Automating the squeeze: Tolomatic prototype improves on hand-held emergency ventilator for COVID-19 patients
Our prototypes use electric linear actuators to automate a hand-held, portable and non-invasive emergency ventilator. The advantage of screw-driven linear actuators is that they provide smooth and consistent operation--allowing the device to control the velocity, the acceleration and the distance of any move at any point in time. This controlled motion allows for a more continuous volume of air per compression cycle and a more typical breathing cycle.
As a designer, you may be faced with an application in which you have to carry and support a load as well as move it. These are ideal applications for rodless electromechanical actuators.
While determining which rodless actuator model will suit your needs, you'll also need to select the type of drive: belt or screw. This blog will briefly explain these drive systems and summarize their advantages and disadvantages
There’s a debate in the machine design community about what’s the best linear motion technology—electric or pneumatic. There are proponents on both sides. As a manufacturer of both electric and pneumatic linear actuators, we’d like to bring some balance to the discussion.
Electric linear motion has benefits as do pneumatic solutions. This blog will give you eight factors to consider when you’re making this important selection
When you’re faced with designing a new piece of automation equipment, you have a lot on your mind. Concerns like performance requirements. How to design flexibility into the machine. How to keep costs down. How to pack the performance needed into a compact package.
You can rely to electric linear actuators to address these issues. They have inherent flexibility and long-term cost-efficiency. Once you choose electric linear motion, you can select either an integrated linear actuator or a traditional design. Both options have pluses and minuses that we’ll review here.
Innovate with linear motion: Online resource for integrating electric actuators into machine designs
For every application a machine designer tackles, they have to consider a unique set of requirements. Evaluating a variety of linear motion attributes is key to determining the optimal solution.
It was a rough week for the whole team working on a new customer’s new machine design. Finally, it’s Friday night and you sit down on the couch to relax with your friends. You made some popcorn and just popped in a DVD recommended by your parents. They told you it’s a classic and might be a bit slow but it has a good story. The movie starts and after 30 seconds, your friends are giving you confused looks. The movie is very difficult to watch because it is filmed in stop motion. The images on the screen are frozen and jump from one to the next. Sometimes it is half a second between shifts and sometimes it can be several seconds. You can see the evening disintegrating and quickly move to switch out the movie to ‘The Fast and the Furious’ for some non-stop action.
Some components are more mission-critical than others. A main worry of machine design engineers is making equipment that will last and avoiding need for field service calls to diagnose issues and replace failing components. At their core, electric linear screw actuators deploy mechanical technology such as ball bearings, ball screws and roller screws that have a finite life. These components do not last forever, even though that is the expectation of some customers. When asked “How long will this actuator last?” we provide our customers with a way to calculate, estimate and size the electric linear screw actuator to achieve the desired life for their applications.
Many industrial applications call for linear actuators. After gathering the data, the designer faces a crucially important choice early on – whether an electric rod actuator or rodless electromechanical actuator is best. If a rodless actuator is the choice, there are several factors the designer considers in final selection.
Sometimes the electric linear actuator an OEM machine designer needs is right there in the catalog. But other times nothing standard fills the bill. When a standard product meets 90% of your application’s needs, often product modification can get you the final 10%. To get to 100%, though, an OEM needs an experienced, innovative and knowledgeable linear actuator partner.
The trend in industrial component sourcing is to eliminate waste, reduce costs and improve efficiency. This often means consolidating suppliers into single-source relationships. Single sourcing can build stronger relationships with suppliers, boost system performance and increase the speed of procurement.
Machine designers can use a single-source approach to reduce time spent on sourcing, installing and testing electric linear motion systems.
Keeping things clean is a top concern in food and beverage processing operations because food safety is crucial. The Food Safety Modernization Act (FSMA), with its emphasis on preventing foodborne illness, puts even more pressure on food producers. Machine designers who serve this industry need to incorporate components that meet the industry’s demands. When it comes to electric linear actuators, there are several things a design engineer needs to consider, especially if the machine will be subjected to periodic washdowns.
Linear actuators are familiar components in many factory automation systems. They’re one of the usual suspects in any line-up of linear motion components.
