The sales guy keeps telling me this and then trying to charge me $7200 for a $480 motor.
Biggest problem is the price...
Factors for this are:
-Rare earth materials for n52 magnets
-Expensive ASIC controllers for the motor drive
If those would be more cheap i am sure everyone would change... Make it much more affordable, then even home 3d printers can use it.
single nema23 stepper with magnetic encoder and controller == 70$
same size linear electric motor with controller and encoder == 1300$
Not worth it until the price comes down drastically like -95%
exactly i was to say.
I was looking for linear motors few time ago before pandemic for 3D print and airsoft guns. but encoder are bulky and expensive.
@@slevinshafel9395 I agree with both comments here.
I did over a decade of this type of automation before going over in to mining and resources almost 20 years ago and not much has changed at all in those 20 years. Mining doesn't change much either and the reason is simple - the fundamental tasks haven't changed that much.
Doing things like putting caps on containers is the same basic task today as it was decades ago. Pick and place hasn't changed. Its still pick and place. Although the fully variable gripper they show is pretty cool.
The only place I ever saw these was on a flat bed laser cutter. What made it practical was that laser cutter had a monstrously powerful laser. In normal cutting, milling grinding you can't remove metal any faster unless you have a more power in the cutter.
Unless you were doing exquisitely accurate 3D printing or doing 2D laser etching at seriously high speed I can't see these taking over from steppers with lead screws for low resolution or servos with ball screws for higher resolution.
The hardest thing they'll find is the rare earth magnets because that market has a serious undersupply even without the move to EVs. That's where I have had some eye openers in the mining game. things like iron and coal are fairly simple. Dig it up and crush it. Other things like copper, nickel, uranium, aluminum get way more complex very quickly but rare earths are pain in the ass to refine - ask the Malaysians.
You're comparing a linear servo motor to a stepper motor and encoder? It's application dependent. Of course these are going to cost much more. They'll also blow away most other types of actuators in speed and precision.
@@adisharr The point for any engineer is the specs. Do you you need the speed or the precision?
If you don't a stepper might do.
If you do maybe its the solution you need.
@adlisharr is absolutely right. These are indeed different technologies with very different capabilities.
LinMot P01 linear motors are permanently actuated ironless synchronous servo motors with integrated position measurement and over-load protection. Unlike conventional drive solutions, LinMot solutions do not require any mechanical transmission elements (nor external encoders), which simplifies the design and reduces wear to almost zero, thus minimizing maintenance. This provides added value in terms of flexibility, reliability and productivity (with peak motor velocity up to 7.4m/s).
LinMot motors perform particularly well when it comes to consistency of motion, repeatability, operating noise and energy efficiency. In addition, longer lifetime, better MTBF, a minimal number of standard components, lower installation and changeover costs will make up for a better TCO.
Not all applications are the same and will certainly have different levels of innovation, requirements and budgets, which will inevitably determine the best solution to use.
I toured Ingersoll in Rockford over 20 years ago. They were just finishing a set of HMCs for India. All the slides were linear motor built into the slides. 1000 inch per minute rapid feed rate.
How do these motors compare in terms of force output to equivalent OD (OD not bore because the OD matters for retro-fitting) pneumatic cylinders? Obviously pressure would determine the force for pneumatics, so maybe compare the linmot motors to pneumatic at 60psi, 90psi and 120psi
significantly lower force for the same size
The dimension vs force ration is not always a good way to look at it. These might have a similar power density (speed*force/overall volume) to hydraulics and be considerably faster, while providing less force. The could also be easier to control than pneumatics linear motor.
@@Factao if you're designing from scratch and care more about speed you're right, but if you're retrofitting (they seemed to imply was a near drop-in replacement) I figured you'd be dissappointed. Machines might not have room for a bigger actuator to get the same force required to do their jobs, hence my question.
@@BenRyherd fair point
Whats the force graph for these motors over their full stroke length? Do they have fall off at the ends? Or reasonable the same throughout?
For the most of the stroke, the motor force will remain at its peak level. However, when the slider is inside the stator, there will be a reduction in force. This means that during the extended stroke and at the extremities, the peak force might be slightly decreased. To get a detailed understanding of the force characteristics for each stator/slider configuration, you can refer to the force graph provided in the datasheet of every motor. The force graphs can be found at this link: shop.linmot.com/D/linearmotoren.htm. If you have any further questions, please don't hesitate to reach out to our support team at support@linmot.com.

