This is probably one of the best videos I have ever seen! Great Work Dude! Really Appreciable, So Impressive!

[@deadeyejones6403]

This is....The coolest project....I've ever seen. Keep up the good work!

[@felipepadulasanches6865]

Wow, the amount of work you must had to make this video is astounding! Great work

[@EngineeringSpareTime]

Thank you! Yes, that was a bit of work. Fortunately, the planning and manufacturing went quite well. I didn't have to re-work the PCBs, which saved a lot of time :)

[@sirmaxx7639]

Amazing. Insane amount of work done. Great design.

[@thombaz]

Cooling with fans in vacuum? :D Really amazing work, the way you put in so much work to such a 'small' project is really inpiring.

Really great video👍 I want to build my own maglev like the transrapid. My question is wich sensor did you use for the levitation?

[@max_eley]

Truly amazing stuff, thanks for sharing.

[@maxhouseman3129]

Very nice work! Clean design, especially the PCB and wiring. I guess you are doing hardware engineering for living? Greets from a hw-engineer.

[@EngineeringSpareTime]

Thanks - I appreciate it! I don't do it for a living yet (at least not at the moment..), but have been doing it with passion for a long time. I have studied mechanical engineering and am now studying Robotics.

incredible

[@graealex]

While Hyperloop is as practical as an Ekranoplan, this is some impressive engineering.

[@EngineeringSpareTime]

Thanks! The Ekranoplan is impressive :) Practicality definitely depends on the technology used. This must evolve to enable a deployable system.

[@Thorhian]

Would higher and higher temperature super conductors make trains like this more viable?

[@EngineeringSpareTime]

@@Thorhian This is certainly a core of the research. The cooling effort for the systems used today, for example, in the chinese Maglev is very high, which makes the system complex and cost-intensive. A particular question, in my opinion, is the availability of the materials used for this purpose in large scale..

[@graealex]

@@Thorhian The problem with Hyperloop is the vacuum tube, not the magnetic levitation. Maglev works fine, SCMaglev has shown speeds of 600 km/h, although it's simply very costly to build a track. For example, the (conventional) Beijing-Shanghai high-speed railway reaches 380 km/h and cost $20m to build per km, including a lot of viaducts and tunnels, while the Shanghai maglev train runs at up to 430 km/h, with $40m building cost per km, with no real obstacles in terrain.

[@EngineeringSpareTime]

That’s correct. A big part of the track cost is also driven by the propulsion and levitation technology used - this is what I mentioned earlier. The track for the Shanghai maglev for example features passiv coils on all sides.. this has to be expensive. In terms of the hyperloop, there are additional costs for the vacuum tube obviously, what doesn’t do the concept a favor in the first place, it reduces the energy use a lot though. E.g active levitation in the pod reduces the track cost. Propulsion is still a thing.. it’s hard to beat a “decentral” drive system like a conventional train in terms of track cost. On the other hand e.g. a long stator linear motor in the track increases the track cost a lot, reduces the vehicle cost and complexity though..

What a high efford

[@passionatechristianmaker]

bro i gotta try this out

[@saveplanet3977]

Truly amazing

[@Thorhian]

Awesome stuff dude! I clicked almost immediately when you pupped up in my sub-box. I do have a question though. I want to learn how to make my own motors, both linear and the more normal rotational ones. Do you have any recommendations on how to learn how to do this without going to a university to learn how to do so lol? I'm a computer science student but I do love this stuff as well.

[@SIVARTproductions]

this is a pretty good video on the design and build of a brushless motor kzbin.info/www/bejne/j6S2nmlreaaWeck

[@EngineeringSpareTime]

Thank you! To get to understand the topic, I would first watch/read through various explanatory videos and reports on the subject. It helps especially to look at different designs and setups to develop a feeling and understanding. Once the basic principle is understood and various setups internalized, you can move on to the actual designing - technical literature. To do this, it is definitely good to familiarize yourself with Maxwell's equations in order to be able to understand what is stated there (an understanding of the interrelationships is enough for the beginning). Literature there would be for example: "Electrical Machines and Drives - Fundamentals" - Springer; "Control of Electrical drives" - Springer; There are many books on this subject.... In any case, your question is legitimate, because the start into this topic is not all practical. The textbooks usually assume a lot and are very extensive. Therefore building up previous understanding is essential. I hope this kinda gives an idea :)

[@EngineeringSpareTime]

@digdog Yes, this one is nicely done. Recreating one of those definitely helps to develop an understanding.

