Removing Windings "Best Way?"
 

Hi guys, Ive got a question I need answered. So we got our first batch of motors in yesterday and I was wondering how we could remove the windings without damaging the can. Im pretty sure that the windings are epoxied to the can wall and that would mean I would have to expose it to 200 degree heat to debond right? Or is it another type of adhesive?


Thanks in advance:yes:

Melting the epoxy is about the only way really, but that will damage the varnish on the windings too. If you can remove the front and rear endbells, then you might be able to punch out the windings, but you are more than likely going to damage them. Why'd you want to remove them anyway?

Their junk.

Hmm, well, what I did was kinda accidental- I had removed the rear endbell easily enough, and has trying to hammer out the front endbell, but somehow the vibtrations and sideways pressure on the windings caused them to start 'walking' out the rear end. I was using a long file and a hammer and tapping against the inside of the front endbell from the open rear end.

Not sure if that helps, but some kind of punch would work if you can remove both endbells, or try levering them out with a chisel. You may be better off talking to Lutach though, since he knows who OEMs alot of motors, so you may be able to source empty cans witha little luck...

Depending on what kind of motor and how the winding is actually held on the can it would be just as simple as using heat to melt what ever type of glue it's holding it there. That's what I did with a big motor I have just waiting to be rewound. Do you have any real experience in winding inrunner type motors? This is where things get tricky and any miscalculation will make a motor perform poorly.

Edit: Make sure you get a very cheap ESC to test the motor out incase you mess up on the winding. It's much cheaper then using some of the expensive machines the big guys use to check the motor.
