This motor was inspired by Butch LaFonte who is working on a similar overunity motor. My motor is a part of the LaFonte Research Group. It most closely resembles the motor in patent 5,258,697. electric car another article from Scott Mcguire

This patented motor will never be overunity because it depends upon large diameter wire and high amperage. It is controlled with complicated computer circuitry.

The theory is: The motor produces all power when there is no electricity and when electricity is used it does no work of attracting or repelling the rotor. The motor does require electricity to operate. This is explained in this website.

           

This motor proved the principle to me. It developed 330 rpm but was not load tested for horsepower.

I then built a much larger/stronger motor using neodymium magnets 1.25" dia by .5" thick purchased from Wondermagnet.

My first motor had complete negation of the attraction of the PMs to the cores of the EMs with a close air gap. There was no surplus "repulsion" power from the EMs. There were 8 EMs and 8 PMs. The new motor retains this configuration.

On the new motor I had problems in the prototype. The first problem was back attraction of the PMs to the EMs when they were energized to negate back attraction. This back attraction reduced power output and efficiency. Dynamometer tests confirmed 48% efficiency at 60 rpm. Motor size and bearings also contributed to inefficiency and I'll address this later.

This is my original electromagnet core.

They were made from Carpenter 4% Silicon Magnetic Steel. This steel achieves a high saturation level very quickly and retains no magnetism after the magnetizing force is removed. It is what the "experts" suggested. I wound it with 3 wires of 300' long 26 gage wire and energized it with 13 volts DC. The air gap between the faces of the EMs and PMs was .040". This provided for a combined attraction force of all the 8 PMs that was so strong I could hardly displace the rotor from the EMs by hand with the motor at rest.

The backwards attraction of the PM towards the EM while the EM was energized forced me to redesign the EM core. I used the same material with the dimensions shown next.

I wrapped this core with 9 wires of 300' long 28 gage wire and energized it with 13 volts DC. I got unexpected results. The repulsion electromagnetism against the PM was great as the PM was slowly moved closer to the face of the EM. But at about 1/4" air gap is where the "negation" effect of the EM on the PM occurred. Any closer and the PM would overpower the EM and be attracted to contact the EM.

At the 1/4" air gap if the PM were moved away from alignment relative to the EM there was no backwards attraction force present, rather there was repulsion force. The "backwards attraction of the PM towards the EM while energized" problem was fixed but now I had the 1/4" air gap limitation which greatly reduces PM to EM core attraction force.

I did calculations based on the original core which had 3 wires of 300' long 28 gage wire. If I replaced the 28 gage wire with 56 gage wire the electromagnetic field increased by a factor of 18 times while the current draw at 13 volts decreased 66%. I rewound the newest 1" diameter core with 36 gage wire and made 7 more EMs and rebuilt the motor.

My crude winding machine would break the 56 gage magnet wire so I used 36 gage wire. It took 42 wires of 300' long 36 gage wire to wrap the new cores to an overall diameter of 2.5".

Motor tests revealed that an 11/16" air gap produced the most power. Dynamometer testing showed .5 ft/lbs of torque at 220 rpm, with an efficiency of 26%. Power and rpm had been gained over the first combination. Not very exciting until you understand the inefficiencies of this huge motor design.

11/16" air gap provides for only a weak attraction force. The repulsion force is good. So the current version of the motor is more of a repulsion motor than a magnetic attraction motor. This is the point I'm at now.

This is a lot of "fat" to be trimmed off this motor.

• The shaft is 3/4" steel rod and weighs lbs.
• The rotor contains lbs. of aluminum and lbs. of steel.
• The rotor is highly non-aerodynamic.
• The bearings have a lot of friction from heavy packed grease.
• The cam/roller switch timing mechanism for turning on/off the
       coils is crude and "brakes" the motor.
• The wiring harness is not optimized for maximum current flow.
• The rotor contains steel which robs the cores of the EMs of
       attractive magnetic flux.
• The cores of the EMs are 2" long and might do the job just as
       well at 1" length which would cut power consumption in half.
• The motor contains only one rotor. The other end of the EMs
       could have a rotor facing them as well doubling the power
       output of the motor while not increasing power input.
• The cores are not precision wound because I don't have a fully
       automated winding machine. There is more air space within
       the windings which would not be there if I had one of those
       expensive winding machines which put the wires very close
       together uniformly.
• My stator coils are not perfectly spaced as it was not made in a
       machine shop.
• My dynamometer is homemade and has not been calibrated.
       I know I'm not accounting for the heat loss at the shaft.

