I have received the neomagnets already.
400pcs 20mm long, 5mm in diameter.
Finally some build can begin  :)

I also ordered a lot of 100mm x 20mm x 5mm Y30 ferrite magnets. Ferrites are weaker than neos, but much cheaper, and a 100 x 20 x 5 can hold approx 4kg iron piece if kept flushed with the magnet. I will use them as stator magnet. Placing them side by side to create one 180° arch with N/S, inner/outer radius, and one opposite S/N inner/outer radius.
A link to the magnets I bought 4 lots of (40 pcs in total).

Here is a simplified explanation on how magnetic timing can enhance torque.
The figure explains that timing is related to how many degrees the brushes in an electric DC motor is turned 45° in the same direction as the rotor is going.
The round magnets is supposed to be electromagnets. Commutators are not shown, but the magnetic polarity is shown.


In my design, however, I use a belt with lots of magnets. One half has South outwards, and the other half has North outwards. This is how and why an electric DC motor work.
It is only the magnetic field that rotates, and not the physical magnets. More precise; the physical rotormagnets moves perpendicular to rotation and across the magnetic field instead of along with it.
This is possible because the belt with all the magnets winds along and between the pulleys clockwise in the same speed as the pulleys moves counterclockwise.


This design will become more clear when I have built it - and it will also become more clear how the mechanics is supposed to work.

Refering to the figure above, with the white arrows:
The white arrows is responsible for some of the torque, but not all. It is responsible for approx 1/3 of the torque.
What is done when the belt/chain is held back so it can wind itself "backwards" as illustrated in the second figure above, is that all the contribution of this force is lost.
However, the torque around the magnets will still be there, and not affected by this. Since the torque in the magnets is approx 60% greater, I have a positive result.


If we imagine that the motor is laying flat, horizontally:
The next obstacle might be where the pole on the belt change direction, and how that magnetic field oppose the field from the statormagnet as it winds backwards and enter and exits the vertical statorfield.
I think that, if the statormagnet is wider than the rotor, the vertical field gets weaker. Still, the horizontal field, that accounts for the torque in the rotormagnets, will not get weaker, but more and more parallell to the rotorfield as the statormagnet is wider (taller, if we look at a laying statormagnet).
The horizontal statorfield has a gradient. This gradient is responsible for the torque.

Printed out two main rotors. Now printing 24 pcs spokes.
Next is 24 pcs pulleys.
You can see one spoke and pulley attached to one of the main rotors.
The other image shows red end caps, green belt part.
Last picture is a small assambly of two magnets, belt part, and the end cap for the magnets. 288 pcs of each will be printed too. All white plastic...

Finished all 144 belt links and 288 magnet-endcaps. Printing 24x pulleys now - 7 hours remaining...


Finally, some gears attaced to 12 of the pulleys, and a circular gear track. These gears will wind the belt "backwards" into fixed position as the wave shape and magnetig field is rotating.
Looks good this far :)

Testrunning a small belt. All magnets with same direction, across the belt.
This belt feels like a soft stress ball. Low friction.
Tested it on one pulley attached to the drilling machine. Looks smooth, except the belt jumped off and escaped towards the steel on the chuck.

Starting to get some shape now.
These rotors are turned 15° from eachother.
I will finish the magnetic belt, but before that I'll put a 34mm spacer on the rod to keep perfect distance between the wheels so the number of links in the belt adds up with as little tension as possible. A quick test shows very little friction, but who cares. If this works, friction is not a problem...

Still waiting for a bunch of ferrite magnets to arrive. Those will be stator magnets. I'm afraid they're not long enough. 100mm long, and the width of the complete wheel, including belt, is approx 80mm. Rotor diameter is approx 225mm.

Assembling a belt is time consuming. Not even finished 50% of it after 3 hours work. Every link need tweaking... :o

Hi Vidar,


I can't believe no one has commented since you started showing your building progress, which is awesome by the way and so is your design.


I'm sure everyone is looking forward in seeing the results of this most interesting idea.


I assume you have to tune each link because of small printing imperfections?


Thanks for sharing


Regards
Luc

Well Luc,i cant believe i missed this project either.
What a huge project.

Will be keeping an eye on this one for sure.

Good job Vidar  ;)

Thaks Luc and Brad!


Yes, I think it is an interesting design. I posted a less detailed idea on an alternative energy source website a while ago. Engineers and inventors had never seen this idea before. Funny to know that no one, or at least possibly very few people has ever thinked about this approach before. They hadn't seen this before, or even thinked about anything similar :)


I have been struggeling with tweaking, when I finally realized that the printer nozzle is 0.4, not 0.5...
I must start over with all pulleys, links, and end caps. Did some improvements in the design so it doesn't jump off so easily. Every part of the belt is internally repelling. This force the belt radially to jump off the pulleys (which has too small teeth).
Narrower pulley, longer teeths,and wider end caps will secure the belt and the magnets much better.


The temp sensor sometimes glitches, so filament got burned. Replaced the nozzle three times just today...


I'll keep going anyways :)

Printing gears for the pulleys. These will follow a large gear so the belt can keep its polarity still.

New better parts on its way. This will secure the belt much better, and makes it possible to put glue into the endcaps to secure the magnets.
