Magnet Motor from Argentina, part2

[Craigy]

Hi Mrd and everyone,

i hope to be at the stage where i can post a video of my motor doing the basic rotor movement this weekend. i am torn between mrd's magnet push up and torbays cam off the rotor. But i think i will worry about that when i find out if my effort will chase the gap or not.
You mentioned that the gaps between stators appears large, and perhaps you are right. I'm using what i have lying around and the stator magnets although 15mm in diameter are all i have at the mo, Regardless if it passes the first test of not i will post a video. We are all here to learn and my mistakes might help avoid someone from doing the same thing.
( one reason for using this type of magnet is that they make nice wheels, i thought that perhaps i could kill 2 birds with one stone and have them go down the ramp....)

I have also been thinking about the unbalanced rotor, with that in mind i weighed all of the hardware on the rotor, i have 156 grams to put on the other side, not sure what to use for balast tho.

Keep the ideas coming, between us all we will crack it

Cheers

Hi Craig,

Your doing well, youve made the leap to give it ago, thats worth more than anything.
I'm observing things with my setup, if i move one stator magnet out of line, the rotor magnet will not be in the right position, to be flipped.
Keep at it matey, don't be discouraged if at first you don't get the results you expect, technology came to us through persistence and by accident.

What i'm trying to do is learn from how this thing should work, Walter is definitely onto something.
I was thinking of the top disc, i'm probably wrong regarding weights, if you ramp it correctly, the stator magnets just behind, will have nowhere to go, but forward.

I'm going to try the aluminium runner around the circumference, as i have the wheels setup that way, if this doesnt do it, then im going to try magnets on the back of the leavers, and lastly the top disc, whichever works best...lol
Take your time, take breaks and be patient.

Rgds,

Hi Craig,

I've narrowed down that, Top disk and magnets are the way to go, I've tried the aluminium on the side rollers but it's not good, too much friction.
I will keep you posted when i have it finished.

Cheers,

Hi Mrd,

Well it works! Although i noticed a few things,

in my design i have used small 1/4 inch x 1/2 inch magnets that i mounted inside of brass terminal block so that i cound add or remove as required. Since i found that a half circle of magnets , one every 15 degrees 13 magnets did not work as well as just 11 magnets.

One of the problems with this approch is that the rotor has 11 magnets or 11 magnetic bubbles or Fields. these can cause the rotor to stick if the stators fall between these fields. The best solution there fore would be one magnet with one field so that the stator in line to be lifted is on the edge of the rotors field. This perhaps is only a problem when starting up, since on my model the rotor may sometimes come to rest too late, i.e it has a magnet go past the stator. When we lift that magnet the rotor moves to equlibrum which is not always in the direction required. It is easy to fix on my model i think i will just need stators that have a wider magnetic field so jaming cannot occur.

Well i have been trying to post my video for 2 days now but the server is always ropey, anyway i have changed the angles of all of the rotor magnets so that their faces point backwards to the direction of rotation( Like magnetic wankel ) and there is a marked improvement, and no jamming.
