Linear Motors | How do they work? 

I wish i earn enough money to show my support to this best educational channel for engineering... Thank you Lesics❤️

This channel has the best technology explanations on RU-vid.

Love it even though it seems a bit confusing but knowing how it works counts and it's simply made and has low noise and stuff.

Technics CD players used a linear motor to drive the laser assembly which allowed extremely quick tracking. You could jump from track 1 to track 10 in about 1/10 of a second. Phillips used a similar motor that was curved instead of straight rotating around a pivot point. This video only talked about how a linear motor moves, and not how it is controlled to be held in a still position when the motion is stopped. (hint: it's not allowed to just rest.)

In order to change the direction of the movement, you need to switch only 2 phases. The phase change at 4:54 only adds 120 degree phase. It does not change the direction. Apart from that, great video for beginners. Congrats!!

Interesting. This is the first I’ve seen a linear motor. Any equipment I’ve had exposure to used axial stepper motors with a cogged belt drive and track. This seems like a much better design.

These are great for pick and place applications where considerable torque is not required. I am a PLC technician, and I use these often. Easy to setup, and programming is a breeze using Ethernet IP. For higher torque applications, I use servos or steppers. The beauty of linear motors is the minimal amount of moving parts. Servos and steppers require actuators and drive systems (lead screws, belts, chains, etc.), therefore there is more maintenance, and potential failures. It's a balancing act of choice, depending on the application. Really love linear motors though!

Very informative! Most machines that require linear motion use a "linear actuator" to achieve this motion, which has a rotary motor and a screw or belt mechanism to translate rotary motion to linear motion. I think the majority of linear motion uses the "linear actuator" and not the linear motor due to a cheaper upfront cost and ease of control for most applications. Would be cool to get my hands on one of these linear motors to try out.

Radius motors are usually used for high power density applications because a spinning armature or stator preserves momentum.

Ah. This little guy beat me in the electrical engineer test! (Almost make my test fail cause there 4 questions about linear motors) And you explain to me!

Nice idea it describes concretely the the phenomenon inside the linear motor . basic for this technology is the regulating movement central magnetic field generator .to be mentioned,many ways to set such linear movement not only using repultion and attraction electromagnetics theories .

Its was helpful for me..thank you

Great video as always. Axial and lateral loads are very useful as well depending on surface tensions and other factors.

I don't usually comment. Never bought any merch or Memberships, but definitely will become a Lesics member.

concise and clear

Excellent explanation sir Thankyou❤️

As a cnc operator i can say with confidence we do not use linear motors in cnc machines. 😂 There is a stepper motor with high torque and a screw attached.

Thanks for sharing! This video is amazing! 👏👏👏👏👏👏🙏🙏🙏🙏🙏🙏🙏

非常的视频，感谢感谢！

Is very educational very good👍...

Great video. Thanks.

Dear Sir, Your videos are very informative and supporting too much to those who are studying in engineering college or doing job in industry. This is best way to use RU-vid platform. Thanks you very much for informative videos. 🙏🙏🙏

Thank you so much.❤

Excellent presentation

Super video, I just might need some help to understand the direction of the current flows on the winding configuration at 2:04 . Aren't the 3 "positives" sides of the generator on the left of the circuit? Because then for me: Step 1: red = 0, blue=positive and yellow=negative Step 2: red=blue=positive and yellow still negative Step 3: red=positive, blue=0 and yellow still negative Did I misinterpreted something or are the flows directions on the circuit not in concordance with the graph?

Thank you for sharing..

Best explanation

Most useful channel

This is pretty good presentation 💖👍.

Great content, ty.

So Nicely Explained 👌👌👌👌👌👌👌

Thank God I am a Chef. What laws what eddy currents omg that was a scrambled egg in my head.

@4:27 - Doesn't the rapidly changing eddy current field in the aluminum block cause it to heat up?

Thanks for this vdo 🙏🙏🙏🙏🙏

I want to know how modern hydraulic steering system works which is frequently used in construction equipments and heavy vehicles .

