Electric Motor Secrets

[Peter Lindemann]

Standard Configuration

I kept thinking about electric motors and pulse motors in general and why they were made the way they are. Dr. lindemann's motor kept me asking "why aren't things done this or that way". To keep the story short. The attached image shows a simple idea that can be used similarly to the Lindemann motor. There's only one rotor arm shown for convenience.

The only difference and advantage? is that it uses a C core and permanent magnet. The air gap can be "closed" quite "easily" as you don't need advanced machining to make the air gap arbitrary small, between the core and the PM, because it's flat. Making a very strong magnetic loop. The other difference is obviously the PM's. Will this have any big differnce? Who knows.

The motor has also the advantage of adding more cores without too much trouble.

I also might add that Thane was part of the inspiration by looking at his flywheel that has PM sticked on it .

Broli,

Thanks for your idea. I know it might be difficult to see, but your image produces a system with standard back EMF operation, assuring classical COP<1 behavior. The problem is the direct relationship between the permanent magnets on the rotor and the electromagnet on the stator. If the rotor is turned through the stator in your design, it functions like a generator. This IS the problem. In my motors, turning the rotor does not generate any EMFs in the stator.

Keep thinking about these things. You will understand it eventually. It only took me 20 years to get it straight in my mind. You'll get it sooner then that.

Lindemann. Have you ever thought of combining your work with Thane's work? The results can be staggering. On one hand you have your no back emf motor and on the other hand a coil setup that causes the rotor to accelerate spontaneously. Poor Lenz is being violated twice .

Broli,
Here is something to consider. Lindermann's motor doesn't produce Back EMF. Because there are no coils rotating across magnets or no magnets rotating across any coils. The Iron rotor is attracted to the coils when they are pulsed, but the pulse is turned off before the rotor can reach lockup. But if I'm correct the coils produce a self-induced EMF of the good sort. Because, There is no magnetical connection between the coil and iron rotor. The rotor torque and speed is unaffected by the coils self-induced EMF, which can be harvested to recharge batteries. Hey, is magnetical a new word? Lindermann can have the credit for his motor(good job Peter), I want credit for magnetical being new and unusual. Be it on public record heretofore!!

Ecklin Brown Generator

I'm looking at Practical Guide to Free-Energy Devices - Chapter 1

About half way down the page is an explanation of this image of the design of the Ecklin Brown generator.

What struck me was whereas the Lindemann motor uses pulses of electric current to produce a magnetic field, the Ecklin Brown generator uses *interruptions* of magnetic field to produce electricity. Searching for a "reciprocal" myself I would never have guessed this in a million years..

In any case this looks to be the answer to my question about how a generator would be designed. Earlier in the thread Peter mentioned a lot of Ecklin's designs didn't work, but is the idea of interrupting and allowing a magnetic field to reestablish itself past a coil on the right track?

Any new progress?

Hi Jetijs,
I was just wondering if you've made any new progress with your motor. I'm still gathering material for my motor, and I'm going to use your circuit to control my motor, if you don't mind. I'm about 85% complete and will post some pics and video if possible when I am complete. Great work with your motor!!! I hope you and Peter continue to provide input and inspiration to this thread!!

Hi Archer Newlun
I was just thinking about this thread and that no one has posted in it for a long time. What a coincidence

I am now working on a new design of this motor that will have 100% ON time and no inertial movement. It will have a mosfet for each coil thus making it more powerful and it will have a timing adjustment system that will allow me to adjust timing on the fly. I just thought that if I am working on this, I might as well give it the best try I can. I already had my stator cores made, but those guys who did the lathe work, messed everything up. So I had to get new plates, get them laser cut, which took about a month and now I need to glue them all together again. That is why this thread is so quite for all this time. The new design will basically be two attraction motors coupled together with offset timing so that when one motor rests, other does the work. The stator plates now are made so that I can use prewound coils as Lighty suggested. Here is a picture of how this might look like:

This one has two flywheels, but since the ON time will be 100%, I don't think that I need them. Also the timing system will be a bit different, but you're get the idea.

I am glad that someone else is also working on this. Could you maybe tell me more about your setup? What will the motor look like? What materials will you be using, do you have any pictures?

Thank you
Jetijs

Motor Setup

@jetijs

Sorry, I don't have pics yet, but I will try to get some up soon. I'm still waiting on some more electrical steel to come in, and after that I'm going to get my stator cut out of it. I actually was thinking of a similar setup as the one you just showed me. I was going to design a dual attraction motor setup also. What program do you use to draw up your designs? I'm glad that someone is still working on this project other than me!!!
Let me know if you need any parts, I might be able to help!

[Jetijs]

I am using solidworks to make my CAD drawings. I find it the most easy software to make 3d objects.
I am glad to hear that your design will be similar to mine, I had this idea almost year ago when I made my second attraction motor. The 100% ON time should provide excellent torque and it will also be self starting
Keep us updated on your work
Thanks,
Jetijs

Solidworks

Is solidworks freeware? Where can I get it? I would like to use it to create my drawing so I can give you an Idea of what my motor will look like. I want to make my motor casing cylindrical in shape. I will have (2) 4-rotors offset by 90 degrees just like you motor. I want to make the motor as compact as possible. I also want to be able to adjust speed of motor so my timing system has to be adjustible. I was going to wait untill after the New Year to start working on my motor again, but I have a burst of inspiration to try and get something done! Thanks jetijs

[Jetijs]

Unfortunately solidworks is not a freeware and is rather expensive software (several thousands dollars). I just have access to a computer that has this software installed.
Also, are you sure about 90 degree? Don;t you mean 45 degree offset?

[Archer Newlun]

Yes, Sorry I was thinking about (2) 2-rotor design. It will have a 45 degree offset.

[Archer Newlun]

I have AutoCAD at my work, but I never used it. I will give it a try this week. Hopefully I will be able to show some drawings of my motor.

Stator windings

Hi,

I am wrapping coils for my stator this week. The design is the same as Jetijs version 2, but the stators dont flare out at the end, they are just straight. What can you suggest. I am doing the following.

1.Have other people to help.

2.Put adhesive backed mylar, so they wire coating does wear

3.Have made a few tools for getting the coils on straight and tight as I wind, and dont damage the coating.

I want to know how I can secure the coils as tight as possible. What I want is to get a coil in position and basically super glue it in place, but super glue, apparently, doesn't stick to the mylar. I could use some help on this. Ill ask others at my school as well for suggestions.


I'll be presenting my pictures sometime soon, but I could use the suggestions sooner.

Hi Chris
I would suggest to grind round all the sharp edges of the core so that the wire can not be damaged in the winding process. Also after grinding, coat the grinded area with some epoxy resin of some coats of varnish. The sharp edges for me was the biggest problem that made the winding process twice as long. Also make sure if you can not wind your coils outside of the stator and put them in the stator later. This would make things much easier. You already have a pole shape suited for this. To secure the coils in place you can use some epoxy or just a hot glue gun.
Good luck!

[broli]

I consider myself now much wiser since my last post here . So I'm going to drop another suggestion.

I have searched this thread for something similar but I didn't find it. (maybe I haven't looked to good). But I think most know the principle in the picture. You use a permanent magnet and a coil. The coil serves as a path switcher for the PM. In the off state the permanent choses the smallest loop being through the coil but when the coil turns on the PM switches to the longer path through the rotor. I think the main guys behind this idea are Flynn and Hilden-Brand.

So this is a rather small addition (on paper) that could bring interesting results. That is besides the fact of recollecting the collapsing field you might have a substantial increase in torque which can lead to other ways to extract energy from that torque.
