video "Frenchie Test Motor"
“Frenchie Motor” Test Wheel Run.

This is the basis for my motor design. Trying to apply leverage to create torque force. This test wheel is able to run for 24 hours on one battery charge before it starts to slow down. After 30 hours I ended timing the run because the motor was slowing down. It may have run for another day before completely draining the battery.

I find this very exciting. If we had used a 12 volt battery drill to turn this wheel, from the centre, at 120 rpm our battery would be expired within one hour. But because we apply push to the outside of the wheel we use very little electricity to generate torque. I measured the power use to be .25 amps @ 12 volts DC

I am presently completing my newest motor design, much larger, and more powerful,. I am not ready to share the secrets of this new design yet, till it is finished and patented. As for my name here " Masternot " I am not a master in electronics, the reason for me joining Instructables. I am here seeking the help of a “Master in Electronics”, to collaborate with to complete the design work on my electronic sensor drive system.

Anyone offering any critical information that aids to my design will be remembered and receive recognition and rewards as per their contribution.

If your expertise is in Transistor switching circuits, motor controllers, power mosfets etc. I would like to here from you.

For anyone else this is a great fun project easy to build if the video is not sufficient to show you how just ask and I'll tell you all you need to know to build a " Frenchie Motor” test wheel.

What you have here, is called a brushless motor. They are frequently used where longevity and robustness is a concern. Have a search -- putting the magnet on the rotor and the coil on the stator has been used for a long time. Making it bigger has advantages and disadvantages.

As said in the other comments - to get a battery drill to perform at 120 rpm is way outside its intended purpose. Underpowering the internal DC motor means more waste. Also, the size of the battery on your drill is SIGNIFICANTLY less energy dense than the SLA battery you use for the full size.

Don't let anyone snap their fingers and dismiss what you have to say - but rather research the topic, know the language to speak, and use real science to make a claim.

Very well made. I like the idea of leverage. However, it is very unfriendly space wise, but I guess that's the product. Anyway, creating torque with very little amperage is a great way to do this. I like it. Perhaps you can demonstrate you trying to stop it by hand, or even run the drill in the opposite direction of the motor and then run it.

Where we need to concentrate on our design is the way that we set things up to push on the outside of the wheel. Designs that use both sides of an electromagnet to push and pull real magnets forward simultaneously will use less electricity to create our forward force.

We are turning electricity into force then amplifying the force with leverage then turning force back into electricity . The free energy has to be the product of how well our design turns electricity into force on the outside of the wheel.

This link will demonstrate what I mean about using both sides of an electromagnet in a design http://www.youtube.com/watch?v=9mBhlRtry4Q

Nice job. I like "simple" things, too. Building things at a larger scale makes it easier to make things without complicated fabricating machines and expensive processes, too.

I'd like to know more about this motor. Can you tell us more about the sensor device, the trigger circuit, the magnetic coils and the general operating design?

I wonder if you could get this motor to work by adding additional magnetic coils, and if that could be done with only one sensor, or if each coil-pair would require its own sensor.

I think you will find more info at this link http://www.youtube.com/watch?v=p4ZNiYevI_M

You can add more coils to this design to add torque power to the shaft. It's hard to increase the RPM, that pushed me to look for another way to manipulate the wheel. Have fun explore yourself.
There are special switches available, sensitive to magnetic changes.
But the technology of this motor is able to use every switch, which does not
act as a brake to the system.
You can even take a double ring of coils, just separated half a bow-length of the ankers arround the rotor-plate. The one number of coils (odd-numbered) will be supplyed with current when anker plates comming in reach and a litle while later the even numbered coils will be supplied for a short moment.

MOS-FETs are a good practise to amplify the current from your fast position-switch to the need of your coils. But don't forget flyback-diodes to protect the FET.
On using Flyback-Diodes you have to switch off a little earlier, because the magnetic field last a bit with the descending flyback current.
Even you could use the flyback energy as reflow energy to your battery.

Thank you el-haber, I think you are talking about the basic pulse motor design, yes I have considered all this, still prefer a reed switch so far to sense my timing

Your YouTube video isn't currently showing for some reason so I've not seen your design. Is your design elsewhere?

However, my comments are more about the second paragraph and your statement about the apparent efficiency of this design versus using a battery drill and the conclusion that because you push the outside of the wheel you end up with a more efficient motor.

In any system like this, conservation of energy means total energy in equals total energy out. The efficiency is the ratio between useful energy out versus energy in. The fact that this runs for 24 hours with this design versus using a drill motor is not in itself an indication of the efficiency of this motor per se but an indication of how inefficient it is to use a drill motor in this application. What is actually happening is that the drill motor is wasting so much energy doing something it's not designed for, in terms of wasted heat and turning friction relative to this design.

