A Perendev is next on my 'things to do' list.
Judging by what i have read & seen, most of em are poorly designed, as i recall i posted both + and - comments on Brady's motor (the most well
known), However, Brady himself has not produced a real working model so far, only a pile of fancy parts & moaning about investors.
What does it cost? 100 Neo's are not that expensive.
I do think the theory is sound, check out Johnson's work.
I have also seen many basic design faults, such as;
1--Having equal numbers of magnets for both stator & rotor.
2--Using the right gap/unstable frame, smaller the gap greater the force.
3--Possible solution to (2) is to use a variable gap system(2 tracks not parallel) this is an extension of the linear motors, you will still have that
4--using 'keepers' to close the mag field (short them out) when not in use, otherwise the field leaks off into spacetime
Really, this is
important, a DC motor runs for years because the gap is so small, the field is 99% shorted when not running.
I will probably come up with some more common mistakes in a moment, but you get my drift.
It's mostly just common sense mixed with trial & error.
One thing is certain; The common mistake of ignoring the 'work' done by a magnet as it clings to your fridge (as in the work equation) is fatal, &
is taught in all schools. No scientist or univ. prof. knows how magnets work, they are fixed in a 4-D view of the universe, it's sad.....
Oh yes, S&F dude, i was going to post something on magmotors, never got round to it, thanks, you said it all for me
