Called out to work again? :o .. Omnibus, will get back to you ...soon as I get back... with my ideas.

(1)? (1/2) ring magnet (rotor)
(2) The "Cap" or "Descenso Controlado" is 1/2 Diameter also, and allows only 1 arm up fully and 1 arm STARTING up ... the Arms are positioned BELOW the "invisible Mid-Line" of the rotor? (as I was talking about in beggining) which repels AND keeps them in a DOWN position...only the Rolling Magnet Wheel pushes the Arms UP...the Cap pushes only CONTROLS or makes sure of the timing... once the rotor half is past, the arms fall on their own, perhaps even pushing (or adding) to the total push of the system.
(3) Stator magnets on my replication will not be beveled, but it would probably help
(4) The "area" or spot of the cap that allows for the arms lifted part will only be same area as 2 X (times) the width of whatever sized magnets you use for the stators.


Note: the ANGLE of the stator Arms is very important...so is the fulcrum distance...I believe we are after "Shearing" forces, laterally: Right Angle Shear

Anyway, will be back tonite with drawings...

Til later,

JayBird

Quoting Lynxis, from another thread:
Quote
Seems the simple "tidder todder" device being shown in various documents would
be the very easiest to attempt understanding and building"...

and if It can be proven to work... then one could develop this further to
produce motive force to drive a wheel.

There are some experimental setups that one should probably do as described
to understand the priniciples -- and then on to the perpetual version of that
tidder todder. (which is my nickname for that contraption)...
But that darn tidder-todder (if it can be made to work) // would actually be a form
of perpetual-pendulum...

 The Gary Magnet motor is what I WAS replicating when I came across this very thread...I believe the same forces are in play here, or are very related... I guess time will tell.

 And , I am still going to finish my Gary rep also...

PS: Keep up the GREAT work Tao! and thank yous go out to everyone working on this, and Stefan also for the bandwidth and website...

@tao
Many thanks for the new video. Looks nice !
This is better now, but one can not see, why the stators
are lifted.
Maybe you can also render the same movie with a top view,
so one can see it from above ?

But maybe it is still better, when you use for the
lipcap a tranparent surface mapping, so one could
see through it ?
Also it would be good, if you would maybe advance the
timing by 10 deegrees, so the stators go up a bit before the
north-south-zonechange of the rotor disc magnet ?
Many thanks.

@Tao,
here is the first video from you converted to a smaller file and screen size
to play smoothly also  on older slower  PCs.

ok my first replication failed!

warning remember to create a prototype that you can adjust! don't use glue to hold your elevating arms or rotor magnets down. create a system for adjustment on each.

my problem is not the design but in the manufacturing. as follows:

I placed my elevating arms to far from the rotor and got no reaction from the rotor
i placed the rotor magnets to close to the "weel arm?" (<---- needs a name)

a track drilled through the rotor (in this case i used a hard drive disk) to allow the magnet to be attached and adjusted would have helped. simply attach a bead of epoxy to the bottom of the magnet trim to fit in track and dril small hole in epoxy. use a screw (into the epoxy hole) and tighten down to disk.

same for the arms. drill track into base so that a screw from the bottom into the elevating arm can tighten and loosen the arm allowing adjustment.

i strongly recomend this in all your prototypes! i will have to break my magnets free now and start all over! do not get to hasty as i did, this is how mistakes are made :) duh! :) .

thanks
danny

great job tao and hartiberlin ! those are great animations. :) thank you! I am working on a presentation wich i will pass through a few of you. this presentation will be simple instructions of how, why, and what, as well as how to with this device. i will be leaving it in simple terms for those of us who went to the local technical callage instead of harvard! i will leave the figures and numbers for the rest of you to present :) . I am saying this because i will be using all these graphics in my presentation. if you have any objection to this please let me know so i can abbide by your wishes. I am not one to steal ones hard work! :) thanks

Thanks, Stefan. That?s really great. Of course, thanks again, tao.

Now on more practical side, how exactly did you calculate the torque with the FEMM? How do you choose the contour to integrate? Take, for instance, tao?s schematic magmotor18.ans. What I do is first choose to operate on segments and then click clockwise on the four nodes of the rotor. Thus, I obtain ?7.51314 N m, for the torque from the stress tensor. Is this the value you get as well?

let me know how your protype goes. I do not agree with your theory (just cause it directly conflicts with mine :) ?) but that does not mean your wrong .

I believe that there is a lot of upwards pressure on the stator magnets. ill explain.

the down stator magnets must be directly even with the rotor magnet to work (angled should be fine but not below the midline) the up stator magnet must rise above the rotor magnet and at least mostly out of the magnetic feild of the rotor magnet(s). the magnetic field of the stator magnets to the sides push against the magnets between them. since it can not move down (do to the base being there) to get out of the way it will attempt to move up. this is where the cap comes in holding it down untill it is it's turn to move up. not only are the magnets to the side of each magnet applying inword pressure on each magnet but the rotor magnet is also aplying pressure as well. if the stator magnet were angled downwards then the forces all around it would slow the rotor and decrease over all power to the device. this is due to the downward pressure created by the rotor magnet being above the end of the stator magnet and side magnets pressuring against the sides as the weel of the rotor attemptes to raise it. the over all performance would also be effected by the difficulty that the rotor cap would have in pushing the stator magnet down past the rotor magnet level. also by using only half of a disk magnet (not sure of this) but arent you setting the rotor off balance (in terms of weight)? and also if you cut a magnet in half dont the poles re adjust? (image provided)

in short the arms will have to pass the midline of the rotor magnets wich if the rotor has to do this it will drag the rpms and torque down dramatically.
not to mention getting them down again will not happen without force. the arms will not just fall down past the rotors midline...

if the north end of the stator magnets is below the north end of the rotor magnet then you are robbing the device of efficiency. the point of strongest repulsion/attraction is at the midline. not only would the stator magnets be below the midline of the rotor but the top of the magnet would be the surface interacting with the rotor (pushing up)

in torbays original weel design i think the weels job is not to lift the stator magnet, but simply to knock it out of the feild. the slightest nudge should give the feild all it needs. the inward pressure of all the surrounding magnets should push it the rest of the way up. ?the cap brings it down to just the right level so as not to push it below the magnetic curve of the rotor magnet.

i think that the magnet polarised through its diameter (in full) will help releave a lot of the pressure on the rotor cap. thus allowing it to produce more rpms and torque.

i may (and probably am) missunderstanding just what you intend. perhaps you can explain your theory in more depth.

if i have gotten your plan wrong i am sorry.

silverdragonrs, which one of the constructions are you replicating? Is it the one with the bevels or that with the springs? Can you post a video, even if the motor isn?t working, or at least a photo of your motor?

off topic....

perhaps you could rar/zip (winrar has an option to save as zip) your avi files to increase download/upload times and save some more bandwidth as well :) just an idea :)

sorry omnibus my camera is a peice of junk and wont work anymore. and i have no video camera. i did post a mspaint layout of what i was doing earlier. take a look at that.

thanks danny

when and if i get a working replica going i will borrow a digital video camera off my mother inlaw so you do not have to take my word on it. just thaught i would add that. :)

danny

p.s. (call me danny, silverdragonrs is to much to type! :) )
