Mostly Permanent Magnet Motor with minimal Input Power

[tinman]

Hi everyone,

I'm working on building a Super Tandem version of the Mostly Magnet Motor

Here is a video update of the building process

This is a very large setup you have got going here Luc.
Your going to need a lot of good sized magnets,and a truck load of wire lol. Would you think that .71mm wire would be a good size for this one?.

Hi Brad,

I already had all the magnet and wire supplies purchased over 4 years ago.  Just never built it because the topic didn't have that much interest and I was starting to doubt it would give the results I was looking for.
I still don't know but if I never build it, we'll never know.
So if I'm going to build it, I'll give it my best shot.

This design requires 8 of 2" x 2" x 1" thick N52 magnets for the center and 32 of 1" x 1" cube N52 magnets for the sides.

I used a coil calculator program to find the ideal wire size. Gyula recommended to keep the resistance to a minimum but to have the wire amp turns in the hundreds of turns.  Looks like16 AWG or 1.29mm wire gives (see attached) around 400 turns, so basically 200 turns each stand wound bifilar.
I also attached the result of 14 AWG wire (second shot) but the amp turns are not enough.
The inductance value is for air coil, so I'll only know its real value once it's sandwiched in between the cores.

I should have an update video in the next 24 hr. of the coil winding process and one coil already done.

Here is the video on winding the first coil and what it looks like when finished.

I checked the DC resistance of each bifilar stands and they are 1.3 Ohm each. The coil winding program had calculated 2.7 Ohms as a single coil, so we are right on track. I don't have my Inductance meter with me but will have it on Thursday.

Great craftsmanship!

Hey Luc

Its a Monsta!     Nice work, as always. 

Try a local hobby shop for your super glue/CA .    They have very thin (instant cure), medium and thick for filling larger holes and areas.  Its a lot cheaper than the normal store glues. A lot lot.    I use this stuff all the time.  I have 3  4oz bot of super thin, 2 8oz bot of thin and a couple of thick. No job is too big. lol

Also, try superglue with your fiberglass. Also carbon fiber strips from scrap cloth and superglue/CA can strengthen or repair many things. The CA is just like resin, its not real strong unless its with fiber, what ever it may be.

Also the CA at the hobby shops have fine tip applicator nozzles.
