A1Mo-Gen: Tesla's Gift "The Electromagnetic Reactor"

[DadHav]

I stated the Singular Coils = A1MoGen ...Guildline Spec = All coils are the same size as the magnet.

The reason why I made the spec is... Why would I want a coil in an area without a magnet!? I want use as much of the concentrated magnetic force as possible.

John, you like to wrap the armature = 1pole with a neodymium magnets per armature... It's the same principal but I work with brushed DC Motor that are CHEAP and available anywhere on the planet.

On the 5pole, wrapping the complete armature/1pole completely is great. That motor will have the high RPMs and serious torque... Now, we have to take into consideration the size of the magnet. The bigger the magnet, the less advantageous to have one armature wrap because of the size of the brushes. On most DC motors, one brush is connected to two commutator segment at any given time. Yes there are some that have wider brushes but let's stick to what most of us currently have, brushes are about the size of one commutator segment.

Mark, the 12pole/2 magnet motors are absolutely perfect for anyone on the planet! You can do everything that I have been saying on my thread with it. Everything!

Mark, keep you foot on that snakes neck. It tries anything to get a way when it's wrong. But keep in mind, its going to bit you as much as it can later.

Richie you are correct about my motor winding preference but I'm not suggesting it would work in the asymmetric motor. I haven't experimented enough to make a suggestion towards using it. I think you will find that in brushed motors as well as brushless the more magnets you have the slower and stronger the motor will be and with less magnets the faster. Also single wound stator legs or armature slots will be a slow strong motor while combining stator legs and or armature slots, even if they are not over lapping will speed up the motor and give less power. Over lapping windings increase the KV or RPM's even further. That's a pretty general statement and I'm sure many here can shoot holes in it but it's something to consider if you're looking for answers as to how your performance is. Raul could probably technicalize what I said a little better. I don't think technicalize is a word but I like it.

It works perfectly well. Look at Gary's 5pole battle results. Its a singular coil one armature/1pole=AN3. I know that motor has some serious TORQUE ! And still had the RPMs! it just needs fine tuning.

I haven't experimented enough to make a suggestion towards using it.

Stop being modest! You know what your doing.

Your statement makes sense to me... Now, with the singular coils and extra brushes, I'm trying to level the playing field.

John,

First of all, don't think about that clown when you make a comment! Speak your mind freely here without any worry. I like to learn and express ideas openly that are relevant. Take a load off your feet! Relax as much as you need.


He can't bother you here. We both have been warned. Plus, I can have all his posts deleted!


Secondly, there are a lot of people that are rookies and people from all over the world. I write simple and easy for everyone to understand the main topic, Singular Coils = A1MoGen... with Extra brushes.

There are three images in this sequence showing the 'sweep' of P1 comm across the brush. The point I'm laboring is the leading edge of P1 energising the coils and the trailing edge of P1 before it disconnects from the brush.


Key points -

The OEM setting for the brush is the same size as one commutator segment

Hey Mark, Make sure you let me know if you make a video about what you're talking about. Maybe I can help you figure out a few things or refine your test. Cap dump circuits are very popular with pulse circuit experiments and there are many techniques. I've never experimented with anything on the level of an Imperial motor though. I might have something to offer on a small scale to help people experiment and understand on an inexpensive basis. I have some small PWM modules on their way and what's unique about them is they are only about $3.00 US and they are a low frequency device that can have a frequency setting as low as 15 seconds if necessary. The output transistor should be capable of driving an FET for cap dumping so it could be fun for cheap. The closest thing I'm having success with is my brushless motor/generators and will try the module on them. They probably will have a similar effect as the brushed motor/generators being made here. Since these are individually wrapped stator legs they can have 6 coils for prime mover and 6 for generator. Now I could be wrong but the effect is similar between both (maybe) . Even though the generator coil is completely isolated from the generator coil it has a transformer effect from the motor coil. When I look at a scope trace I see a smooth sign wave from the transformer effect and then a high voltage spike. After rectification I can watch the capacitor charge and it charges very rapidly from the transformer voltage then very slowly charges the capacitor to the additional high voltage of the radiant spike. When you get into it further you might see nearly the same thing. Well wait a minute. Maybe I can hook the dump circuit to the little 5 pole motor just for fun. I have to think about that. If you are getting higher voltage than your battery from a generator coil that isn't in series with the motor coil then that might be special and work that way. I would have to run the series setup to get above input voltage. OK now I'm just thinking out loud. I'll let you know if I get anywhere.

Thank you John. That was mostly outside of my comfort zone, but by the time I'm finishing off this series of tests I will be moving into that area and will need to get to grips with it.

I have one more planned motor wind with testing before I put the winner back into the modified scooter (bigger back belt cog) to see how it performs. The outcome of that will translate into my 12" 120 tooth rear wheel project which still requires a platform to mount it on...another work in progress.

And those cheap PWM's sound like a real find.

Please keep the thread updated with your results.

Happy Hunting

For the simple Brushed DC motor we are using, please look at these inexpensive and well built OEM style PWM controllers:

Just the way I said it before the argument about singular coils!.. I didn't deserve the BS from UFO. He needs to apologize to Mark, myself, administrators and all for his huge misunderstanding!

Good to know Midaz. But blowing up a few $3 PWM's sounds like a better learning curve.

I do like the idea of their controller with regen, but I think I want to keep it simple at the beginning.

Singular Coils = A1MoGen

5 is the magic # for motoring only


The reason I said that 5 is the magic number for motoring only is... You can add extra brushes!

The goal is to increase the overall performance of your brushed DC motor without creating magnetic drag...
While working with what you have available, cheaply and effectively! Keeping it simple as possible for maximum enjoyment.


Take the number of poles and divide it by the number of magnets. If that number is 5 or greater, you can add more of the same readily available OEM brushes to your already existing brushed DC motor!:thumbsup:

Example. 12 pole, 2 magnet, brushes the same size as 1 comm segment.
12 divided by 2 = 6. .... 6 is more than 5. You can add extra brushes.


Why extra brushes?

Advantages

1.) you at the very minimum you double coils to power the load
2.) double the "throw out" angles = more RPMs
3.) can use a thinner wire to lower the amps draw
4.) more coils being powered = more torque
It's just a simple DC motor.

i suppose you could just drill into the brush board, and fit extra units, similar to these :

INDESIT WIB111 WIB111UK Washing Machine MOTOR CARBON BRUSHES x 2 | eBay

1 disadvantage of more brushes, would be, it forces you to use smaller coils, which means less high-end power.

on the flipside, as its pinging drive more often, it should be able to maintain the low-end power better.

i have no idea how that will effect the driving characteristics, but my best guess is... it will restrict your top speed.

if thats the case, then maybe changing gear ratio's is the answer, to level things out.

who knows tho, the only way to find out is to test it on your bike in the real world.

When thinking about the Singular Coils = A1MoGen with extra brushes

First Guildline Spec is... All Coils are the same size as the Magnent

That first spec is flexible. It allows you to do what you think is best for YOUR needs.




For example: 12pole. 2 magnet(size of 5poles wide), brushes (size of one comm segment)
Magic #5 = extra brushes for motoring only works for this example motor!

You either want Max RPMs or max torque... I say, I want it all or as much as I can get.

Keep to the first Guildline Spec....

Option 1: singular coils are the same size as the magnet, 5poles wide, will give you max RPMs

Option 2: each armature pole is wrapped/wind completely with one singular coil...It give you max coil magnetic field strength (DADhav , see, your style is all good too! )

*When you add extra brush you get more torque and more RPMs with both options.



*You may be thinking, "That will increase power consumption!?"*

Of course! You have to pay to play.

Or

Use thinner wire ......

Option 3: motor can be run in series.



Conclusion:

If you want to Hot Rod at full power, extra brushes add to the fun

If you want to drive all day to a nice location, thinner wire and extra brushes give you a higher top end for highway speeds.

Are my thoughts, my fantasy or can it be done... Singular Coils with extra brushes IS a real game changer!

[grounded]

ignore my earlier comment : " it forces you to use smaller coils "

the design wouldnt need changing would it.
i havent barely slept for the last 4 years, so im not really with it.
it should work ok.
it will be firing all over the place tho, left, right and centre - pow,pow,pow sparks camera action lightning smoke and fire, haha

wouldnt it suck alot of juice like that ? firing twice as often, youll have twice the performance, and twice the drain maybe ?

A1MoGen = Singular Coils with Extra Brushes

Motoring only & the importance of #5

Published on May 17, 2015
[VIDEO]https://m.youtube.com/watch?v=9KWvDSNqi-8[/VIDEO]

When choosing a Brushed DC motor, look of a motor that has the "Magic" #5 or greater.

Examples: 20/4 = 5 ..... 12/2 = 6

Number of poles divided by the number of magnets. If the number is 5 or greater.... You can add extra brushes!!!

I do this for people that my not have access to expert tools! Keep it simple!

[grounded]

i missed the " pay to play " .... im dopey

i dont know if its possible to do, but maybe fitting bridge rectifiers on the 4 extra channels, so the regen-energy is pumped back into the 4 feed lines, for motor assist ?

not sure if its possible, without straining the motor tho.

ive tried charging from the output lines on mine, and it slows the motor speed down.

that was charging a DC battery with the AC that was coming out tho, which your not supposed to do.

i havent tried a rectifier on the line, to convert it to dc

[grounded]

Diode bridge - Wikipedia, the free encyclopedia

apparenty each of the 4 diodes that make up the rectifier circuit, steal a bit of power in operation, about 1 volt each roughly, so your looking at a 4v loss of output per rectified channel, which should be minor when the motors upto speed, and kicking out double or treble figures.

but like i said before, im not sure if it will work, im just guessing.

ive seen other people with the bedini wheels do a similar thing tho, so its not impossible, with the right circuit.

my knowledge on electronics and circuits is pretty sh1t. i wish i knew more.