That was very interesting and informative. I had no idea that there was a class of linear motors that worked in this way. The design is so simple and elegant. It's an electromagnetic solenoid, right?
As soon as I read the term 'electric linear motor', I assumed it was the type that most people are familiar with - very whiny electric motors with a gearbox connected to a linear mechanism. This is just so smooth and sophisticated by comparison, it's advantages are immediately obvious.
I'm going to have a look at your website, but I will say that I'm very interested in motion platforms for dynamic environment simulation, like flight simulators. When I saw your video, the first thing I thought was: how big and powerful can these actuators be? Do you make ones which could support a motion platform like a Stewart platform, with a load of, say 500kg?
Thanks for posting this video.
Thank you for your reply and for sharing your enthusiasm. We welcome you to the fascinating world of LinMot.
Yes, exactly. It is a highly dynamic, electromagnetic direct drive with integrated position sensor which suits for several kinds of applications.
Of course, there are already various customers who have used LinMot linear motors to implement as well simulators of all kinds. Stewart platforms or hexapods are among them as well. Here an example of a small version: czcams.com/video/25gox7Ep9yw/video.html

That sounds actually interesting... Might be something for the Prostesis industry. Especially with their multible axis of freedom. I wonder how good they would run on battery...
The suck part about this is that once it’s running and all is well for 5-10 years then it breaks, shorts, AOG, etc and it becomes very difficult to find a replacement because companies go bankrupt, get sold, move on to newer models and you’ll be left forgotten struggling to find a replacement
This is one of the big challenges i face when trying to construct a production cell
With pneumatic, i generally have 3-4 companies with stable foundations offering nearly identical mounting patterns (2-4 extra holes and some extra tolerances in the design and you can swap with a single hex wrench) and a high likelihood of those companies still offering a replacement 50+ years from now
Very well done. Nice and and calm Description of what it is. Nice voice, too.
Linear motor can work reverse if I have ossilating motion can it generate same electricity..
Fantastic !😊
Excellent
you guys wont believe me but this is how they made the pyramids
I want to believe, but I don't.
"Back in the day, people would mostly produce rotation and then transform it into other motion."
Can you tell me what kind of sensor is used to measure the position of the shaft?
We use a custom sin/cos sensor integrated into the stator which allows us to achieve a repeatability of +-0.05mm without the need for external sensors.
Partially true
Could the internal electronics do the same thing as a hydraulic cylinder? I think replacing hoses and pumps for just wires and either an internal or external source of power would be quite interesting
These will never match the force of a hydraulic cylinder per cost
no
The advantage here is not high power density as in hydraulics but precision positioning,high speed movement. Forces generated through stroke range not covered though.
@@johngould8002 And to eliminate the need for an expensive, maintenance intensive hydraulic system too
It may be more cost efficient in energy but if they keep breaking, a pnu cylander is far cheaper to replace
One of the key strengths of LinMot motors lies in their remarkable reliability, not just in terms of motion precision but also in their exceptional lifecycle, which can extend into the billions of cycles. With proper sizing, our motors are engineered to withstand demanding conditions without experiencing any breakdowns. Moreover, their elegantly simple design ensures fewer components that could potentially fail, further enhancing their overall dependability. You can trust that our motors are built to last and deliver consistent performance, providing you with cost-efficiency in the long run.
Imagine what you could do with these when room temperature superconductors become a reality!?!
Should Check out Nippon Pulse , more than 22 different shaft sizes and lengths up to 15 feet long
Are these essentially linear stepper or servo motors?
They are high quality tubular style linear servo motors. LinMot linear motors are permanently actuated synchronous servo motors, with integrated position measurement and over-load protection. Permanent magnets in the slider (like a rotor) and windings in the stator are used to generate forces, like in a brushless rotary motor. The configuration and different arrangement of the magnets generate the linear motion directly, using electromagnetic force, without mechanical elements that are subject to wear.
Basically yes.
I prefer a system that serves me without electricity and sensitive consumer electronics that are susceptible to damage. By the way, the motor in the video is a mechanical motor, all of its components are mechanical ( except for the consumer PCB chip, of course ). Exaggeration of wear and tear is exaggerated and it is a problem that can be solved ! Such as " protection against overload in this video "
hello，i’m a Graduate student. and now im studying in pmlsm control system. I wonder where the video footage at 0:44 comes from?
Maybe from 0:46 to 0:51

