Hi All,
Thanks for being here.
I want to learn best specs for a coil that will be one of several for a pulse motor.
I've begun with a Bedini type bike wheel arrangement and 1 air core coil.
The plan is for 16 coils and input of 1000W @48VDC.
Mosfet triggered by hall effect device sensing each of 16 ceramic8 magnets.

My non engineering math says at 48vdc at 1000w, I would want about 1.3A per pulse.
Harvesting the flyback for charging a battery bank of 48v is the objective.

I'm concerned with proper coil specs at present and will enquire about other issues later.
The bike wheel .pdf is accurately scaled and the bike wheel is 20"D.
The coil form is 3.25"H, core .75"D, Flanges 3"W.
The magnet ends are 3/8"thick and .875"W

The circuit .pdf is a basic functional driver that I'm using for initial testing. It works fine.

I've been running with an 18Awg single strand coil at 6-24V. The coil is 2.6ohms.
I suspect that too much heat at 48v would be destructive.

How do I go about arriving at best coil specs for the application?

Thanks for your considerable help,
Donald

 

Is this for some sort of Perpetual Motion Machine?

Are you ready to pounce and trash any answer but no?
My interest for posting is to learn how to arrive at desired coil for the application.
1.3A pulses at 48vdc into an aircore coil that the mosfet will be happy with.
Thanks,
Donald

Thanks, that tells me all I need to know.

 

Evidently You have run into similar responses ......
Have You learned anything yet ?

A Flyback-Spike is NOT "Free-Energy",
the Magnetic-Field that the Spike comes from had to be generated in the first place,
this takes POWER.

Anytime Power is changed from one form to another, there will be losses.
In your project, the losses are absurdly massive.

All of the veterans on this Forum have looked at what You think You are "discovering",
possibly multiple-versions, multiple-times,
and all have found that none of them work,
not even part-way, not even a little bit.

This subject has been thrashed to a bloody-pulp.
We haven't been given the technology yet.

While some call this perpetual motion it is also called over unity. Doesn't work and isn't allowed on the forum.

 

Please have mercy on me.
I did not post for help with an over unity device or perpetual motion machine.
I have charged batteries with flyback spikes for years but that is not why I'm posting.

If you are not willing to offer advice with coil design as I have requested then why not?
You can twist my request into anything you wan,t how ever
I'm 80yrs old and desiring to reduce my ignorance regarding coil design specs.
No assistance available, PTL.

What You are doing is literally a waste of time.

Free Coil designing programs are all over the Internet,
I've used and bookmarked several of them.

The rules and Math-Formulas were well established and codified many decades ago.
They still work, nothing has changed.

If You have a particular project that You need help with figuring out,
there are plenty of very smart, and highly experienced
people here offering all kinds of help every day.

Air-Cored-Coils have a very limited practical application range,
they are normally only used for high-Frequency Circuit Tuning.

Magnetic-Fields are normally concentrated by some sort of Metallic-Core, or structure,
which then makes them much more efficient and useful.

Exactly what you asked:

https://coil32.net

Input:
Former diameter D: 30 mm
Winding length l: 10 mm
Thickness of the coil c: 3.1 mm
DC resistance of the coil Rdc: 39.6 Ohm
Wire diameter with insulation k: 0.5 mm


Result:
Number of turns of the coil N = 119...159
Inductance L = 468.345...715.238 microH

 

Thank you Danko,
You are a great help.
Some need a checkup from the spirit up.
Now I want to go to https://coil32.net and get functional with it.
Thanks again,
Donald

I don't believe in spirits or magical over-unity machines. We all know what Bedini type means.

I’m sorry but “free energy” is not a permitted topic on AAC.
