Keppe Motor simular to Newman-Bedini combination

[gmeast]

Hi Greg,

exactly a year ago I built a motor using 2 identical Microwave Oven Transformer Secondaries (removed from cores) stacked on top of each other with just enough space in between them for some 1/8" Bronze bushing for a shaft with 2 ceramic magnets 1 7/8" x 7/8" x 3/8" mounted on it. The magnets (in North South) have the shaft sandwiched between them in the center of the 7/8" dimension. The motor turned well and seemed to used Micro amps only.

Maybe I'll pull it off the shelve and make a new commutator for it and measure it with the better meters I have to see what it really does.

Anyways, great to see you looking into this, replicating and giving it your best as usual

Looking forward in your test results.

Hi Luc,

It sounds like you may have already built one of these.  The magnets you used are the same exact magnets I'm using on this replication:

McMaster - 5738K31 High-Temp Ceramic Rectangular Bar Magnet 1-7/8" Length, 7/8" Width, 3/8" Thick, 4 Pull lbs

Wow!  Thanks for your comments.  Take care,

Greg

Yes!... I forgot to mention that but the two magnets are Ferrite Ceramic. I just glued 2 spacers on each sides the shaft and of the same thickness as the shaft. I think I may of used Epoxy to keep the thing together. These magnets were a perfect fit for the MOT coils, next to no space wasted.

Maybe I should make a video of it!... Anyone interested?

Added: I just pulled it off the shelve and looked at the spacers I used between the magnets and they are strips of flexible magnets (like magnetic fridge add cards). I think that was a smart move on my part as it keeps the magnetic flux connected between the two magnets. I also did use Epoxy to keep the shaft in place.

Yeah man !

Why not attach a belt from the rotor of the keppe motor to a rotor of a generator to get some usable energy?  You could glue the bar magnets together as usual but then also glue some plastic fittings so the rotor is circular and a belt will fit.  The keppe motor could supposedly run itself and the generator at the same time right?

Yeah man !

Okay!  here you go
