My Scooter Wheel Energizer

[SkyWatcher]

Hi folks, I was looking around energetic science forum and realized i had a garbage picked scooter just waiting to be used for something technolike.
So I'm building an energizer with a scooter wheel, 3-1/2" diameter wheel and using four 3/4" diameter X 3/8" depth ceramic permanent magnets.
I have built a few self triggering energizer type wheels before, though not a scooter wheel and the only energizer i built that had decent bearings, i used a reed switch, so that does not qualify really.
Anyway, will be something fun to look at, rotating away on the table.
Here is a pic so far of me progress, just have to work out how to mount it horizontally to a wood plate, meaning flat wise.
Let me know what you folks think and share any tips you might have from your projects, thanks.

Hi folks, my scooter energizer is ready to test, will fire it up later today sometime.
It has 24 awg. bifilar coil, i used an inductor from an audio crossover, the laminated core is probably 1/4 the size of the permanent magnet.
2n3055 w/heatsink.
Each 24awg. strand is 2 ohms.
Any comments are welcome, when i get it running good and charging some batteries, I will post a video for those interested.
I also plan to make experiments with this setup, like pickup coils and maybe some magnet behind coil tricks to see what happens and since the speed should be fairly high, I will try the speed up under pickup coil load effect, like thanes work and others.
Here is a pic of the setup, ready to start testing.

Flying magnets

Hi SkyWatcher,

That is a very nice looking setup. I am concerned about what is holding the magnets in the wheel. At the speed your wheel will probably turn those magnets could come flying out like bullets. For safety I think I would at least wrap a couple of turns of fiberglass packing tape around the outside of them. Please be careful.

Respectfully,
Carroll

Hi carroll, thanks for the reply and kind words.
The magnets are recessed a bit into the wheel and i used thick super glue.
I would think that would be strong enough, though I'm not sure.
I don't have any fiber packing tape, i have duct tape though, that has some fiber reinforcement i believe.

This is an SSG, isn't it? And we can take power off the
shaft so long as we re-tune every time we alter. Since
there are three vacant magnet stations, you could put
three pick up coils infront of them and send the voltages
back to a new battery.

[SkyWatcher]

Hi wrtner, thanks for the reply.
Yes, this is an SSG and i do plan on trying pickup coils, want to see also if i can get some speed up, under pickup coil loading effects.
Has anyone built an SSG or energizer as it is called also sometimes, if so, please feel free to share any pics or information, thanks.
Am going to fire it up now.

Hi folks, I have been testing the scooter wheel SSG, it is working well.
I initially used a 1.5kohm base resistor, though that caused the coil to self oscillate without rotor movement, then i used a 1kohm base resistor and it was hit or miss, then i put two 1 kohm resistors in parallel for 500 ohms and it no longer self oscillated and started to accelerate nicely when given a spin by hand.
Then added another 1kohm resistor in parallel for around 333 ohms base resistance and it improved acceleration, top speed and charging for an input at 12 volts, 200 milliamps using a 7AH SLA.
Also charging a 12 volt, 7AH SLA off the flyback diode.
No heat noticeable anywhere and the second battery is charging well.
I will post a video later for those interested.

Video of scooter wheel energizer

Hi folks, here is a video of the scooter wheel rotating away and charging another 12 volt, 7AH SLA battery, while drawing around 180 milliamps.

Tuning is very crucial. It might be helpful to refresh your memory
of the process at page 18:

p.s. Remember that every time you change any element of the setup,
possibly by adding pick up coils, re-tuning is necessary.

[SkyWatcher]

Hi wrtner, thanks for the reply.
Thanks for posting that pdf link, it will come in handy as i run tests on this setup.
I ran some battery swapping tests yesterday, just to get an idea of how it is charging and it was going for at least 6 cycles before a slight over all drop of about 10 millivolts in each battery, so it appears an efficient setup so far.
Many tests to come.

Hi folks, After only one partial charge cycle, I can't take the racket anymore, the scooter wheel bearing apparently is just to worn out and is like water dripping on the forehead, hehe.
Sooo, I am going to use a mountain bike wheel, 27" i believe and will mount many rectangular ceramic magnets i have laying around.
This bicycle wheel has very nice bearings and will run quiet and smooth.
Just have to work out a mount system for it and make a new coil.
The other scooter wheel was charging fairly well though, i will see what the COP turned out to be with that small test when i discharge the battery.
Here is a picture of the mountain bike wheel, it is steel rim, though hopefully it will still work ok.

edit: i take that back, it seems the wheel is aluminum and the spokes also might be aluminum as they also don't attract the neo magnet i used to test for ferromagnetic properties.

Hi folks, here is the coil I will be using and the magnets.
The coil is 5 strand 24 awg. and will probably just parallel 4 of the strands together and use the 5th one as the trigger.
I used coat hanger wire that had thin paint coating.
Here is a pic.

Parallel strands

Hi Tyson, nice project so far.
I'm not sure but I think if youput the 4 strands together ,it will act as a single strand of a heavier guage similar to ~18 awg.
In that link by Paul-R (btw thank-you) ,it say's for the wire to not be more than 3 guage sizes apart.
I could be wrong though, maybe someone with more knowledge can clarify.
Good luck

Hi shylo, thanks for the reply.
Yes i read that also, i already had this coil wound and just added the coat hanger core, so we'll see how it goes, i can always rewind later, if it doesn't work out well, thanks for the tip.
Have you built an SSG with a bicycle wheel or anything similar, thanks, if so, curious how it worked out.
Anyone else care to chime in and offer their experiences and results with SSG bike wheels or similar, thanks.

bicycle wheel SSG

Hi tyson,

I have built a couple of them and they work very well. With the larger wheel you just have to take your time as you tune them because of the extra mass. In other words you adjust the pot and wait for a few minutes for the wheel speed to stabilize. I have also helped a couple of other people with their builds and we have all gotten ours to work just fine. I am glad to see your wheel is actually aluminum as everything I have read says steel does not work well. One of mine is aluminum and the other is some kind of polymer I think. It looks like plastic. Both seem to work about the same. Your magnets look just like the ones I used that I got from Lowes so they should work fine. Your coil also looks like a very nice job. I am curious to see how the multistrand coil is going to work for you. My feelings are it will work even better because of the lower resistance of the parallel wires. I guess we will see when you get it going. The only other thing I can think to tell you is to be sure and clean out all the grease from the wheel bearings and then use some light weight oil like 3 in 1 oil on the bearings. Also loosen the bearings a little so there is just a little play. The Bedini group that I belonged to said the wheel should spin for at least a minute of so after you give it a hard spin by hand. This is before you mount the coil because the coil will give you a lot of drag. Also the bicycle wheels work best if mounted vertically. The bearings just don't seem to spin free if the wheel is mounted flat. That is all I can think of for now.

Later,
Carroll
