Counter Emf Neutralizing Pulse Motor

[SkyWatcher]

Hi folks, Yet again another idea. Though this one I've actually made some simple tests and found that it may have promise.

I seem to recall that Garry Stanley may have had a similar idea, though I'd have to dig around in my archives to find his posts and see how similar it is.

tests were with 2 air coils, one on top of the other, one layer each and one coil is wound the opposite direction of the other coil.
So I powered this coil arrangement and found that with the diode the magnetic field from 3.5 volts input is just about the same as without the diode, diode voltage drop accounting for that.
I used a large stack of neo magnets for gauging the field strength and I also used this stack to observe induced voltage when the diode is in the circuit.
So in repulsion mode, I observed the voltage on a dmm and found there to be virtually 0 induced voltage and what little i did see was from me removing the neo magnets from coil in abnormal ways that would not occur on normal pulse motor setup.
Let me know what you folks think of this and it is fairly simple to try out, maybe someone could try it, as I will be setting it up soon to try in pulse motor, thanks.

Hi again folks, So let me summarize what I feel is occurring in this setup.

When say using repulsion mode, when the neo magnet is departing the air coil and we then pulse the series coil arrangement to repel, this operates as it normally would repelling the neo magnet away, with a tad bit less force due to diode voltage drop.
Now at the same time it's repelling, we would have the typical counter emf/back emf and this normally would counteract our voltage input and reduce the voltage within the drive coils and so reduce the available magnetic field.

Though what happens when we have the other coil wound in the opposite direction and we place a diode between those two coils.
What happens is, is that one coils polarity that faces the magnet is say positive and the other coil polarity negative at magnet face.
And when these coils have induced voltage from the departing magnet, it is short circuited by the diode and no voltage and therefore current is allowed to make a circuit with the input battery. The result of all this is, is that we can still power the coil arrangement to repel our rotor magnets and avoid or neutralize the destructive counter/back emf.
I hope this helps explain what i see happening and I can't wait to try it on a pulse motor to see the benefit.

Hi folks, this is the coil design I used to test this idea so far. Like I said it has air coils, 1 layer each and is 24 gauge.
This isn't difficult to try, I really think someone should look at this, at the least to tell me I'm missing something or not.

Hi folks, ok i just realized that a sinlge coil with diode does the same thing and even a simple transistor does the same thing, prevents coil induced counter emf from making a voltage connection with input battery.
I think the site 'totally amped' mentioned this as well now that i think about it.

So the question I am now asking you folks is.
Does a bipolar transistor or using a diode, block the coil/magnet induced voltage from establishing a current and thereby prevent our input voltage from being reduced or not? Thanks in advance for any help on thinking this matter through.

Hi folks, I know this thread I started may seem elementary and maybe I'm just confused about counter emf caused by permanent magnet induction passing a coil and how it reduces our input voltage which then reduces the current and magnetic field that can be created in a pulse motor coil.
Though, what I can't understand and I hope someone can help me understand this, is that if you place a diode in series with a coil and pass a magnet by this coil and check to see if the coil is in repulsion to the magnet by inputting a small voltage.
Why does a volt meter not show any voltage when manually pulling the magnet away, as this is when we would be applying our input from our battery to repel the magnet.
This shows that no counter emf or induced voltage can interfere with our input voltage, since the diode blocks any voltage/current from getting back to our input battery.
If I'm not perceiving this correctly, can someone please offer there thoughts on this, thanks.

Hi SkyWatcher
I don't know if what you are showing works or not,must try it!!
but,I can't see what gain there is in not having bemf,I can see a gain in having an increase in bemf.

Skywatcher,
because you are to slow, lol. I did try that too, to get some Voltage out from a Coil by moving a Magnet beside, but i close twisted my arm on that.

Well actually its a matter of inducting, like, move a Magnet over a Copper or Alluminium plate, you need a big Plate to induce any Voltage, you may can make easier Amperage. A Coil has not very much surface, where it has a nice Induction area like a Plate.
But you may can repat it with a Core inside the Coil or any Iron, that should help a bit, to show something on your Meter.

I am new here. I will learn much knowledge from everyone. Thanks!
Nice to meet you

Hi and then.

Hi petersone, thanks for the reply. The idea is simply a diode in series with a motor pulse coil.
And the only question I'm having is does the coils induced voltage from the magnet departing our motor coil while being pulsed in repulsion generate a current against the input voltage to impede the battery input or does the diode actually block that from occurring, that is what I am questioning.
Or is the coil just like a battery being put in its place or not.
