Welcome! This is basically the section of my brain who thinks about everything high speed mobility tech-related written out for you to see. Its constantly updated as i think of new curiosities to deep dive, find new info & news, and build out whatever high-speed ideas come up. So far I’ve looked into optimizing linear induction motors (LIMs) a common motor choice for hyperloops (version 1). Then into building out MVPs of levitating induction coils in a 3 week sprint (version 2). Plus a little detour into hyperloop & high-speed safety (also smushed into version 2), and the in-progress (version 3).

p.s. Click here for a quick/more concise recap on my building Maglev Motors for New Applications

Version 3: Eddy Current brakes

<aside> 🧠

Hypothesis:

• Use the same principles of maglev but instead of levitating & propelling trains, I slow/stop aerospace crafts from around the same speeds </aside>

Reverse Maglev Hub

I ended up building out & simulating the model online and found too many technical problems for me to actually build it out and test it on mini planes. —I also kinda got bored of maglev tech

The goal was to slow down planes during landings by using maglev tech, which reduces friction by levitating, propelling, and stopping trains at super-high speeds without contact. Planes currently use advanced carbon materials that withstand significantly more friction than previous steel brakes, but they still need to be replaced after 350-2,000 landings. This may sound like a lot, but it only applies if they are properly maintained and manufactured (extra $). The consistent problem modern carbon plane brakes still face is that they wear down quickly due to the high friction/heat, demanding frequent repairs. The brake set on a Boeing 777 costs over $100,000 USD. This adds up quickly when there are multiple planes to maintain.

• It's similar to Aeroflux, but a different design with fewer parts & electricity input required

• Aeroflux, JDA- crazy sickk that it works!

Version 2: Levitation & Safety at the highest ground speeds

<aside> 🧠 Hypothesis:

• Hyperloop (maglev in vac tubes) will become a reality faster if the technology is to mature in new environments </aside>

Controlling electromagnets detour

Using arduino to learn how to better control inputs into the coils.

Coil control hub

Safety detour

Took a little detour from motor building too look at the progress of safety, regulations, and certifications in the world of hyperloop

Reinventing safety at 1000+ kph

Hyperloop TT

• Notes & research from interesting ppl I talked to (btw i gotta find notes from them, this is a work in progress)

GOT IT!! Progress of a week of an Arduino learning sprint & learning about transistors.

Final words on the detours This is a group of not fully finished ideas in version 2.

• I had a lot of ideas on how i wanted to go forward next without the time to make them happen nor the interest to see them through
• These were mainly trying to figure out what defines safety at extremely high speeds and how I can control the big sparky levitating outcomes I was getting </aside>

Building LIMs iteration 2.0: What does it take to levitate?

I’ve never actually been able to build linear induction that levitated, so here’s my shot at it. In 3 weeks I got 3 cm in magnetic levitation!!! Huge step up that all my past work since first learning about them October 2023, only leading me to barely a milimetre.

Motor Round 2 → new hub for next 3 weeks (May 5- June 6)

Final thoughts post-building

• Never had this much success and failure in such a short time period before. I had some of the biggest short circuits and also the biggest levitation I'd ever seen.
• This speed definitely undermined safety. The electrical flow and magnetics had no control whatsoever. That was terrifying and that’s what I’m hoping to figure out next </aside>

Version 1: Optimizing Hyperloop Motors

LIMs 1.0

<aside> 🧠 Hypothesis:

• Smarter and More Energy Conscious LIMs Are the 1st Step to Hyperloops & high-speed transit

Main Questions this research answers:

• Could it work if we make circular LIMs to reduce end effects? How much more do polyphases increase LIM efficiency? </aside>
