In the old days, they used to just put transformer laminations out into the yard and let them rust
I'm serious. The ferric (or is it ferrous
) oxide (technical name would be *rust*
) insulated the laminations. If you want to use '50's technology, then laquer them. I saw a post by someone (and I don't know who it was or I'd give them credit) who used just *one* of the laminations and a shot blast machine. He layed the lam on a piece of newspaper and *blew away* the un-needed paper. Put one of these pieces of newspaper between each lamination and you're set.
I guess a little epoxy or lacquer wouldn't hurt either
A p.s. to MR DIY: I suspect you made a start where you should have had an end on your motor - that's why it's a bit cock-eyed. You can argue all you want, but like Ron says, you want the phases symmetrical. Just my 2¢ on this.
p.p.s. - have enjoyed your input on the BLDC controller - you are talking WAY above my head on this stuff. I'm just slowly picking my way through a programming course on PLC's, and it's enough to boggle my *little* mind. The PIC's are too far ahead in the future for me to even see them over the horizon.....
