Luling magnet motor with 3D printed parts (motion only bij permanent magnets)

[Ufopolitics]

Hi Ufo! Yes that's me, I get around between here, OUR and EF. And yes a long time indeed!

I did a quick concept drawing and I can see everything you're saying. This one came up with 16 degrees to go from 0 to 3.5 mm. That could be reduced but not by much.
If I try this it will have to have a flywheel as well as a way to adjust the cam centerline timing, I think.

Remember the way they used to graph steam engine strokes? I can't remember what they called them, but what if you attached a degree paper to your rotor and a pen to your magnet and ran your motor to produce a stroke vs. rotation graph of the magnet. Well, that would be very interesting, but I don't seriously suggest you do that.

Good luck with your motor improvements! A lot of people are watching.

Hello Cadman,


That is great man, I know you are a heck of a builder, one of the best in EF, as Machinealive or Cornboy...!!


About your small cam concept is great, for the "triggering" or Input side, I mean, angles should be kept short and traveling distance also small for the Input...
However, the issue here is that it needs to be "amplified" or increased when it comes to the Magnet Distance retraction...and then 3.5mm is too short travel.


So, one of the ways I believe this can be solved in Mechanical Engineering is by the use of Levers, which also move within short angles.


I have achieved (in CAD up to now) from 2mm as Input of the trigger to 15mm of magnet travel distance (Output).


The second issue here, is the max force that it needs to be applied to separate magnet from the closest gap...However, according to my research and experimenting, the good news is that the MAX Force only needs to be applied for like 2-3mm.


Therefore I have ISOLATED different forces as first, the one to pull away magnet in first stage, around 2mm...then your triggering mechanism and travel longer distance would be easier to move back and forth...then ending with a Retur Spring, also in a separate configuration...


And the effect we are trying to recreate, replicate, achieve, is to be as close to the effect the pneumatic valve and piston generates...except, it will not have any external supply of nothing.




Regards friend!!

Hi Knovos & Ufo,

My main project is on hold due to eternal shipping so I'm making progress with this motor design, and materials for this are now on order. Simple roller cam actuated, snap action, full 15 mm trigger movement within 2 degrees rotation; triggering returns some energy to the rotation.

I don't want to clutter up your thread any further Knovos, so if my build starts to be viable I may ask Ufo for a thread.

Hello Cadman,
Great idea!!
You can go ahead and open a Thread, anytime you please my friend!
It would be great for references about your Diagrams, as it will show the progress...


Warm regards

This is the idea I've developed so far. I'm already building but the spike push mechanism (blue) still needs special attention. The red disk on the turntable is to determine the moment pushing the magnet. This red disc can therefore be turned and secured with a wing nut. Maybe also make a small dash division for the adjustment.


I designed the spiking mechanism open to see how it functions while spinning and to fix any problems. The red turndisk could also get a bearing to reduce friction.

Hello Knovos,


That looks good!!


Now, may I suggest you build your retracting mechanism(s) (Blue) away from where the magnets meet?
And I know you are using mainly plastic, but, Springs, and shafts are steel correct?
All steel surrounding fields, will interfere with the magnetic interactions, deviating field and causing to throw off your neutralization.


You could set blue on a side, or Higher above, then get actuator closer to border of rotor.


However, if you have all stainless steel shafts, nuts, bolts and Springs, meaning, all hardware-fasteners on blue mechanism, then it will not cause any interference and disregard my advice.
