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 UKposts.

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.)

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.

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

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!!

Excellent explanation sir Thankyou❤️

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.

concise and clear

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.

Its was helpful for me..thank you

Awesome explained

Excellent presentation

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

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 .

Thank you for sharing..

非常的视频，感谢感谢！

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

Thank you so much.❤

This is pretty good presentation 💖👍.

Grat video with great explanations! But I think you should've also said that this is a linear induction motor (LIM) because it works with induction and that there's also another method of building a linear motor: the linear synchronous motor (LSM). This type of motor uses a different method, it has permanent magnets on the secondary (the moving part of the motor) and those magnets are attracted and repelled by the magnetic fields of the primary (the non-moving part of the motor). This LSM concept has some important advantages to the LIM: it's way more efficient (uses way less power and produces less heat), it can go to a specific position way more accurately, in case of an E-Stop the coils can be shorted and the LSM acts as a brake (LIMs can't do this), and lastly, it can achieve way bigger accelerations, speeds and forces than the LIM.

Best explanation

always such good videos!

Great content, ty.

Great video. Thanks.

So Nicely Explained 👌👌👌👌👌👌👌

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

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!

Quality content ..

Really great!

Most useful channel

Thanks for this vdo 🙏🙏🙏🙏🙏

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 UKposts platform. Thanks you very much for informative videos. 🙏🙏🙏

Great video.

Is very educational very good👍...

Excellent team lesics

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.

Nice ❤❤ Excellent audience 👏👍👌 🥰🥰🥰

Very Nice Bro! Get Good people!

Thanks👍

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

Cool, thanks.

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.

Best ever explanation with animation 😍

great. ❤️👌

Linear Motor are also used on subway trains in China

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

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

Can you make a video on how oxygen is produced in factories.

Thanks Lesic

Wonderfull

Please make machine operation series?🙏

Nice video

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

Thanks for uploading this video i am a electrical engineer this video definitely give some knowledge to me

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 👌

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

Thanks

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

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

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

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

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

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

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

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.

This channel is haven for Engineers

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

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.

Nice

Best man best

Keep up the good work guys

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

Can you please make a Vedio on how SSD works

Great video as honey:-)

Sir can you make a video on how camera works

Excellent video! But is it possible a two or just one phase coils building? I’ll google it..

Please make videos on the charging station.

I always assumed it was just a rotary motor gearing configuration.

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

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

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

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)?

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

nice

Hello, Is not a good idea to make the linear movement circular and have a sort of electrical rotational engine...??

What differs a solenoid from a linear motor

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

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

I love your Videos!!! Please create video on how MRI's work :)

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

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?

cool danke

Hmm. CNC motors must be pretty interesting with a lot of strength and acceleration/deceleration of heavy parts with 0,001mm precision despite long travel distances and the environment without controlled temperature, so I expected threaded rods with a stepper motor and some sensors reading accurate position. Actually, it's quite an interesting topic to cover. And by the way piezoelectric linear motors are interesting too.

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

Nice! However for CNC router, only the best had linear motor. The standard one uses step motor.

Wooooow

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