With your motor, you cut down the losses in the bearings and the pickups etc., both mechanical and electrical. You could get the motor to turn even more efficiently and last longer by making the bearing lower friction and optimising the coil, but as a motor, once you try to take energy out of it to make it do something useful you would find it is very difficult to gain any significant power from it. Try stopping your rotor from turning and it would be very easy. Then try stopping the drill motor turning.

What this design is, is effectively an electronic pendulum where the pendulum does a complete circuit. You might find this useful:

However, I do like the idea of motors that run for a long time with little energy needs, even if they don't do much work.

I think your statement what goes in is what comes out is ignoring" Leverage "

Pick up a pry bar with 10" of leverage. you push with 10 pounds of force at one end , you get 100 lbs of force at the other!

A wheel is a pry bar in a circle, and works the same way.

Put a motor designed to generate torque force with very little electricity with a motor designed to generate electricity from torque force, free energy!.

Find more info at http://www.youtube.com/watch?v=p4ZNiYevI_M
Thanks for the video reference, which I have now seen.

I'm not confusing leverage, which is more properly called torque, with energy. You are confusing force with energy and work done. If you use a lever such as a crow bar, what you are doing is magnifying the force used but at the same time decreasing the available movement. What a lever does not do in any way is change the available work/energy. The work done at both ends of the levers (not counting any friction losses, etc.) (Work=ForcexDistance) is the same, all that happens is the lever converts the distance moved and hence the available force.

There is a good overview of the relationship between force, work, torque and energy here:
http://auto.howstuffworks.com/auto-parts/towing/towing-capacity/information/fpte.htm

If you put a motor designed to generate torque force with very little electricity with a motor designed to generate electricity from torque force, free energy, you will not generate any free energy whatsoever, you will just lose more energy in conversion to to the inherent losses in the dynamo and there are many failed attempts at trying to link a dynamo back to a motor to generate free energy. The second law of Thermodynamics covers this particular issue and you can also do research on over-unity machines, but make sure you look at genuine scientific sites, not pseudo-science:

Thanks for your feedback. I believe this can be done. I am on my 4th design,it's easy to not get it right!. But my gut builder blood tells me this will work but new innovative thinking must be used to find the right design.

I would like to see the "failed attempt" designs you are talking about, if you can help me with a link I'd be thankful.

I came here to meet someone that could help me with designing and sizing components to build a bootstrap capacitor to drive my power mosfets, if you know of someone willing to work with a mad scientist like me please let me know, for now, back to the lab! Come on Egor! Ha, ha, ha ha !

Thanks again!
There's a good paper on bootstrap capacitors here:
http://www.irf.com/technical-info/designtp/dt99-7.pdf

With reference to http://en.wikipedia.org/wiki/Electric_motor "efficiency for a brushless electric motor, of up to 96.5% was reported". From a quick search, this seems to be a top level of efficiency for a motor, typical motor have less with 90% being a real world good result. Dynamoes/generators exhibit similar efficiencies.

By putting two systems together, you will get total efficiency in the system of 96.5%x96.5% (assuming best recorded efficiencies) which is 93% efficiency of the system. This means that you would need to input 7% power to keep the system running continuously. There would be no power generated within the system.

There are no end of devices like this being shown running on YouTube, all guaranteeing that they work, but if they did, do you really think that there wouldn't be one in your car now? Despite the conspiracy theorists, it would be impossible to contain such groundbreaking and revolutionary technology. Unfortunately, the reason no over-unity devices or perpetual motion machines have ever been demonstrated to work is because they are impossible. See here for further info and leads; http://en.wikipedia.org/wiki/Perpetual_motion

I am not looking for a good paper on bootstrap capacitors. I need a person with many years of experience to help engineer a circuit to run my motor. I have found the basic needs to build a circuit that works good, but an expert could build it way better!

The brush-less electric motor is a conventional motor design, with the motor built tight to the shaft,brush-less yes,but it does not employ leverage. Find a better example, something, , ,unconventional!

Sept 22nd 2011? This must be a video from the future! :^)
Masternot (author)  Ranie-K3 years ago
Ha, ha yes I was testing you, you are too sharp it was 2010 , good to see you were paying attention!

I would recommend caution with the patent office. There might be something we don't see but from that video I gather this is a form of direct drive hub motor with mechanical coil triggering. Electronic triggered versions of this concept (although admittedly the inside functioning may vary) are common in high end rotary actuators.
Masternot (author)  mathieulj3 years ago
Yes I think the patent would be more on the design of the motor drive, The electronic triggering is use in other applications, I just lack the full knowlede to size and fit the components. I like things that work simple!