There’s a lot riding on specifying the right linear actuator for the task. Choose well and it’s smooth sailing. The actuator performs without a glitch for a long time. Choose the wrong one, and it’s a bumpy ride. You can wind up with break-downs and poor product quality.
When you specify a linear actuator, some basic decisions come first. Like electric or fluid-powered?Like do you need the push/pull of an electric rod actuator or the load-carrying action of a rodless electromechanical actuator?
We’ve compiled tips for selecting these actuator types. Here’s an opportunity to increase your knowledge of electric linear motion.
There’s a new debate in motion among machine designers. What’s best? Pneumatic or electric linear actuators? The truth is it depends on the application. What follows is an honest comparison of linear actuator choices – an assessment of strengths and weaknesses – so you can choose what’s best for your project.
Linear actuators are common and critical elements in many industrial machines and automation systems. With so many choices on the market, it’s important to know how to select the best one for your application.
You probably know a lot about linear actuators. But do you know everything? Our electric linear actuator quiz will test your engineering smarts.
In many applications electric rod actuators are a great solution. Compared to pneumatic or hydraulic cylinders, electric linear actuators offer more control over application parameters like position, velocity, and force. They deliver high degrees of accuracy and repeatability and can handle complex motion profiles. All things considered, an electric rod actuator is often the superior actuation choice.
There are lots of good reasons for specifying an electric rod actuator. Electric linear actuators offer a high degree of control over application parameters like position, velocity, and force. They deliver high degrees of accuracy and repeatability and can handle complex motion profiles. All things considered, an electric rod actuator is often a superior actuation choice compared to pneumatic or hydraulic cylinders.
The length of time a linear actuator will function (i.e., service life) is critically important to a machine designer. Machines need to keep working reliably with little or no need for lengthy maintenance that will take a machine off-line . So, components like actuators must keep working.
Some linear actuator application requirements mean you have to go long. Long stroke, that is. Length of stroke is a critical factor in electric linear actuator selection. While some applications require moves of just inches or a few feet, others require moves of 10 feet or more. For an application requiring this kind of long stroke linear actuator, a belt driven rodless electromechanical actuator will be your solution.
Space is at a premium in most manufacturing operations. And of course, saving money is a constant goal. Plant managers are looking for ways to save money and space, so machine designers are tasked with creating ever more compact, affordable systems.
A new class of products addresses the needs for lower cost and efficient use of space: the integrated servo motor/controller/drive. These systems combine a servo motor and controller with a servo drive. They’re compact and eliminate the need for a drive cabinet.
Keeping clean is important, right? Well, in food and beverage processing and pharmaceuticals manufacturing keeping equipment clean is essential. Cross-contamination among batches causes problems, and food or beverage residue can grow harmful microorganisms. Many plants have clean in place (CIP) systems that deliver cleaning tailored to the needs of the facility including cleaning action (force, turbulence, direction), timing/duration (when, how often, how long), temperature, and type/strength of cleaning agent.
When you design equipment for these industries you need to keep cleanability in mind. Even components like electric linear actuators must stand up to cleaning procedures.
When you’re designing equipment, you'll probably be asked, “How long will this machine last?” And even if you’re not asked outright, you know service life is an essential consideration. It’s a critical factor you consider when sourcing components.
Electric linear actuators are important components in many machines, and the “how long will it last” question is a familiar one. If it’s a ball or roller screw actuator, you can use a formula to help estimate life based on load – the same formula used to estimate bearing life.
Industrial automation counts on the reliable motion control that linear actuators provide. Lately, electric linear actuators have gotten more popular because they offer better control of variables like speed, acceleration, position and force than pneumatic or hydraulic cylinders. Electric actuators also offer superior accuracy and repeatability, as well as programmable control that can handle even complex motion profiles. In many applications, they can do all this at a lower cost of ownership than pneumatic or hydraulic actuators.
When an engineer is developing a machine design, accuracy is often top-of-mind. So is machine cost. But these two considerations can be at odds since the usual scenario is that the higher the accuracy of a device, the higher the cost. This certainly holds true for electric linear actuators and linear motion systems.
