Well, I think that having a working motor, the only way you're going to get any acceptance is if you have a big name sitting there next to you doing the actual announcement.  Bill Gates or Steve Jobs?  Maybe not, though Bill Gates did just come out stating that we need to get away from the carbon (coal, natural gas, petroleum, etc...) economy and move towards a solar/wind/renewable economy, so he might not be in the "no hope in hell" category, provided you have a working design.

That being said, we can get back to more relevant discussion - design and testing.

I have been doing some small tests and have noticed that it takes a LOT of power to repel 2 magnets that are in attraction.  This might be because I'm using 2 thicker magnets (you're using thin magnets, right?), so their field extends quite a bit, compared to a pair of thinner magnets.  I've got a few thoughts on what to do about this.  I'll let you know more tomorrow evening about my tests with that.

After a small amount of testing, repelling a magnet with metal on the other side (think of your 2-piston motor with 1 magnet and 1 piece of metal) and, while the pull force is around half (actually around 45%), the repel wattage is less than a tenth.

2 magnets in attraction:

56.7 volts @ 14 ohms = 4 amps, 230 watts - not enough.

1 magnet with steel:

9.15 volts @ 14 ohms = .65 amps, 6 watts - not enough
18.3 volts @ 14 ohms = 1.3 amps, 24 watts - more than enough

I'm going to have to look this over and do some thinking.  I might test with 12 volts to see how that works (12v @ 14 ohms = .85 amps, 10.3 watts).

I need to wind some more electromagnets, both thicker and wider (.9" wide, .25" thick) to see how much of a difference that makes.

It is very important to match the coil to the magnets. Spend time on this aspect of the motor. 2 magnets on each side of a coil act differently than one especially when they are in motion.

Much more powerful than I had expected.  Are you still using an iron/steel core EM or are you using an air core?

As I said, "It is very important to match the coil to the magnets". I have used both iron and air core.

Are you currently using air or iron core though?  Due to the peculiarities of PM on iron core EMs, I think that it would work better with an air core, but I'm curious what your experience has been.

As for matching coils to the magnets, I'm not sure exactly how you mean that - build an EM that produces the same force as the PM has or... ?

Since you and I are the only contributers to this thread taking up space from the more popular Ozzie thread, perhaps you should send a personal message to me.