My next step.

• The neodymium magnets are very strong and permanent. PM magnetism loss rate is one half of one percent every 100 years. When two magnets are stuck together it requires maximum effort to pull them apart.

• EM strength is caluculated using amp/turns. The number of times the wire makes a complete circle around the core times the total amperage flowing through it. The more amp/turns the stronger the electromagnet. But a winding can be so thick that the outer layers of wire stop contributing to the strength. Surplus windings only waste power and produce excess heat.

• the most attractive force at a .020" air gap
• uses the least amount of electricity in negation of the attractive force
• and at what intervals to reduce the power of the EM as the PM gets farther away

I will build a bench test device to test various PM/EM combinations. PM attractive forces can be measured at various distances and air gaps with this device.

I probably need to reduce the EM core diameter and wrap it to maximum usable amp/turns with the thinnest magnet wire to provide for the least power consumption.

A point will be reached where EM core diameter, core length, winding, and PM size yield optimum attraction force performance establishing the perfect EM/PM combination.

Then I will experiment with EM/PM distances to determine the motor's radius.

If I move a PM from it's center alignment with the EM the PM attractive force for the EM core will decrease to an insignificant level. This distance will establish the midway point of the PM between EMs. This graphic showes this process. The PM is green and the EM core is blue.

The EM strength needed when the PM is at a centerline alignment with it must be reduced shortly after the PM passes so that the excess EM repulsion magnetism doesn't repel the PM. I want the EM to be "invisible" to the PM when the EM is energized. I don't want electricity doing work. The easiest way to decrease the EM strength is to systematically turn off layers of winding starting from the outermost winding and moving to the innermost. This will yield maximum energy conservation. Several commutators are needed to accomplish this. The next graphic illustrates this systematic de-energization.

I will continue adding information to the website as work progresses. Right now I'm winding a new EM that has a 3/8" core diameter continuous to the end. The length is 2". I will intentionally put more wire on it than I think is necessary to achieve the strongest EM as possible. I will then take wires off, reducing it's overall diameter, until the EM has only that amount of wire as will add strength to the EM. Any wire that doesn't contribute to the strength of the EM wastes current and allows the coil to heat up more than it should.

After it is tested I will take the wires off, reduce the length from 2" to 1", rewind it and test it. My goal is to have as little energy consumed by the EM as is necessary. After I have my test data on the 3/8" cored EM I will build other diameter cored EMs and test them until I find the perfect match of EM to the 1.25" diameter neodymium magnets I have on hand now.

There are a number of other claimed overunity devices in operation today as well as proposed overunity devices. In no particular order here are the ones that impress me as having real industrial potential if they are truly overunity. As far as I know there are no proven overunity devices because if there were they would be on the commercial market and the owners would be billionaires. Please correct me if I'm wrong.

Claimed Overunity Devices

Howard Johnson Permanent Magnet Motor
I really like this invention. It requires no external power supply and relies on continuing imbalance of interacting north and south magnetic fields from the stator and rotor. Mr. Johnson believes he can easily construct a 1KW generator powered with this magnet motor.

Bedini all North Pole motor
This self-sustaining motor recharges the battery and does work. Another builder has verified this to me. The rotor has 4 permanent magnets and the stator 1 electromagnet wound with two different sized wires. As a PM approaches the EM it induces a voltage into the smaller wire turns on a transistor. Current then flows from the battery through the transistor to the larger wire in the EM providing repulsion magnetism pushing the PM in the rotor. As the PM leaves the EM the induced voltage to the smaller wire ceases, the transistor closes and power is cut to the larger wire. My guess is that Bedini is harnessing the CEMF from the collapsing motor drive electromagnetic field and sends a voltage spike backwards to the battery interacting with the physics of the battery and somehow recharging it. If this device can be replicated on a large scale the implications would be huge.

More to come. I'm studying many more overunity devices and will post them when ready.
