Hello cobree,
I have a few wire combo's to try. The 1st stators will be wound with 14 AWG magnet wire. I am going to try to match the copper density of a large outrunner on the 1st few attempts. hopefully all will work out.
I got a little busy in the afternoon with family stuff but made time to fire up the foundry & cast a couple magnet rotor blanks for the mule.
Why cast? properly designed castings are incredibly light & can be wonderfly strong. All without spending hours tediusly turning the handles on a mill or lathe. It is also far more cost effective than cncing parts from an expensive oversized billet. As a woodworker, I can make just about anything & reproduce it in metal.
here is tonights fun pictorial.
This is my home built super efficeint furnace, I am fireing with propane. looks totaly ghetto as a recycled paint can
I have poured cast iron from this set up.
A crucible full of old geo metro head. the high infra red radiant messes with the camera its not quite that bright
There is the pattern & behind is a mold all ramed up with gates & risers in place
poured & cooling off. I poured these at 1280f.
To the band saw to cut off the risers
I did a little clean up on the lathe & got the all important hole in what will become the center of the part.
you can see another one in the background. It is important to allways have an extra cast. Once you have 2 of something, all your set ups will be perfect & you won't need the spare
if you only cast one, it is garenteed you will brake a drill bit off in it somewhere along the line. I still need to cut the depth for iron flux ring & magnets, then machine off a little weight. I was a bit conservitive on the pattern to make molding it easy & avoid any shrink issues. Then it will get polished like a new dime.
(ignore all that sprocket clutter on the bench in the back ground. that is for a project to be unveiled soon :wink: )
