Stator resin not setting
« on: May 24, 2006, 02:48:29 AM »
I may be jumping the gun here, but . . . . .


I just cast my stator today, and I'm a bit concerned about the resin not curing.  I took a whole gallon of resin (wasn't sure how much was going to be needed, and I didn't want to come up short) and added aluminum trihydrate to it.  I was attempting to thicken it up a bit, but after adding nearly 3 quarts (by volume) it still was practibly runny as without.  So I stopped there and added the called for 1 ounce of MEKP to the mix, and mixed it up real good.  I did all my glassing and stuff, and sealed it up.  After 45 minutes, it still wasn't setting up, so I moved it on top of an industrial air conditioning unit that vents off a pretty warm blast of air hoping to coax it to set up.  I stuck around for another 15 minutes before heading home, and the overspill still wasn't really setting.


So what if I come back in the morning and it still hasn't set up?  Can a larger amount of heat save the day?  Hopefully, I'm just a little punchy, and all will be fine.  The epoxy for the rotors acted the same way, but was just fine the next morning.


Fingers and toes crossed.

as long as you added the correct amount of MEK , it should be fine .

was this stator using  your really nice triangular coils ?

details ?

Indeed they are the very same coils.  Three phase, nine coils, 14ga, two in hand, 71 turns, all starts and ends connected to terminals for any configuration.  


I'll do a write up of my progress soon, with pics, and some tricks that I didn't see anyone else doing.

If I ever figure out what's in the box then maybe I can think outside of it.

My first one took 2 hours to harden and my 2nd one took

18 hours to harden - same mix - so don't give up yet.

Well, I came in this morning to find that my pot of unused resin has set up, and did so without signs of cracking.  I'm looking forward to popping open the mold at lunchtime and see how I did. (I'm doing my construction at work)  I'm feeling a bit better now.  ;-)