How can I buy these in INDIA (country). Can these be used for continuous Oscillation for a long time. I have an application where I want continuous Oscillation at 2.7 m/s , it will run for 8 hours a day but continuous run will be max 20 min and then rest for 5 min and then again 20 min run, 5 min rest and so on.
It's like a real life version of the minecraft piston
Linear motion stages are incredibly mature technology. Linear motors do not enable any significant new capabilities, certainly not enough to be considered revolutionary or even disruptive.
I agree that linear motors have reached a level of maturity, but that doesn't diminish the significant benefits they offer. While they might not be considered disruptive in the traditional sense, they do play a crucial role in enhancing productivity and enabling greater flexibility in various industries.
Linear motors indeed open up new possibilities for innovation. They provide the capability to monitor and update hundreds of parameters and variables in real-time, enabling process monitoring, predictive maintenance, data collection, and aggregation, among other functionalities. This level of advanced control and precision empowers industries to optimize their operations, improve efficiency, and make data-driven decisions, ultimately leading to more streamlined processes and improved overall performance. So, while linear motors may not be disruptive in the same way as groundbreaking inventions, they do offer a wealth of opportunities to innovate and advance various industrial applications.
@@LinMotEurope You can do all of that with a rotary motor and a linear translation stage, and people do use such devices and have done so for decades or longer.
Over and over again I keep hearing the electric motors are “eco friendly” when they’re not taking into account that the electricity that’s being generated to run these motors is produced by petroleum. 🤦🏼♂️ no matter how efficient your electric system is, the simple fact remains that unless the source of the electricity that you’re using is “eco friendly” non of that eco nonsense matters in the end unless you just don’t understand where it comes from or how it’s even made/generated. Yet another example of stellar marketing.
What is this demonstration at 5:30?
The video shows a steel bolt mounted on the shaft of our PR01 LinearRotary modules finding its way through a Plexiglas maze. All processes are programmed via a servo drive module and can be flexibly adapted.

It showcases the precision and speed of these motors. Able to fly through tight slots at crazy speeds while rotating very fast too. Pretty impressive really.
5:28 i don't think the video does the demo justice at this point
Nice Video but....poor audio 🤷♂
I gave up trying to listen. The narrator needs to enunciate more clearly to be understood.
Checking in on ELMs every few years, they're great, but despite their mechanical simplicity and relative lost cost of materials, they're still crazy expensive compared to more complex linear actuators, I think there's a bit of opportunity for an ELM company to grow some cojones and stop trying to build a niche biz on premium pricing these things (good encoder software you write once is not a competitive advantage... so can anyone else). Unfortunately I think I know the country where innovation like mass scale of ELM for low price will happen....
Somehow, the soft ambient music is drowning out what you're saying.
Price, maintenance, and now something my company has to deal with called Right to Repair. If we have to send this back for repair or purchase any new parts from you it's not happening, we've already had to deal with priced gouged PLC controllers and the nickle and diming the engineers in automation have done for decades.
There's a reason why we're still using 40 year old tech for our automated assembly lines, because we can repair them without being fleeced for $50,000+
We understand your concerns regarding price, maintenance, and the Right to Repair issues you mentioned. At LinMot, we take pride in the reliability and longevity of our motors, which can endure billions of cycles without compromising performance.
Our motors are designed with a simple tubular structure, eliminating the need for complex mechanical transmission components such as gearboxes, timing belts, pulleys, cams, or lead screws. This streamlined design not only ensures smoother and quieter operation but also contributes to reducing maintenance requirements significantly.
We aim to provide solutions that offer long-term value and in providing reliable, sustainable, and economical solutions that align with the needs of our customers.

