Hi Turion, thanks for the information on the spark gap and I look forward to details of how your motor build goes. Like I was saying, it's not too surprising the charging i was getting at 12volt input, since only around 1 watt was going through and since when the collapsing field occurs, in attraction mode, when the magnet is leaving the coils, the diode is conducting and so we have both events occurring at the same time and bucking one another, which reduces output potential of flyback. When using monopole methods with core, there is advantage as far as it's use as an energizer, rather than motor. Since ideally that method just nullifies magnet field. I'll try repulsion today to see how recovery is. Since in repulsion mode the collapsing field will not be conflicting with any lentz effects caused by moving magnets.

SkyWatcher,
Can't wait to hear about your results.

I'll be posting some pics later today as I start assembling my masterpiece. I haven't wound my coils for the motor yet, just the 16 coils for the Watson part of what I'm building. I lay awake at night figuring out the best way to wind those motor coils and still be able to replace them with a different configuration later without having to disassemble my entire project, and I think I have finally figured something out. I will be using some PVC pipe to make removable sleeves that fit into holes drilled into my stator, and the coils will be wound inside those sleeves. That way when I want to change my coil configuration I can just replace the sleeves. Then I can solidly glue the wire inside the sleeves, but only tack the sleeves in place with glue in a couple places so that I can cut it loose with a sharp blade later. I built a jig in my head last night that will hold the outside and inside pieces of PVC in place while I wrap my coils around and glue them in place. Flip the sleeve over and repeat the process on the other side. Then I will be able to pull the 1" inside piece of PVC out, and that will leave the coil all nice and tidy inside my sleeve. Now all I need to do is build what is in my head. I wanted to try the Tesla method of winding coils plus the standard method to see which produces the most flyback. Heading to Home Depot now to buy some PVC and then put my jig together. Will get those coils wound this morning and will post all kinds of pictures for anybody who gives a hoot.

For me, some of the more interesting things are the jigs and devices we build to help us more easily get things done. Like the jig I will make for winding these coils, and the coil winder I built that operates by hand or with a variable speed motor operated by a foot pedal. I think the more of THOSE kinds of things we share, along with our builds, the easier we make these projects for each other.

Don't mean to go on and on. Time to get to work!

@Sky

How do you go about winding them coils? You gotta jig or something? I got few ideas but I was just wondering..

will you only use why 6 magnets?

Hi SkyWatcher

Your rotor has the enough space to install 12 magnets, the effect will be perhaps better, will you only use why 6 magnets?

Hi SkyWatcher and all people

Uses more coils and the magnet, can have a higher efficiency?
how does the magnet arrange correctly? NNNN arrangement? NSNS arrangement?
in appendix picture 1-8 which correctness? Which efficiency is highest?

Hi folks, I tested the motor in repulsion mode and the torque was the same and the flyback recovery was a little better. Without cores, I don't think it's ever going to be as good for flyback capture when using rotating magnets that diminish the pulse input. Though it's meant to be a motor. Hi yx630514, thanks for reply. Yes I probably could put 6 more magnet stacks on each rotor, though they would have to be the alternate polarity. It may help performance, though not sure if efficiency would go up. I would still only use unidirectional pulses though. And I would try this if I had more magnets. Hi Turion, look forward to motor progress and nice idea for removable coils.

edit: yx630514, number 4 in your picture would be the one id try.

Patent number: US005514923A

Hi: All people

Patent number: US005514923A
[High efficiency DC motor with generator and flywheel characteristics]
United States Patent: 5514923

This patent should everybody know

This equipment uses 15 air core coils and distinguishes 12 magnets up and down? Why is such quantity coil and the magnet? What truth has? Its magnet polarity arrangement way is what kind of?

Hi yx630514, that patent motor is good also, however much more complicated switching. There are other variations which would be good and only require three sensing/timing switches and no complicated electronic controller to break down.

I've been thinking about the difference in generation between coils with and without cores. When a magnet passes a coil with a core, it will generate a voltage from that coil with the same polarity no matter which way the magnet passes the coil. This is because the magnet always polarizes the core the same no matter which direction it travels by. The core is what the flux travels through, not the windings.
An air core is a different story. With no core to polarize, the polarity of the voltage induced is relative to direction. There are also two pulses of power: one when the magnet crosses over the first side of the coil, and the next when the magnet crosses over the other side of the coil. Both these pulses are of equal and opposite polarity. This is because the magnets are generating current through the windings instead of through the core.
Anyway, I just though I'd throw that out there to help explain the difference in generator properties between the two types of coils. This difference may help to explain some of the unique behavior of this motor since the same rules apply to both.

