ALTERNATOR

>induction is.......
N-S Field must be parallel to wire-segment.

If the Magnets axially rotated in a circular path over axially wound coil.........
Equivalent to coil-winding remaining still and rotating the 4 magnets axially, wire always parallel to the axially rotating N-S poles.
What V-out should I expect?

Is there a general "OPTIMISATION-RATIO" rule of thumb to how thick & long the magnets should be verses the coil+former thickness?
I'd like the magnet-ring outer dimeter to be 100mm.

Can anyone help with this?

I'd say no output at all. If I understand what your doing. Magnetic induction works by the poles going past the coil, alternating between N and S. What I see in your presentation is both poles rotating around the coil, no alternating poles at all. If I'm wrong about my explanation of you thoughts please explain it better.

>poles going past the coil?
You're saying N-S poles line up temporarily to induce a voltage across a wire-segment, then its "removed" completely for that stored energy to be released?
Then same is done in the opposite direction?
This is an intermittent circuit, makes no attempt at full duty-cycle per rotation.
this is a relaxation circuit.

>rotating both poles around the coil
every 360degree loop segment of winding has +N -S +N -S....
with 90degree turn is altered to -S +N -S +N.... with 90degree turn is altered to +N -S +N -S.... with90degree turn is altered to -S +N -S +N....
Every individual 90degree wire-segment sees a +N -S, then -S +N, then +N -S, then -S +N.....
The N-S field exposing every single wire-segment on the coil is continually changing, therefore a continually changing voltage will be induced across that exposed wire-segment.

wire-segment will have the N-S induced on it, when rotation changes to S-N then thats what will be induced on it.
HOW can a parallel wire-segment not get induced by a magnetic-field thats always changing?

If I run a magnet along a length of parallel-wire, then it induces onto the bit of wire I'm upto and the previously induced wire dissipates its energy.
It would appear as though a single point of inducted energy was on the wire, and I dragged it along the wire's length.
How is my design not a pump?

 

Thanks to shortbus for his input
I will spent time changing the design to keep Full-Duty-Cycle operation BUT focus entirely on altering winding &/or magnet to ensure poles going past the parallel winding as suggested.
I'll be back to update when done.
cheers.

 

An Alternator doesn't use magnets , it uses a magnetic field using a Rotating coil inside a fixed coil ...Dynamos use magnets...

I've no idea what you think your design will do but that type of magnet array is used in some brush-less motors with proper field coils that cut the flux lines properly.

No, thats more of the same intermittent rotation duty-cycle I want to eliminate.
I'm now re-penciling.

Intermittent rotation duty-cycle? What type of generator magnetic design requirement is that?

Look at the magnetic flux fields lines and how they cross the induction coils during rotation.

To increase the force on the wire you can:

• increase the current
• increase the magnetic field strength
• ensure the current is exactly perpendicular to the magnetic field lines.

If that is so why do the call the PM alternators in motorcycle engines alternators? They produce AC that is then rectified to DC and regulated.

" A dynamo is an electrical generator that creates direct current using a commutator. " From - https://en.wikipedia.org/wiki/Dynamo Unless dynamo is one of those words that means something else in UK english vs US english. Like "boot" vs "trunk".

 

HOW can a parallel wire-segment not get induced by a magnetic-field thats always changing?

That will work with two wires parallel if one has an AC voltage on it, that is the basics of a transformer. But it doesn't work like that with a permanent magnet running along a parallel wire. At most it will only make an "eddy current" got a useful voltage.

 

>Ode to reflective ponderings..........
Yeh, not gonna work.
You can't excite others to fix what they don't yet realize is broken..
As lame ass boring as it will be, you will have to come up with the solution yourself.
Reinvent it from scratch.
Don't ask me how, I'm as pissed off about it as you.
just stop larping, its wasting time.
Yes, it sux.

>"the problem"

The electrical yield is still orders of magnitude less than what the new motor drives. The 2 sections combined looks like a flagpole with most volume unused.

A radically different geometry is needed.

>radically different geometry

There is no alternate to how it is wired.
Also, the old way does make a 3phase output easier, and will always be proffered by industry.
The only solution to our flag-pole problem is a wider diameter.

 

does left-to-right passing a magnet perpendicular past a parallel wire induce it?

Does right-to-left matter?

It's your design, you show us, with some simple math, of how it works.

I don't know what it is about you guys coming around to ask questions that should have been answered in junior high school science class. I seems like maybe it was but you didn't pay attention, but that's just a guess on my part.

Like Dana Scully said to Mulder, "the truth is out there".

>" does left-to-right passing a magnet perpendicular past a parallel wire induce it?"

Device-equiv = left-right, then left-right with magnets poles-flipped, then flip-poles & left-right, again......
continuously..

I'm sure I've stated it correct
To my understanding it should work.

Won't uploading design inhibit patent, if it was original?
*really sorry for being annoyance.

If you're asking for profession advice on a possible patent then don't we deserve a cut? Times are hard and money's losing value.