This title late for at least 10 years...
pneumatic cylinders CAN have mech stops and sensors, but they are costly.
A collar and a reed switch is about as cheap as it gets
how much?
hundred motors (cost (or hundred cylinders and one compressor. calculations needed

I can barely hear you mate
I should call her.
The problem is the software.
With a pneumatic cylinder it’s on/off, in/out dead simple. But with an electric motor you have a ton of controller’s, encoders, shielded cables and so on. The controllers often have hundreds of parameters which increases the commissioning time drastically, because they have to be fine-tuned for every use case! Also, have you ever been in EMV hell?
That's absolutely not true. There is products on the market where the controller requires almost 0 commissionning and in the end the system is almost as dead simple as a pneumatic cylinder as on/out in/out ... but also offers extended capabilties if needed as pushing motion (torque control), intermediate position etc ...
And as the drive is integrated to the motor, there is no need for shielded cable, etc ...
@@Difool80 No need of a shielded cable? Have you ever heard of harmonics? More specifically third harmonics? With that many DC components in a factory, you have to rebuild the entire wiring net for it not to mess up. Just like frequency converters does, which need special wiring for it to not create overvoltage on other machines down the line.
No, this system is the entirely opposite of dead simple as a pneumatic cylinder. Also for a pushing motion, these linear rails can't even get close to the power of a pneumatic piston.
I worked in a flour mill for 9 months as a service and repair man. The entire factory runs on pneumatic pistons, the only electric motors are for transport belts and pallet stacking, where they use pneumatic to lift the packs of flour.
@@rasmus1600 I would suggest you to read again my message as I'm not talking about the products presented in this video.
Drives integrated to the motor doesn't require - by nature - any cable between drive and motor. The power cable is as simple M12 4 wires cables, not shielded.
Again : electric axes as simple as pneumatic cylinders does exists on the market. That's the whole point you missed.
Most of the controller software these days is pretty easy to configure. If you're still using systems that require manual tuning then it's most likely pretty old.
3:32 the word is "precision", not "preciseness".
Bin around for 35 years.
Couldn't you DIY your own linear motor? Not as good as this one, but good enough to improve a 3D printer.
Yeah, making any motor isn’t black magic proprietary thing at all, motor design and analysis and construction is so well documented. So many books on it!

4:44 normally without a microprocessor air cylinders only do all in or all out but not if you add a microprocessor to it. My air cylinders use a servo controller so I got as many stopping points as a rc servo controller has, just replace the DC motor with 2 relays with diodes so if the servo controller wants to go left make it trigger the left relay and same for the right and connect each relay to a pair of solenoid valves it works with air or hydraulic depending on how much power you need. But air can be useful for robots to use multiple power supplies it's easy to power a relay and a servo but hard to run the motor so you can use air and use chemistry to make some gas pressure like acid and let the robot eats trash to power the air cylinders. With solar for the low power microprocessors and you can have a robot powered by solar and trash.
easy there cowboy
@@chronokoks you're just jealous because scott figured out how to put a microcontroller into their air cylinder, meanwhile you're still struggling to put a single transistor in yours

The narration leaves much to be desired. The narrator's voice keeps trailing off at the end of sentences, often leaving the last words of the sentence unclear.
Dude, WTF? Nobody spoke up about this? Wow.
Pneumatics could be just as accurate with the same feedback as the electric unit. This video is really boring as well.
Typical CZcams drivel, the title is linear motors, then painstakingly describes what the downtime is. Hello, stop wasting our time!!!!!!!
What is the point of all this if I can't afford to pay for a goddamn house? I don't care if the price is reduced to 1% of what it used to be. You know why? BECAUSE I'M JOBLESS.
funny
automation like this helps with the labor market, because it helps end international trade, because it becomes cheaper to make them where the products are sold then shipping across the globe. so more manufacturing locations means more local jobs, shipping is screwed but like 10 people drive one of these big cargo ships. so it will be a net gain in jobs. also house prices has everything to do with it being tied to the money and the banking system, if houses were their actual price we would see some people buying houses in unpopular areas to harvest and then sell the materials. their is no such thing as a labor shortage you just have to pay them more $$$$$, people will work on remote oil rig it does not matter where it is.
