or rotary, are most often complete motion sub-systems. That is, they are motion systems themselves composed of a system of motion control components such as linear motion components, motors or actuators, enc...

Many automated machines rely on linear guidance components, such as profiled rail, round rail or other rolling or sliding bearing structures, to guide and support the moving elements of equipment. Additionally, many times these moving elements are driven by some type of linear actuator device. One of the most common issues in linear systems of any kind is misalignment...

While ironless linear motors have been used in semiconductor and electronic applications for more than a decade, they are still viewed by many designers and OEMs as “niche” products. But the perception of linear motors as a costly solution for unique applications is slowly changing, as more industries are adopting them as replacements for ball screws in packaging, assemb...

Linear guides and systems are typically subjected to both linear forces due to downward, upward, and side loads and rotational forces due to overhung loads. Rotational forces — also referred to as moment forces — are typically defined as roll, pitch, and yaw, based on the axis around which the system tries to rotate. To define roll, pitch, and yaw in linear systems, w...

Gone are the days when machine designers and builders had to choose between constructing their own linear system from scratch or settling for a limited range of pre-assembled systems that, in most cases, were an imperfect fit for their application. Manufacturers today offer systems based on a range of drive mechanisms—ball screws, belts, rack and pinions, linear motors, ...

Linear encoders track axis position without intermediate mechanical elements. The encoders even measure transfer errors from mechanical linkages (such as rotary-to-linear mechanical devices), which helps controls correct for errors originating from the machine. Thus, this feedback lets controls account for all mechanics in position-control loops. How photoelectric sca...

Positioning stages today can satisfy specific and demanding output requirements. That’s because customized integration and the latest in motion programming now help stages get incredible accuracy and synchronization.

Here are some tips on how to correctly specify and size a linear-motor-driven actuator using the mnemonic ACTUATOR—short for accuracy, capacity, travel length, usage, ambient environment, timing, orientation and rates—to remember all the key parameters Choosing the right actuator for a given application may seem like an easy task. However, more goes into selecting a r...

Linear actuators come in a wide range of sizes, but over the past several yeas, manufacturers have been emphasizing more and more compact footprints. But no matter how small the actuator, the addition of a motor can make the overall size of the complete system too large for space-constrained applications. Some manufacturers are addressing this issue by integrating a moto...

When choosing a recirculating linear guide, there are several criteria that need to be specified, including size, preload and accuracy. And although the term “accuracy” is often used in a generic sense, when referring to recirculating ball or roller guides, it designates five characteristics: 1. Height tolerance of the rail and block assembly 2. Permissible differenc...

There are many ways to build linear systems for motion in the X, Y, and/or Z directions – also known as Cartesian coordinates. The terms we generally use to refer to these systems depend on how the axes are assembled, where the load is positioned, and to some extent, what type of use the system was designed for. In many industrial applications, Cartesian and gantry-style...

Like many terms used in the linear motion industry – “heavy duty,” “miniature,” and “corrosion-resistant,” to name a few – there is no industry standard that specifies what constitutes a “high speed” linear actuator. Nevertheless, there are some general guidelines that manufacturers follow when classifying and marketing their actuators as high speed. These guidelines are...

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 grouping production work stations as closely as possible to minimize mater...

You’re working on an application that requires linear motion – maybe it’s a pick-and-place assembly system, a packaging line, or a gantry for material transfer – but designing your own actuator from scratch, sourcing the various parts, mounting and aligning the components, and implementing a maintenance system is not an effective use of your time. You begin looking at p...

Specifying the right ball screw for a given application will ensure machine accuracy, repeatability and life while minimizing the total cost of ownership. A ball screw drive translates rotational motion to linear motion or vice versa and can apply or withstand high thrust loads–upward of 750,000 lb static capacity using a Ø6.000 in. ball screw assembly–with efficiency...

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 influence that a linear actuator has on the overall machine design. First of all, in an actuator, the guide an...

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. Positioning accuracy specifies the difference between the system’s target position and the actual position that it reached. Travel accuracy specifies error...

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 cosine sign...

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 requirements, guides and drives with recirculating bearings are a good fit. Case in point: the lead deviation for a common class 5 ball screw is 26 ...

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 provided by the motor’s rotary encoder. For stepper driven systems, which typically operate in open-loop mode with no position f...

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 way today’s positioning stages, rotary tables, and gantry setups are built. These quickly connect electrically and mechanically — and easily network to each other a...

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. When it comes to automated technology, most people tend to think about robots, automated guide vehicles and pick-and-place systems. But just as important are the smaller, simpler structures...

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 requirements. But there are still times when it makes sense, from a financial or technical standpoint, to design and build an actuator in-house. However, the make vs. b...

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 excel at providing axial, or thrust, forces for pushing, pulling, or holding loads. Although their function is straightforward, thrust...

Another area of Mechatronics that is very confusing is the area of actuators. The problem is that you can buy actuators that are assemblies of several components, or you can buy the components, and they’re all called actuators. This is traditionally an ambiguous area of mechatronics and I will try to add a little definition to help clarify things a bit. An actuator as...
