What to watch for
- ▸Speed kept increasing even as cap bank voltage dropped below 10V

- ▸Coil positive end had the main cap bank, small cap bank, and power supply clipped together
- ▸Induction from the spinning magnets fills the caps and makes the motor go faster
- ▸No battery or constant power supply needed once running
- ▸The Bedini does spike goes directly to the cap bank clipped at the coil positive end

I hooked up a cap bank to the coil positive end on my three magnet system 120 setup and watched the speed climb while the main caps discharged. The Bedini does spike keeps feeding energy back, pushing RPM higher with induction alone.
Key takeaways
- Speed kept increasing even as cap bank voltage dropped below 10V
- The three magnet system 120 degree rotor hit nearly 3900 RPM (1300 x 3)
- Coil positive end had the main cap bank, small cap bank, and power supply clipped together
- Induction from the spinning magnets fills the caps and makes the motor go faster
- No battery or constant power supply needed once running
- The Bedini does spike goes directly to the cap bank clipped at the coil positive end
I fired up the three magnet system and let the cap bank charge to 13V before pulling the plug. What happened next surprised me—the rotor kept picking up speed while the voltage sagged. That's the kind of thing that makes you snort and laugh at the bench.
We monitored the multimeter and the little cap bank in the back. The presence of that extra capacitance clipped right to the coil seemed to help everything. I heard the transition as it accelerated past 1000 RPM and just kept climbing.
The coil is 1.5 pounds of 32 gauge wire with about a quarter underneath the wheel. The field reaches out, so even the offset part gets some action. I jiggled the resistor once and it throttled right up—almost 1300 on the meter, which works out to 3900 when you account for the three magnets.
When the Bedini does spike, that energy heads straight into the cap bank. I love how forgiving this setup is. You don't need micron-level precision; just hook things up right and it runs.
I unclipped the grounds to shut it down and watched the little cap bank continue to climb from the coasting induction. Pretty neat to get these results without a battery sitting there the whole time.

So, we got 12 volts in the cap bank now. I'm about ready to pull the plug here. I'm going to let it get 13, maybe. On the multimeter there in the middle. Maybe 1250. We'll see what's up. So, I'm going to come on shut it off. So, cuz I'm just charging the cap bank right now. It's going pretty fast. Give it a little bit more. Cuz that's basically what we're doing. So, the value is 13 and about a an amp to force charge the cap bank. All right. Now, I'm going to shut it off. It's going to start to go down. But, the value of this little cap bank in the back is going to go up. So, I think all in all, since they're all being put into the same place, which is the coil, I'm going to monitor the speed. I think the the presence of that cap bank and it being hooked up to the same place is >> [snorts] >> a good good thing, good sign. Yeah, it's starting to pick up. Huh. Oh, let me try and uh There it goes. Anybody heard that transition? There it goes. Yeah, it's going up pretty steadily right now. It's currently not maglev, so it won't reach astronomical speeds, but Oh, we're at 1,000. It's a three magnet system, 120°. Yeah, see it keeps on getting faster and faster even though the voltage in the cap bank is going down. There's got to be a reason for that. Either it's sinking into the resistance that's right here. Yeah, I had to cut that back, man. That was uh a little nerve-racking. Oh. Wow. Dude, but that's so like just phenomenal, man. I mean, it's like you don't really All I can say is that the induction as it goes faster, it fills those caps up, and the higher those caps are, the faster the whole thing goes. Because it's it's clipped right here to the to the coil. And then in order for it to get to ground, it has to go through the this. I just think it's it's awesome. Because it's not coming from a power supply. Right? And it's not coming from a battery. Definitely no battery. Just this cap bank and that cap bank. And I'm pretty sure uh as long as there's enough capacitance, the values can vary. She variants and ranges. That's what I like working with, okay? I mean, I don't the exact micronicallyn sector uh wherever whatever's going on, man. I mean, that's it's it's definitely necessary for for a lot of things, but for this, I don't I don't think. I don't think so. I think this is very forgiving as long as you know what's what and what's what. You know, I just jiggled the resistor right there and then there's the probably one of these connectors is a little, you know, open. And it just throttled right up. All the way up to a like almost uh you know, 1,300. Right? Almost to like uh 3,900. 100 3,900 and then you divide by three. The 1,300. Perfect. See, and it's even charging it up now, as far as I can recall, just from it coasting past that coil. Or it's got to be the little cap bank, but it's not hooked directly up >> [cough and clears throat] >> to the to the big cap bank, so I don't know what's going on with that. I know that when the Bedini does a spike, that spike goes directly to the cap bank. I also know that cap bank is clipped to the to the uh beginning of the coil, positive end of the coil. You got three things clipped to the positive end. You got the cap bank, you got the little cap bank, and you got the power supply. The power supply is off most of the time. Um literally, this this thing will charge up in 2 minutes flat. Doesn't matter where it's at, pretty much. I mean, it's not like I let it get very low. But uh yeah, I think it's great. And I'm not sure why it increases in speed like that, but um you know, it gets to the point where it should be you know, you would think that it would start losing speed because it's lost so much voltage across the cap bank right here. And it just keeps increasing in speed and everything it has to do with the other cap bank being hooked up to this coil. Anyway, that's uh 1 and 1/2 lbs of 32 gauge. And it's it's a I don't know how far off set it is. It's like a quarter quarter of it's underneath the wheel here. So, there's a big 3/4 of it that's not directly being affected. I mean, it's probably being affected more so towards the center because of the way that the the field operates. You know, it goes out a little ways. All right, so There, that's about to go out. All right, so we'll spin it up. You can If you can hear it, it's chirping. That's a good sign. That means we're going to get speed. That means we're going to get induction. And that means that we might have the effect. So, this is just uh reading. It's a bounce back from the cap bank. It's the cap bank is at 1080 and it's saying 10 10 4. 0 amps. And saying 0 amps is probably something splashing back to the So, see how it's going down, you know, it's going down. Maybe it hasn't reached the potential yet. It's crazy, man. It is going so fast. All right. And if you can hear it, it is revving up. But, we've dipped below 10 volts. We are now at 9.9. >> 3,000 Wow, dude. 9.5 volts 100 1,111 Just put Round it off. Boom! Man, that is so cool. With less than 10 volts. Wow, man. Man, that is so neat. And then I don't know, man. It's just so easy for me. Um well, I just to unplug it, you know, like this. Other people would like maybe build a mechanical switch or crank or something like that. And I love seeing all that stuff. Makes me like want to do other things. But, you know, I'm uh unclip the clips. Yeah, I just disconnected both grounds from eating both cat banks and everything is shutting off. And then all this spinach is going to increase I don't even know. I maybe I'm wrong about that. I think the little cat bank is increasing, but I don't have a multimeter hooked up to it right now. Anyway, I think that's really cool. I I It's awesome for me. I feel confident not using a battery or a power supply and having awesome results. That's great. All right. Peace out.