[@Thorhian]

@@EngineeringSpareTime it sure does. I’ve looked into some of the basics for 3-phase induction motors and a little bit into brushless DC motors. I have some level of understanding how they work, but I lack the math/physics knowledge on how to actually design something like a standard induction motor or any other one. It also seems like it is hard to get a hold of decent materials for building motors (like electrical steel to get better magnetic flux, usually made of sheets that get sandwiched together and insulated). Milling out that steel for your levitation coils was pretty cool to see though. I love your mini-mill, especially since you made the spindle and tool-changer yourself. I’ll have to “get good” with Maxwell’s equations and the math needed for that I suppose lol.

[@EngineeringSpareTime]

@@Thorhian Yes, that's right. Regarding the design of an electric machine, it's hard to find anything at first. To get in there, the rest definitely needs to be understood first. There are certainly approximations and the possibility of orienting oneself on existing designs - it depends on how far you want to go there. For high requirements, there is no way around a magnetic simulation... Just to clarify, the engine in my video is definitely not optimal. I had to weigh cost, time as well as functionality. This linear motor is a coreless one (no iron core) which comes along with a low permeability and therefore low field strength in the interesting area... Here it had to be considered that the linear motor counteracts the levitation, because this attracts the pod in Z-direction... thus with iron core it would not have worked. Regarding the Material: Yes, I tried to get the proper coated sheet metal for lamination for a different project before - difficult cause its not too common :) There are some chinese suppliers or one could ask a manufacturer directly.

This is awesome! What are those spring loaded electrical contacts on your PCB called?

[@EngineeringSpareTime]

Thanks! :) The ones I used are called: Modular contacts - bourns They can be used with a ready made counterpart or accordingly designed ENIG PCB pads (the option I went with)

Amazing, are the coils attracted to those shiny tubes on the track, what are they made of?

[@EngineeringSpareTime]

Thanks! The coils are attracted to the metal bars attached on the levers along the track. The shiny tubes are just for guidance and made of stainless, so those are not magnetic.

[@peegion4742]

@@EngineeringSpareTime Just came back to this and was wondering what distance sensors you used to get that level of accuracy (like the pod can't move more than a cm, right?)

[@rohamarab9029]

I was wondering can you please say where you got some of the things since I'm doing a hyperloop for my school project and I do not know where to buy the magnets, the PCB, or the big tube for the hyperloop. Do you also know somewhere we can buy magnets for the levitation?

[@EngineeringSpareTime]

Thanks for your comment. As partly shown in the video, most of the parts are manufactured by myself and the tube for example is supplied by a local manufacturer. Thus it is not possible to just purchase and assemble the finished parts.

[@Fairwayforagers]

hey man i just wanted to let you know that you inspired me to do my schülerprojekt the excact same as you thanks for the inspiration and i would be happy to hear an answer on your thought, if i make it a vaccum champer pipe will it be faster, because there is less air resistance? thanks a lot

[@EngineeringSpareTime]

Hey, glad to hear this. In this size the main issue is thermal stability. The less air you have in the tube the less effective will convection cooling be (air cooling). Additionally at such low speeds the air drag, what you want to reduce with the vacuum at higher speeds, doesn’t make to much of a difference. The achievable speed comes down to the design of the linear motor and it’s control. This version is quite slow mainly due to the control algorithm and position sensor been used. Would be great to know how it went for you. Until then best of luck with your project 💪🏼

[@Fairwayforagers]

Thank you sooooo much i might do a version without all the electric stuff but definitely a huge thank you to you and i will comment, once i made it!