Hi Ted, I think I understand what your trying to say. I don't have a scope or anything to check the same things others like Ben observed with this motor. Though if this pulse motor does briefly create an aiding emf when pulsed, I see possible similarity of 'Magnacoasters' design, where he uses a magnet at the back of a core and uses like magnet poles on rotor. When they pulse there coil, the magnet at the rear of core which has its flux extended through the core and pulls this flux back and through the core to a new point at the back of the coil, which is what Garry is claiming for this air-core pulse motor. I'm not sure what the rotor magnet function would be in the 'Magnacoaster' design, but I certainly see a possible similar effect in the stator coil/core/magnet. Could be the way he is getting that higher frequency gain he is claiming. I'm thinking about testing this, since realizing this possible correlation. Just a few thoughts, let me here your thoughts.

Building pancake coils

Here's a link to a YouTube site that shows the jig I devised for building the pancake coils. In the video, I only talk about building one half. To build the second half, you simply repeat the steps for building the first half, but you use the collar that already has a half a coil in it when it comes to the step where you slide the collar on. If you have any questions let me know.

Hi Turion, Nice method for making air-core coils you have come up with. Mine probably aren't as tight and nice as that probably makes them. I've gotten a little sidetracked as usual with pendulum stuff, however I am thinking of things to test or improve on my motor. How goes what your working on.

SkyWatcher,
I made a major change when I saw that patent yx630514 posted. I was going with smaller rotors and fewer coils and an equal number of both, but when I saw that patent I could not resist. I yanked my neos out of the rotors I had made and am in the process of building all new rotors and a new center piece to house my coils. The only thing from my original build I will use is the coils because I can put them in the new build. Only there will be 15 of them, which is why I spent one whole day figuring out that jig to wind coils. If I am going to wind a bunch of air core coils, I want to make sure I do it right. So I basically started over. That jig does make really nice, tight, compact coils. I also found that if I cut the piece of 1" pvc coupling with a hacksaw so that there is a single break in the ring and put a small piece of cardboard in the slot that I have cut that I can push out with a razor blade when I am all done, it lets the piece of pvc contract enough that I can easily remove it if I want to, in order to give myself an air core that is 1/2 inch larger. I don't intend to do that because I like the way my coils hold together with the system I have, but thought I would include that info here in case somebody wanted their coils without that inside ring, and intended to use "my" jig idea to build them.

I am using this motor to drive my Watson device, and had not planned on such a large rotor, so had to make some significant changes to my Watson device to allow the larger rotor to fit. All this has put me way behind schedule, if there actually IS a schedule.

I work on this pretty much all day long during the week, and then take the weekends off. It will probably take me to the end of next week to get everything together and assembled. I was going to post pictures, but now that I am starting over, the pictures I have are of something that doesn't really exist anymore.

@Turion
I appreciate that Jig. I did something similar. I gotta come up with something that powered. My old beat up carpenter hands aren't what they used to be.

Matt,
Since I plan on spending the next twenty or so years (about what I've got left!) messing with this stuff, I'v looked around junk stores for things I can really use. A company called Foredom makes this hanging motor with a flexi shaft. It also has a foot pedal so you can vary the speed and stop completely when you let off the gas. I got the largest diameter threaded rod it would take. cut it into lots of short pieces and welded double nuts with different threads on the end. Now I can screw a threaded shaft into the double nut and using a third nut on the shaft I am screwing in to lock things in place, I can spin any kind of shaft I want.

With the jig I made, I actually use a longer threaded shaft than the bolt I showed so the jig is suspended between two "L" brackets that are bolted to a piece of wood. That way I can spin it and wind my coils. I have several spools of different size wire that are also suspended and rotate freely. Thats what I am using to "power" my coil winding. When you are winding a lot of coils, it sure makes a difference. The only thing I hate more than winding coils is waiting for trains.

I should mention that the motor I show here has a standard plug on the end of it's electrical cord. The foot pedal has a female receptacle that takes that standard plug, so you can use the foot pedal to vary the speed of ANYTHING that you want to plug into it, which certainly has come in handy!
