xpenzif lifts the board on which his device is mounted, to show that there is nothing attached under it.
"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]

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.

- 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)

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.
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.

Mr Allan,
I've written you a few times in regards to magnetic motors.. We
corresponded several several times during the mylow fiasco. Anyway, I'm
still hard at work trying to develop my own magnetic motor, and have
been following up with other people who may or may not have experienced
some mild success in their own endeavors.
Anyway. I decided to look into the screw magnet motor that is
featured on your site to see if I could verify the results shown in the
short youtube video. I was curious if the principle worked, as it's
similar the what Mike Brady did in the Perendev design.
Since the person who supposedly build the original motor was
supposed to have sold it to youtube user: Kossfx. I wrote him and asked
where the motor was and if I could see more videos of it or purchase it.
Here are the two correspondences he sent me:
- "I don't own it anymore but anyone can go see it at csu chico's physics dept." kossxf
- "Yes.. California state university chico has the one that was given to me. xpenzif said it was perpetual motion when really its just a worthless elaborate way to depolarize a magnet." kossxf
So, I'm curious, does anyone ever bother to check up on these guys, or do they just take them at their word? I contacted the California State University of Chico, and talked to two different people in the physics department that had never seen or heard of this motor. Here is some of the correspondence the I received from one of the professors at Cal State:
- From: Eric Ayars" <Ayars {at} mailaps.org>
- To: "john" <terriblelizard20 {at} yahoo.com>
- Someone BOUGHT one of these? LOL!
- I've been in this department for seven years, now, and have never seen it. I would have seen it if it'd been here, it's just the kind of thing that we'd all pass around and laugh about. It's certainly not "on display" here! I don't know who "kossxf" is or what he's trying to pull, but if you can get his name I can determine if he was really a student here.

- From: Eric Ayars" <Ayars {at} mailaps.org>
- To: "john" <terriblelizard20 {at} yahoo.com>
- Looking further at this site, http://peswiki.com/index.php/OS:Screw-Magnet_Motor, it appears that "kossxf" is in on the scam rather than merely being a victim of the scam. He makes some claims in the comments section ("Yes it works fairly well", "I can verify this information", etc) that indicate deliberate complicity.
- Normally I just laugh off cranks/frauds/etc —we get them regularly in any physics department— but this one is besmirching the name of my university, and that pisses me off.

This is probably old news, but I'm just providing the information for you in case you would like to update the information on your site. Since your page on the screw magnet motor has a section where youtube user kossxf claims to have taken this motor in to the physics department at his college and let the students and professors examine it, it's only fair that one of the actual professors there has a chance to refute this claim. Just my opinion.
In the mean time, I'll keep pushing forward and working toward
building a real magnetic motor. Keep doing what you do. Your work means a
lot to all of us out here striving toward the dream of a better
tomorrow.
Do great things!
John [Warren]
