Magnetic flux motor just patented that creates it's own electricity!

I'm glad someone else is attempting to build this. It seems like it has potential. Either way, I'm not getting my hopes up. I'm kinda taking a stab at it too. Although I'm just using the thin sheets of metal you can get from lowes, not electric steel. I had some time to kill but should have it done in a couple weeks or so. I'm hoping there are more people attempting to build also.


Can't remember how to embed photo's in the post itself so i'll just add it as an attachment. <edit> Never mind it did it automagicly.

Hi Drak,
As long as it wasn't stainless steel, I think it should function like electrical grades basically but with higher loss. However at the apparent frequency and induction, likely be unnoticed. Nice job on the stator rounds. Wonder how you cut those laminations. Nice.

I can't make out the magnet arrangement in the rotor arms. Have you s photo of the magnet alone?

Following with interest. Have you ideas for test fixture?

That looks awesome mate. How did you cut the sheets? Thanks for sharing. Nice work.

Yeah, stainless steel doesn't even stick to magnets, at least the little bit that I have laying around. The loss is what I'm worried about. Even if this thing doesn't work I can't say Mike's device doesn't work because I didn't use the same steel he used. Your right the induction shouldn't be a problem because this thing would never run fast enough to make a difference. (actually I hope I'm wrong about that)

Nice job on the stator rounds. Wonder how you cut those laminations. Nice.

Thank you, I try to copy as close as I can and give it my best when I do try to copy something. The laminations were cut using a cnc I built that I copied from Strange Garage's youtube channel here https://www.youtube.com/watch?v=KmQWsWh0Zsk
That was the first time I ever cut steel, and I will tell you this: I DO NOT LIKE CUTTING STEEL. I don't think that machine was designed for cutting steel and struggled through every piece. I mean its a strong machine but every piece I cut was an adventure mainly because my speeds and feeds were not correct. I only bought 2 steel cutting bits and by the end of it one bit was broken and the other wouldn't cut hot butter. I think my spindle speed was way too high. I could rant about that forever but you get the jist.

I'll post more photos below

Yes, I plan to put the same size diameter pullys on the input and output shaft and use weights, like in Willy's twist device setup. If it is able to lift more then it takes on the input then it should called a success. At that point it would be just a matter of putting a third shaft parallel to the input/output shafts and connecting a belt or chain from the output shaft to the third shaft and from the input shaft to the third shaft, then put a slight torque on the input shaft, lock it in place, let go, then run out of the room. I'm not getting my hopes up though, over the years of building sh_t I've learned better. I might order more magnets, those things I'm using now have been sitting around here for years and I don't know what grade they are.

That looks awesome mate. How did you cut the sheets? Thanks for sharing. Nice work.

Thanks! See above and below.


I designed the whole thing in FreeCAD. Took me about a week to design it. I used the spread sheet in FreeCAD so I could change dimensions on the fly. FreeCAD can also generate the G-Code for the CNC. <edit to add> I know in the picture of the cad the strators are not twistd for each phase, for the life of me I could not figure out how to get freecad to twist the strators as it goes back, but the holes are there to do that after the pieces were cut.

Looks great Drak.
Suggestion. Electrical grade steels typically use core plate. This is a thin layer on the surface, both sides, although only one side would be necessary. This core plate is an insulating film. You might spray a light coat of varnish. This would go a long way to eliminate eddy currents and avoid about half of the core loss. You'll get a certain amount of interlamination resistance from the natural surface oxidation and flatness/compression imperfections which might be enough. But if you entertain high speed trials, I'd coat it.
Cool project.

OMG I completly forgot about that, I remember that being discussed back on Jack Hildenbrand thread. Thank you so much. I think they were talking about using news paper and stuff. This is what I have on hand will any of these do, or should I specifically buy varnish. If so what brand?


If you have any other suggestions I'm all ears.
