Gravity Motor with Permanent Magnet Assist
Named the "Andy Motor," invented by Tom Ferko, this open-sourced design combines the principles of gravity and magnetism to create a rotating device, whose torque can be harnessed for energy. These plans are being shared openly with the world.
Working prototype was destroyed. Another is being produced.
: "If you or someone you trust makes the gravity motor with permanent magnet assist exactly as illustrated you will be in for a surprise."
The following proposal by Tom Ferko was published at FreeEnergyNews.com on March 17, 2004.
Tom Ferko's Magnetic-Gravity Motor Idea - Concept of combining gravity and magnetic forces to create rotational force came in a dream. Looking for feedback.

Eric Vogels did an awesome job in illustrating how the motor presents itself. In fact he illustrates a few improvements I did not think about. That's what happens when more than one head gets involved. It is my wish to thank you, Eric, Wayne Jones, Dan Quale, Jim Ross, Peter Sotropa, and many others who have helped me out in the past and present in regards to free energy projects. Dan Quale has all the motor info posted on his Overunity Builders website. Eric, Wayne and I have been communicating steadily over the last three years with each other. Some times all three of us were working on different projects.Those guys had to keep their sanity in check when I came up with some wild ideas. I always was loaded with them
Jim Ross was kind enough to illustrate all this on his web page also. Peter gave me a lot of good ideas.
I have communicated with Jim and Peter already over the phone in length.
I wish to say that steel is made in many grades. some will be attracted to any given magnet with great force. Other grade steel hardly attracts. Magnets are made the same way. Some attract greatly and others don't. This is where experimenting has to come in. The top 12 o'clock magnet MUST be able to STICK AND ROLL along the inside of whatever grade steel hoop is used.
Next use that good setup and check the magnetic fields on the light side of the motor.
The rotor magnets are the closest to each other at that point and their fields should not or hardly interact with each other.
Make sure that all eight sliding rotor magnet wheels roll straight, smooth, and evenly. If they wobble there is a possibility of a hang-up on the iron hoop. The motor will stop.
All torque focuses on the center rotor hub. The iron ring is stationary, the rotor rotates around the insides of the offset center point of the iron ring. That offset is about 1/4 the diameter of the ring. If you use a 16 inch diameter iron ring then your offset center point should be 4 inches from the outside circumference. You might adjust this if you have trouble with magnets to close to one another on the light side.
I hope the many free energy advocates out there pool their best thoughts and engineer this device to perfection. We can beat the high energy bills and have a greener earth. If you really want to get rich yourself personally all you have to do is buy stock in any place that makes magnets. Don't hinder this project.

On May 19, 2006 in response to the question: "how long did it run continuously? total time running longest time running in one test approximately how much torque was it putting out?", Tom Ferko provided the following reply:
: "It ran 10 minutes straight-- very slowly. Although it ran, it did not seem to be very powerful, as it was a small prototype.
: "I never tested it and as you know it was destroyed. I am slowly constructing a larger prototype. I really am interested in a motor that can do usefull work."

The neodymium ring magnets (colored red) slide on eight arms and ride the insides of a split steel hoop.
All ring magnets used in this fashion will roll and slide on steel easily. They are used as gripper "wheels".
Two separate jpegs illustrate how to construct the simple sliding carriage that the ring magnet "wheels" are attached to. One carriage is used for each of eight rotor arms.
Magnet polarity is no factor in this design. The ring magnets single purpose is to "track and hold onto" the inside surface of the steel hoops. That's all. Gravity is what makes this motor operate.
Constructed as illustrated, the motor i perpetually imbalanced. The right side of the motor is heavy and the left side of the motor is light.. That is made possible by off setting the motors axis.
The motor illustration will give you a fair idea of how the motor looks after building it to whatever scale you desire. A quality center free pivot bearing that will support the entire load is a must.
The motor is not a speed demon by any means, but it will rotate into the next century, as long as the magnets hold power and gravity exists.
Check EBay and look for an inexpensive pair of steel drum hoops/rings. 16 or 20 inch diameter suggested.
Your split hoop search will be ended.

