I see,.. well, the design does have some glaring flaws for sure, the result of not knowing enough in the beginning,
and some purposely done to make the first build easy to make, and prove the point of the concept.
IE, make it spin. :thumb:
The experimental model sets the stage for the next gen's, which we assume will have a grate number of improvements.
It should have trapezoidal cores, and magnets,.. but it's very difficult to make laminated stacks like that, and getting
the right size trapezoid magnets is just as hard to do. I originally had envisioned ferrite cores for that propose, which
would have made it much easier, but it didn't pan out.
Trapezoids make for a much smoother motor, but also add a lot of weight. The question is, is it worth it for a DIY?
I expect it to run a bit rough, but I've seen other motors that are just as bad, and seem to run OK.
Let's find out.
The whole propose of this build is to show that a person can make his own motor at home. Improvements are inevitable.
To me, the ability to make vast improvements is 'the' exciting part. How many other motors can we do that to?
I didn't realize how much weight the cores would be, and should have made them as short as possible, but I don't know
how short that is yet. It's something that I can still go back and do though. (width of the motor)
As far as the wire size strands and wraps,.. I'll stick with what I have for the first test, as I don't wish to deviate too
far from a typical DD motor. I'll try to get get the coils tighter to the cores, but geeze,.. how bad can it be?
It's a bar magnet for crying out loud.
The magnets will be spinning past the stator plates which would seem to be a set up for induction, I agree, but induction
is only really a problem with close proximity,..thousand's of an inch. Once you get a few millimeters away, it is vastly
reduced. There will be about 3mm clearance here. Plus, it's rpm related as well, and 300 to 600 rpm is really slow.
