Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

Stefan,

This forum is about trying to replicate Mike's variation of John's Window Motor, or John's Window Motor directly.  I really think bringing your Newman Motor model into this group is a distraction, as well as being completely irrelevant.

I wish all of your Newman Motor posts could be removed from the forum, scope shots and all!

Hello Peter and ALL,
I am not using the Newman coil in a Newman configuration.
I am now using this coil just as an Replacement for the Window-Coil.
I just want to see, if it also works with such a normal coil.

ALso as you could see, my open circuit voltage at the coil has about the same voltage output waveform as the Mike motor modification, although it is much higher, cause I have more windings...

So I think these are valid tests...
I don?t use any Newman things with it, just the coil
and the magnet inside the coil.

I hope this makes it all clear.
Please just forget the word "Newman" about it...


Regards, Stefan.

Re: placing magnets

With my juicer motor, I found the easy way to position the magnets without having them move and stick together is to put a thin steel plate over the top of the rotor.  The magnets stick to that and I can slide them to the proper position. Then I tighten the straps and peel off the steel plate.  Before I did that the magnets slid together and made it very hard to position them.  I still have two magnets stuck together and I can't get them apart [ :-( ] .  I think I'll have to make a wooden tool to separage them.  I think I need a whole set of non-magnetic tools if I continue with this research.

What about winding a coil around the Space,where the Magnets stick together
And than suply this coil with a dc ,to create a magnetic field,that works against the Field that both Magnets use to be kombined.?
It might be helpful to separate them.

however   good luck

I have collected most of the items required and have started to build a window motor as close as possible to the instructions gleaned from Mike. (Pics attached)

The wire for coils 1 & 3 is 0.25mm dia and coil 2 is 0.315mm. Each coil has a total resistance of 45 ohms, wound trifilar with the extra coil 2 length divided equally at the beginning and end . Coil 2 is 417 turns and Coils 1 & 3 are 263 turns.

The magnets are ferrite 150mm x 12mm x 6mm.

The spindle is mounted on roller bearings removed from an old VCR guide roller and spins quite freely, at least 30 seconds with a hand spin.

Now this is where I must show my ignorance of electronics:

Applying 12 VDC to any of the coils causes the rotor to jiggle around, but not to rotate.
Should it be able to spin with a constant current applied, or does it need to be switched on and off at the appropriate point.?

Checking the charging from coil 2 with a hand spin, shows around 2.5V.

I?m looking for some guidance here. Are there any formulas regarding the ratio of coil size and magnet strength etc. Will the coil/magnet arrangement be right when coil 2 can generate around 6V DC at the sort of speed Mike was showing in his video?

My next step was to try a bigger coil, and perhaps some stronger magnets, but I don?t really want to waste my time if someone is prepared to share their experience.


Thanks in advance

SPP-48
nice mechanical setup,
Do you use hall ic, transistors circuit?

i want to build window motor too, but need coils&mechanic parts. i bought electronic
parts.Hall ic is : 3119U (output 25mA) with datasheet, but i didnt find 3020 datasheet.
&neodmium strong magnets.

For optimum coil calculations ,"coil maestro" software can be use.
0.3mm, 48 ohm, R=150mm coil inductance : ~50 mH.

Okay,
SPP-48 now you have a nice motor with the right coils.
Now you need to apply the electronics to switch the coils in the right
timing.
Have a look again at Mike?s last circuit diagram:
