magnet-gravity wheel

use brakes? 

also make it a one-way wheel

Well, I'm back. After running into some conclusions with my work I took some time off. So I'm back to share what I have found. I'll probably post my research and theories again in the next month or so. As for this problem. I would like to lend a hand. I just have a few questions to ask. Just so you know where I am coming from my current view is that this will not work. But I guess now its my job to prove my theory. So the questions I have are from the last picture:

Is the wheel rotating clockwise?

Is the magnet at the end of arm A being repelled from the SMOT? Same poles?

Where is the center of mass(balance) for each arm? At the center of the arm or at the end where the magnet is?


Here are a few links to information of physics and how to analyse a wheel. They are a good toolbox of knowledge.

hope this new picture explains it all. (must be logged in to see picture )

the smot must only be strong enough to pick up the weight of arm A. must be adjusted accordingly.

at the sticky point you will have twice (arm C and D) the weight going against the sticky point.

ummmm I like this one and reckon I have got all the bits to actually knock it up within a couple of hours, so might try it out the weekend when back home and let you know what the results are.

The Mini Linear rails I have travel about 1.5", so I reckon If I mill the square out to 2" then give it a whirl.

Will post results as usual when it is done.

Regards

Sean.

The SMOT will no doubt pick up arm A, but magnets don't usually let go. Tuning the other forces to overcome the "sticky spot" seems to be the problem in these designs. Maybe when the force from arm D on the wheel increase arm A should be at the sticky spot.
