500KW generator - Barrel coils removal

So they are NOT epoxied - there's just a plastic slug that acts as a lock. But that's where the good news ends.

I tried cutting the ends off like a regular stator, but I'd need a 6" disc to get to the rearmost windings. Has some luck peeling the top winding out by choosing the first few wires to tug on, but that would have taken forever...then it would have block off the rear winding. The sawsall is NOT cutting through the end of the winding, even with a Torch blade.



So hardware stores are still close today, and I can't refill my Oxy-Acet tanks today - I think gouging out the laminated core would probably have been the fastest course.

I'll get back at her this morning, hoping to think of a new angle to try after a nice pot of coffee.

I believe you mentioned a gantry crane in your video. Once one end of the windings are cut, can you hang it from the other end and only grab a couple of windings at at time. Pick it up off the floor a few inches and see if gravity will do its work. May take a little bit of time.

Diamond blade for the grinder would be a good idea.

I tried letting one of the winding hang, the stator is around 1500 lbs, but nothing. Tried going down to a few strands, and they just broke. What doozie! I even tried a bottle jack inside of the housing on one of the winding - it pulled them a little bit, but ended up snapping the wires.

I've got about a third of it done right now, seems I found a comfortable setup where I can peel the wires away with a small and large pry bar. I'm hoping once the outer ring is done, it'll have loosened everything enough that I can try hanging and use gravity's help while prying or hammering.