Even before you start this project, take a HEAVY neodymium ring magnet you have and put its rounded side (not flat side) on the steel sides of your home refrigerator. Turn it loose, and watch it roll/slide to the bottom of the fridge. All the while, however, the ring magnet clings to the fridge.
This single, simple, basic concept is used throughout the GRAVITY MOTOR WITH MAGNET ASSIST.
I cannot stress hard enough that the ring magnets must be used as wheels as illustrated. If used in a different configuration or with any other shape of magnet, lock-up results when placed on a steel ring.
Another point is that all the magnets on the light side of the motor must have ample spacing between them so their magnetic fields do not inter react with each other. Notice that each rotor arm magnet spacing is closer on the light side of the motor. An experimenter will have to work with this in mind.
When any magnet reaches the 12:00 position or highest point in the hoop, it must be able to cling/roll/slide on the hoops inside. That leaves out weak ceramic ring magnets. I suggested using neodymium magnets. If the magnet does not have that type of magnetic power, it will break free and slide down its shaft when it is in the high noon position. The end result is an inop motor. The ring magnets HAVE to carry their own weight, and that of its support carriage, all around the inside of the ring.
Of course, when you use a ring magnet with a lot of power, then you have the spacing problem to deal with on the light side of the motor. It's a catch 22. With a little thought, all can be accomplished.
Any non-ferrous material can be used for construction. The shaft bearings and the steel rings are the exceptions. The rotor arms should not flex, and most plastics do. Phenolic or stiff plastics are good. They must be bondable, however. All poly plastics, Teflon, nylon are not bondable. Thinwall brass pipe is excellent as it is light weight and bondable.
The magnet carriage should slide freely on the rotor shaft and can be made out of any "slippery" plastic, like Teflon or Nylon. Since Teflon cannot be clued, all construction joints will have to be pinned.
The following was submitted by email from Tom Ferko, April 24, 2006 posted the next day.
A lot of people now think I am real crazy but this does work.
As a simple demonstration take a roll of heavy powerfull ring magnets and
wind a layer of tape around them so they dont chip. You now have a
Now take any large empty steel coffee can you have lying around and "stick"
the roll of magnets near the top or 12 oclock position and let it loose.
Notice it does not fall straight down as it is attracted to the sides of the
can. But it will roll like there is no stopping down the sides and to the
bottom of the can ---and then some more ---because of gathered enertia.
That roll ( wheel) of magnets will do the same thing inside a 55 gallon drum
if you think about scaling up.
Now take your finger and gently push the roll of magnets up the other side
of the can. See how easy it is to do. They roll up but stick to the cans
side all the time.
I have included a jpeg which shows the coffee can and a roll of ring
magnets near by.
A wood model of one sliding brass magnet wheel carriage
is also shown.
I sure wish now that I never destroyed my original prototype.
When scared I regretfully did a very stupid thing.
The whole motor concept is based on this simple demonstration. Extremely
powerfull ring magnets work the same way. Weak magnets won't hold their own,
weight much less than the heavy carriage they would also have to support.
That heavy carriage supplys good weight on the heavy side of the motor.
In turn the heavy side of the motor always imbalances the light side.
Keeps turning slow but sure.
The prototype was destroyed, and no videos were taken.
The reason I destroyed the prototype is for some strange reason forwarding jpeg photos on my computer to ANYONE connected to overunity did not work. I could send out family photos, scenes, ect. to anyone with ease, but try to send out anything related to free energy in the way of photos did not work?? I managed to send everything to the overunity builders web site where all is shown now. How that happened is a mystery. Why no free energy photos and at the same time family photos go through?
Running scared I acted too hastily. Thinking more clearly about this now, I am reconstructing a model with 16 inch diameter split steel hoops.
The previous prototype functioned all the time, and I had to grab the swinging rotor arms to stop it.
I never measured the torque but its speed was slow. I would have to call it a slow-but-high-torque motor.
It had a 12 inch diameter split steel hoop.
It cost around $200 to build, with ring magnets, brass tubes, shaft bearing, magnet carriages, plywood support sides and base.
I did this slowly over a long time figuring one thing out before I started another.
The unit will stop working when one of the following gives up:
1. The eight magnet carriages loose their ability to ride smoothly on the rotor arms.
2. The magnets loose their gripping power and slide away from the insides of the iron ring dragging their support carriage with them.
3. The central rotor bearing wears out.
4. The earths gravity quits. (Ha Ha!)
It would be extremely easy for anyone in the world to replicate, that had machining skills and good craftsmanship.
It could immediately supply energy needs of mankind by harnessing its rotating center shaft to power anything. Geared up motors, generators, ect.
Each person using the basic concepts stated can construct large or small motors scaled down or up to any size or power required.
[Note: Only one prototype of one size was built, and worked. The scalability is an extrapolative assumption.]
I would like to see any group or individual contact me for production and make this affordable for anyone.
I never was into this for money or fame.
As far as any monetary royalties are concerned, it is my wish to have any and all royalties sent to St. Judes cancer research for children. No monies to me personally.
My only other request is the device be named the "ANDY" motor. This is in rememberance of two special persons in my life who are no longer with us. Both Andys would have shown a keen interest in it.
My hope is the entire world tries this out.
If an industry might be interested they can contact me and spend their own money. They can even patent and market a commercial version of this motor, with the idea that anyone can make a homemade version. I want it to be seen and used. Not hidden.
I got the basic magnet (roll/slide) motion idea from one of Butch Lafontes projects and ran with it.

Gravity Test Motor Might Work as Magnet Motor Platform - Replication variant of Tom Ferko's gravity motor with magnet assist design turns out to not self-rotate. However, the dynamics of motion near the fulcrum point provide interesting possibilities for a possible magnet motor application. (PESN May 12, 2006)
Partial Assembly Drawing
The following was received by R.R. on May 29, 2006.
: The Andy motor looked very interesting and fairly easy to build so I went for it. I am not really fond of sharing failed attempts but maybe someone will benefit. My version is not the most friction free design but I saw no evidence of auto rotation. Maybe someone with better engineering skills will have more luck.
This motor could also be made without using magnets. Metal cylinders between two metal rings could be substituted for the magnets and the steel ring. The problem of magnets not sticking to some varieties of steel would then be solved. I will include a diagram soon, as I think this description is vague. I haven't tried this but if any body does try tell me if it works.

Comment : This is precisely what Ken Hegemann did (see photos in earlier section), and it did not work.
