Those magnets are very tempting, and I'm still struggling with the idea. My budget is getting taxed from the current motor
project at the moment,.. plus we need the results from this build to make sure that things are viable.
But the little gears in my head are spinning, to be sure! It's not 'that' much $$. Hmmm...
A beefy motor with those magnets would probably need a re-inforced carrier, bigger cores, thicker back iron, and
thicker wire, plus a big battery and controller. Would be fun though, for sure. Might push the limit of bike parts
as a mid drive.
To add to the temptation,.. I have the Muscle Cruiser bike thats slated for a build in the near future, that would be a
good candidate for a big motor. And I came into a windfall of used lithium packs last summer, so I have batteries.
I know,.. not everybody likes cruisers, but I'm into them.
Off road bike would be cool too, but I like asphalt.
Dui, ni shuo de dui, cutting in water is a good idea, and should take care of the heat, and dust, as you said. That would be
a good advancement in this tech for sure. The magnets aren't actually cut with the Dremel, just scored, but scoring them in
water would work better, if I can figure out a logistical way to do it, with water, and have good visibility.
I'm thinking I'll need to make a small machine of some sort for the task.
