Magnetic Motion Device

E2,

There's little doubt the lenz effect would be a problem if I put the mags too close to the aluminum but a plastic insert of maybe 3" should keep me far enough away to reduce that effect. First build for me will be strictly out of plastic/polycarbonate or something that I can bend and flex. Will watch what happens with DTB first since I'm still having too much fun with bedini type variations where I have two 6" aluminum disks, seperated by roughly 5" and have mounted four oposite pole facing neo's 1/2" tall by 3/4 width cylinder mags with a hole through the center for easy mounting on each disk and 4 wire Litz coils to drive it and play with tapping 1 or 2 of the wires to use as a generator. I believe the guage of each of the four litz wires is either 26 or 28. Anyway, it offers many combinations to play with. Haven't thrown a hall effect into the mix just yet since my tiny trigger coil made out of 40 guage seems to give me an adequately short duration pulse that I can chop, shorten and just plain work with. Only drawback is that darn 40 is so weak I've had to remake several times already but that's for anothere thread.
What might tie that into this is the thought of using DTB's concept on the outer edges of my bedini build as an assist.

@DreamThinkBuild;
Curious, in your test build, if the rotor is placed beyond the first gate and released, does the rotor self accelerate or is the push through the first gate required?

Hi Casman,

Really like your graphic sim, nice work.
Do you have a 3D printer???

Thank you, yes I have Makerbot Replicator 3D printer, took a while to save up for but worth every penny. Slowly paying itself back with repairs around the house and being able to test more complicated models.

I'm going to keep the design completely plastic except for the magnets to avoid any metal at first.

Hi E2Matrix,

I'll try the idea CrazyCut has suggested and do in segments and also putting small holes in the back of each magnet space they can be pushed out and reused if a design fails. Have to find the right curvature to maintain that pattern.

Hi CrazyCut,

You can do a half track test first to minimize work and cost, see if it will run on curve, if it does, then construction of a whole scale will follow...

Thanks, that is a very good idea!
Build just a quarter of the curve and see if it can navigate it. Then add a second quarter, then the last two quarters.

Hi Brad,

When the rotor is first pushed in there is resistance the two poles between rotor and stator are in direct opposition. Once the rotor gets halfway through the first stator magnet it takes off. Another interesting effect is if I put the rotor magnet in the middle of the track and keep the rotor stationary it will push the stator backwards in the opposite direction. So it might be possible to hold the rotor fixed and have the stator rotate around. I attached a picture of where the gating occurs the rotor is shown right where it takes off. It seems like once it gets in that barbed pattern setup by the stator it is squeezed out.

Hi DTB,As i see it,  if there's a magnet beyond that gate it wil push through, so if it is continiously constructed it's possible to run without the sticky point,  well we need to know first if it will go into a curve.... thank you for sharing and effort...   Will wait for your progress...

It is an interesting observation.   I think if both  rotor and stator are allowed to move in opposite directions,  the setup may become perpetual.   If you hold either rotor or stator stationary,  it may act as reaction (supporting force) and setup may come to equilibrium at some point.   You also may have to raise the initial speeds of both rotor and stator to some 'minimum' speed by applying external force, after which the setup may become perpetual.
