Two things. Toroidal transformers are better at constraining stray magnetic flux which can induce noise on surrounding electronic circuits which is why they are commonly used in power supplies of professional audio equipment.
If instead of a 50 turn tap on the primary, you instead have two 50 turn coils, you can then have a transformer for both 110v and 220v. Put the coils in series and it becomes 100 turns. Put the coils in parallel and it remains a 50 turn coil with twice the magnetic flux. You see this trick used extensively in older transformer based power supplies.

Manufacturer and designer of toroidal turns tester 3500 A B or C. There still in service today 36 yrs after later. There are times the exact count of turns is critical. I did enjoy the video, nicely done!

Great video. One of the machines I work on uses one leg of 3 phase 208 on the primary side to produce one output of 120v and a second output of 60 volts from a toroidal transformer. I understand it much better now.

It only took 2 months scouring the internet and YouTube, but I finally found an actual thorough explanation/tutorial. TY!

this reminds me of a gearbox. The fact that different connections can switch between different changes in voltage and current are sort of analogous to how different gear ratios produce different changes in angular velocity and torque

[markhonea]

So pure and natural and correct this design, as Flux lines aren't ever square, but most humming/buzzing/vibrating xfmrs are.

I love being able to absorb this info with such ease. Thank you for the great effort put into the graphics and video over all is awesome. Should be mandatory in school. Can’t wait for this to be reverse engineered into levitation once we figure out the ambient voltage out planet produces

[charanvantijn]

The background music is too much foreground and detracts from an otherwise very informative video. Try it without music, rely on the info you want to get across.

Also you have to bear in mind that the Bolt used to secure the toroidal transformer cannot be shorted with the Lid of the housing ( if metal) the bolt acts like a shorted turn & will cause issues.
A firm i worked for yrs ago had this problem when we screwed the lid on the power supply & it just touched the securing bolt & created a dead short.

Thank you for the description and especially for showing respect for Nikola Tesla at the end, the greatest discoverer and inventor that walked this earth.

Very nice, clear, illustrated, understandable video, a trillion thanks

[kazuza]

Thank you, I learned so much from this video

i love the way of your explation and the animation

[mubarakkhan-jwfr]

Video is very informative and useful.Thanks

A steel toroid could be made by casting 2 halves, and then heating them again, and pressing them together, with a little extra steel on the edge, if you counter rotate while pressing them hot, they should be forced into the mold, and together, into one piece.

You'd need openings at the edge of the mold, so the extra steel filings can come out.

Also, 1 hole would need to be left in each half, so that pressure won't collapse or explode the toroid as it heats or cools.

Then, drill and cut out all mounts, drill holes, etc.. and one final annealing to make sure it's one piece, along with other steel components, to be included in the device.

Nice to see how these work. I replace a lot of them on the refrigeration system's we have at work ( Pfannenberg ).

[tedliu]

Thank you for making such a useful video.

[DjTatty]

This is an amazing video, due to the fact you leave out the myth of electrons, and only mention fields which is all there is, at last somebody who knows what there on about, without talking about things that don't exist…….i.e electrons

[niryashk]

A great channel for learning engineering stuff 👍👍

[soonmanlee]

This is so good, very practical, thank you!
