Some of you might want to try this. Get some old clothes hangers (wire). Cut (6) pieces 6" long each.
Bend each piece in halve until there is a 3" space between each leg of the piece.
It now looks like a open end triangle or a "V".
Take (3) of your Bowman magnets 3/8" X1" and stick them together making a now 3" magnet.
You don't have to glue them together. There is now only one bloch wall in the combined magnets.
Lay your "V" 's on the floor in a line. Place a piece of Plexiglas on top of them and place your 3" magnet
at the starting "V" and see if you can get it to roll on top of the Plexiglas through all the "V" 's.
The triangle "V" is a one way gate when combined with the other "V" 's. Now, if you get this simple experiment
to work. Can you put the "V" 's on a wheel and get it to turn continually?
WOW it really works in the linear configuration you described! I used
15cm pieces bicycle wheel spokes bent in equilateral V configuration.
My magnet was 15pcs stack of 12.6mm od x 5mm thick disc magnets. The
only problem I can see with the triangle gate is that the iron
probably slowly magnetizes in the long run. How would this affect the
The rotating hamster cage type of wheel made out of multiple triangle
gates would be a nice idea (the magnet wouldn't move I assume, the
wheel would rotate around it). I wonder if it would be possible to
use magnets for the triangle gates instead of iron (I'm still worried
about iron magnetization), might also increase the power somewhat.
Thanks Robert, nice to see something work for a change, there has
been quite a lot of frustration with the MXLO motor....
Here was my test is I cut small triangle about 18 gauge and mounted it
under my model plastic train. then I put 1/4 rods in rows under
plastic plex. I was amazed how the train moved over the rods and went
to the other end. Thought about making a circle but got distracted
with other things as you know. It seems the iron was gauge and
regauging as it went over. Here is the triangle word again!!
Eric, Norman, Robert and others,
I placed the six triangles (equilateral V shape, 7.5cm side length)
in a track configuration with 2cm distance between tips of the
triangle. Looks like this: >>>>>> and the magnet travels from right
You can adjust the driving force at least by making the triangles
closer together. Also possibly by using thicker iron wire and smaller
distance between tracks and the magnet (I didn't have a suitable
plexiglass piece at hand, used 6mm thick cutting board which is too
short for long tracks).
I also noticed that if you make the V of two separate pieces (so you
don't bend it), it won't work as well (or perhaps not at all). It
seems to need a magnetic connection between the sides of the
triangle. I think the whole point here is the bent V shape, thanks
I tried different configurations, works just fine if you start in the
middle of the sequence, it goes in the right direction (doesn't even
seem to have a sticky point or hesitation). I also tried angling the
base, works just fine with angles up to 5degrees I'd say.
Also, you don't need to give the magnet any sort of push, but it
accelerates smoothly and perfectly on it's own. You just drop the
magnet on the track and off it goes! Note that the track is quite
sensitive to the placement of the V's (they need to be in good
alignment for smooth operation).
The most amazing thing is that this linear V triangle track does not
seem to need regauging at all! This is really significant, as you can
have as long completely flat track as you wish! This is unlike all
other magnetic ramps (Adsitt, Naudin SMOT, TOMI device) that I know
Going to be a sleepless night tonight here in cold Europe... :-)
Mine works just fine without lock-ups, I feel that I could make a 2
meter long track with no problems, but that would require 100
triangles with 20mm spacing :-)
My wire is 2mm diam. My triangles have a 75mm side length. I got my
bike wheel spokes in 300mm length, so just cut them
in half and bent in the middle. My magnet stack is 75mm long and
12.6mm diam. I used plastic rollers at the ends to keep the rotor
straight and aligned over the track. The nylon rollers (actually
bearings with a short M6 bolt instead of a hole in the middle) are
32mm diam. The rollers lift the rotor 10mm above the plexiglass (not
a direct contact as robert suggested) and it still works, it actually
works better with the rollers as it helps to keep the rotor aligned
with the track. You can reduce the gap if you use smaller rollers (I
used what I had available at this late hour).
I noticed that you really need to have good alignment of the
triangles as well. Make sure they are all the same size and shape.
The gap between triangles is 20mm. The roller will go faster and pull
better if I reduce it.
I took a quick picture of my experiment, may be found in Tero folder
in the Files section. File name is
linear_triangle_track_experiment.jpg. I would have taken a video, but
my digital camera can't record video. Perhaps later.
Since everyone are onto the idea of iron and someone will come up with a working
magnetic motor soon I will tell you what my idea was, have you heard of the hamster
generator? well my idea was instead of a hamster running on a hamster wheel to
generate electricity, I was going to use a magnet as the hamster and iron rods around
the wheel for the magnet to attract, having seen the triangle gate, I would say that
will work even better then just iron rods around the wheel. It would work like this V
iron rods around the outside of a hamster wheel as the rotor, a magnet above the wheel
as the stator, on one side of the rotor a circle of button magnets like in the hamster
generator and coils wire outside the button magnets, as each V rod is pulled and pushed
through the magnetic slators field it moves the rotor, as the rotor moves it spins the
button magnets on the side of the rotor through the coils generating electricity. For
it to work the button magnets should be placed so they don't interfere with the V rods
and change the magnetic field in the V rods, the only other thing I see stopping it is
if the V rods don't work when they are placed in a circle like permanent magnets.
Nov. the 22th, 2005 I received a message from Dan. He suggested that I posted the
as un update to this page.
Here it is...
It is simple for you to duplicate the experiment from your site to confirm
I experimented with the Triangle Gate, only to discover is it just a simple
All pull comes from the first triangle, and after that it just coasts.
With a short track, it looks like it might work, but it will get stuck at
Simple proof of what I say, is to make a long track, and put the magnetic
roller in the middle.
It will not move. That solves that.
I also made over-sized and under-sized triangles, much wider, and much
narrower than the roller.
So, sadly, the "Triangle Magnetic Gate" is really a gate, and we must
continue the search.
If you find me in error, and that the roller is accelerated INTO,
and maintains velocity OUT OF and totally AWAY FROM the gate,
please contact me with the plans that work.
Thanks for the work you put into keeping your site up.
I shall now experiment with Graham's "Corner Gate".