0:12 sec in I really liked the rotating stator! ;) A question: - Is there a linear stepper motor? If not how would it work? Like an unrolled stepper motor? I really learn a lot from your lessons 👌

Are linear motors efficient, or do they still waste 80 to 90% of the energy into heat?

Can the rod be held at an arbitrary position within the motion range?

Linear Motor are also used on subway trains in China

Quality content ..

Very Nice Bro! Get Good people!

Excellent team lesics

Thanks

Really great!

it's a good information, but this cnc machine needs, a 3D axes geographic map sensor to move exactly to any point of the projects like inkjet printers.

Wonderfull

أليس من الممكن استخدام فكرة الروافع الهيدروليكية بين موتور صغير وتوربين كبير والاستفادة من فائض الطاقه الكهربائيه

always such good videos!

Best ever explanation with animation 😍

Thanks Lesic

But a CNC machine must also maintain a fixed position under load, how does it accomplish that if there is no torque at rest?

Nice ❤❤ Excellent audience 👏👍👌 🥰🥰🥰

Great video.

Cool, thanks.

Thanks👍

So this linear motor seems to work with a track can work without a track? Can it move a vehicle down the road?

This was good, but unfortunately how the windings are arranged in the final thing was wrapped up in about half a second! Are there any diagrams etc that would show how to make one (assuming I have a 3-phase supply)?

Brother, make a video about the sound proof room. How many ways can a room be made? How does this room work? What technology should do it This room? Etc. with information.

Why the shaft is not getting extremaly hot? Is the shaft working also, as a electromagnet?

Is this linear motor suitable for making two legged robot? Robots are mostly built with servo motors today.

Anyone studying the basics of Traveling Wave Induction heater---The first place to come is this video

So, is 3-phase power and switching the ONLY way to control directional changes with linear motors or is it just the most desirable because of 3-phase efficiency?

Thankyou Lesics, you prove that teaching science is an art.

Nice........I would also like to make educational videos like this..So please tell me which editing software should I use....

so in order to change the direction of the moment, always we have to change the terminals......is this done manually or automatically

It is my understanding that aluminum will conduct electrical power but is not attracted by magnetics. Now if the block and rods were a specific carbon steel composition, I can see this working and be able to be tweaked based on mag field strength and the steel rod composition.

This channel is haven for Engineers

Please make a video on PLC and SCADA in electrical engineering🙏🙏🙏

Are signals 90 degree 135 deg and 135 deg spaced out?

Please make machine operation series?🙏

I am learning more from this channel than I did from 4 years expensive university.

Please make videos on the charging station.

Nice

Great video, but i don't understand why at 1:40 the current has the same direction in the blue and yellow coils although the blue phase is positive and the yellow phase is negative

What's the software which is used to make this video? Thank you.

I'm like the dude at 3:14 😮

If linear motor at front or back of bicycle like a jump support, or front or back of skateboard for the same reason?

Pls make a video on servo amplifier working. Your videos are fully understandable for me. Keep this working ☺️

I am seeing and thinking why i found this explanation in late and also thinking about Japan railway technology..

Great channel great explanation. It's just awesome.

can you make a video on washing machines especially manual ones

Hello. How the animation like those in the video made?

Is it possible to make single Phase linear motor?

Could you tell me the name of software can made those video.

Can you please make a Vedio on how SSD works

Việt Nam numbers one

Can you do a video on how an image dissector works for a television tube & LCD television?

Sir can you make a video on how camera works

How can I learn to use the software you use for this videos?

Why we combine this technique to Tesla turbine model to create high torque motor.

What no mention of Prof Eric Braithwaite? Damn spellchecker i meant Laithwaite

I work in company that makes CNC machines with linear motors

I'm pretty sure CNC machines uses stepper motors, because they need precise positioning. At least vinyl cutters certainly do use them.

Insane Clow Posse was right when they said that magnets were miracles.

Por favor pasen este video a Lecis Española, gracias!!!

I am not engineer but i'm interesting in mechanical and would you like to recommend how should i study to become a engineer especially in oversea

💡

cool danke

No wear and tear 😂… only as long as it works in a perfect clean environment and I feel like most CNC machines do not fall into that category

A railgun is also a linear motor
