OS:Screw-Magnet Motor
From PESWiki
The Screw-Magnet Motor Crude Prototype consists of four rows of screws, off-set around a cylinder, which appear to cause the cylinder to spin when a holder of four neodymium magnets is brought close to it.

- Magnet Motor Prototype - "This is a video of a working free-energy magnet motor I made last month. This was the small-scale prototype for a free-energy magnet motor I am manufacturing. Only time will show that this device is legitimate. The final design is very different and much bigger. This is still the only working device I know of. Feel free to contact me for independent verification." (YouTube; Oct. 15, 2007)
How it Works
Quoting from the subtitles in the Oct. 15,2 007 video.
"This motor uses magnetic attraction to spin. It is basically a cylinder with flat screws attached to the outside. I mounted this on a hard drive spindle. Four neodymium magnets line up with the four rows of screws. The magnets are attracted to the screws, but are attracted more to the heads than the tail ends. The head of a bottom-row screw will be attracted to the bottom-most magnet. So will the head of the screw above it. The cylinder will turn to compensate this imbalance. The same with the next two rows of screws. The lowest magnet now prefers the head of the next screw rather than the tail of the previous screw because magnets are attracted more to the thicker part of the screw. When I move the magnets close enough, the magnetic attraction makes it spin.
"This device is a very crude rough draft. The screw placement is off, and it doesn't rotate smoothly. This is a quiet, environmentally-safe, free-energy device. On a large scale it could produce useful energy."
Quoting from overunity forum
"The aluminum bracket for the neo magnets is held on by one screw. Its fastened tightly enough not to swing into the screws, but loose enough for me to be able to rotate it by hand. As for the hard drive spindle, [it] was the most convenient thing I had back then, but now I have several bearings I can use. I've been busy lately but I can a better video made soon(ie to give more angles of the device then even fully disassemble it).
"I noticed too that the audio throughout the video was off by a half second, I don't know why this is."
"The motor in the video was made out of a piece of pvc, the magnets are(I think) Nd45, definitely with poles on the smaller ends. Screws aren't really necessary, you can build one by cutting washers in half and grinding one side down. Here's a picture of part of a tiny spindle for a desktop toy using the washer design:
This design makes it easy to adjust the angles the washers relative to each other; less change in angle=more torque, more change in angle=more speed, less torque(this can also be accomplished to a degree by changing the magnet arm angle). The above design uses a lot more magnets. I recommend a shaft made from a non-ferromagnetic bolt."
"I am planning a large demonstration so that I can take care of all of these verification requests at one time. The demonstration will be held in either Chico, CA or Sacramento, CA on a date which will be listed on the website as soon as it is launched. At this meeting hopefully all of your questions will be answered. Thank you, and I appreciate your support,"
Observations
On the Overunity forum, user "zero" notes the proximity proportions of the screws. [1]
Materials
"I believe the device in this video used nd45 bar magnets, poles on the small ends."
"I think the screws were 3/4in. Honestly screws were a bad idea and took a lot of work flattening, you can probably find something better than screws."
"The motor in the video was made out of a piece of pvc." [2]
On Oct. 19, 2007, Eric Vogels writes
I [ground] a screw. I held one against my grinding wheel and I [ground] a bit of the whole side of the screw, not only the head. Now the part of the screw that is left, fits very well on the round PVC. I tried to make a photo but I cannot zoom in so I made this drawing to show what I mean.
FAQ
- Q. How long have you gotten it to spin?
- A. I've left this one going all night, eventually the mounting screws need to be tightened since its mounted on fiber board.
- Q. Why don't you mount one or two more magnet rows spaced around the cylinder and get some speed cookin'.
- A. I eventually did that.
- Q. How is your new device coming along?
- A. Yes you will have a much more efficient, streamlined motor very soon.
- Q. What's the catch?
- A. Magnets depolarizing is probably what will eventually happen.
- Q. If the screws are iron or mixed metal, why wouldn't they become saturated after a few turns, and then stop? Have done something like this but had this problem.
- A. It takes a lot of work to polarize a piece of iron, a lot more than is going on here. The only way I've ever been able to noticeably polarize iron is by holding it to a magnet and hitting the iron with a hammer, helping rearrange the iron's structure.
- Q. Can I buy one?
- A. Yes I have a smaller one I can sell you, pm me.
- Q. To make a video like this, one could use a fan to make the cylinder rotate, and then the audio could be replaced to eliminate the fan noise (this would also explain the 1/2 second delay in audio). How can we rest assured that there is no hair dryer nearby?
- A. The abrupt speeding up and slowing down of the rotor in the video are not consistent with the action of a nearby fan, but are indicative of magnetic action.
Validation
Unit Purchased from xpenzif

- kossxf [Oct. 17]
- Can I buy this from you?
- xpenzif [Oct. 17]
- Yes I have a smaller one I can sell you, pm me.
- kossxf [Oct. 22]
- I have one of his devices. Its supposed to be mounted on a stepper motor in a way that lines up its push/pull with the screw alignment. It's like two systems balancing out each other. he doesnt mention it in his video.
- klicUK [Oct. 22]
- does it work?
- kossxf [Oct. 22]
- Yes it works fairly well.
- niente [Nov. 2]
- Could you please publish a video of the working device you bought from xpenzif?
- kossxf [Nov. 6]
- I can verify this information. I still have this device and it still works and the magnets are still polarized. I brought it to my college's science department earlier today, and they spent their whole class time in awe, and nobody could provide answer as to why this doesn't violate CoE other than the magnets depolarizing over time. I will post more on this if they give me any more hypotheses. I can also get someone in the department with a video camera to make a video.
- niente [Nov. 8]
- Thank you for answering me. I think that it is very important to have asap a clear video showing the motor running by itself for at least 2-3 minutes, and also high resolution photos and details of this device (before it disappears forever, as it usually happens). So please shoot this video before it's too late! We'll be VERY grateful to you. Thank you very much for all your efforts! ;-)
The following are PMs between niente and kossxf:
- niente [Nov. 5 2007]
- Hi, I'd like to know if xpenzif motor you bought is self-running or not. Could you please post a video of the motor running for at least 2 mins? Thank you.
- kossxf [Nov. 5 2007]
- Yes it self-runs, i'll post a vid as soon as I can get access to a video camera. I brought it to my college's science department and I am sure I can get them to make a video of it.
- niente [Jan. 21 2008]
- Hi, do you have any news? Have you found a video camera to document the self-running motor? I'd really like to see it :-) Kind regards ;-)
- kossxf [Jan. 22 2008]
- Yeah ive posted a video like three times and its been flagged and removed.

Semi-Success (sampling)
On Oct. 20, 2007, Bossnik wrote:
I have had marginal success replicating this device. I have flattened all screws and positioned them perfectly. I have gotten over 360 degrees of rotation(which I feel is very significant!) I am using an old stepper motor for a mount, but a smoother bearing might do the trick, UNLESS xpenzif's design incorporates the small bits of attraction and repulsion that you notice in a stepper motor when you try to spin it manually. Maybe he staggered the screws to line up somehow with that effect. I PM'd him asking about this and I'll post his response, this could be a key piece of the puzzle.
See OS:Screw-Magnet_Motor:Replications
Diagram illustrating the push/pull of a stepper motor when spun manually. The pull(green areas) should be located above the tail-end of a row of screws to help disconnect the tail ends and reconnect the magnets to the heads of the next row. Timing is a critical part of this design.
Patents
Xpenzif mentioned a patent pending in a PM, hinting on the use of a stepper motor or something which behaves in the same way when spun manually.
