Hopefully somebody on FL has tinkered with one, and can give you some tips.
A lot of folks here can talk to you (at great length, I might add) about the principles, materials, and techniques you'll need to do that, if it's feasible. But most of it would all be generalized, because I assume many of us haven't seen a LG motor in person. I have seen some of the "smart-drive" washer motors taken apart, but I didn't know if they were LG motors or some other OEM's. Also, LG might make many different types, sizes, configurations of motors to suit a wide variety of washing machines. So one person's LG motor project might not look like yours...
If you're willing to show a few pictures, maybe illuminate the rest of us about what the differences are between a LG and a F&P, then we'd have a start at something more specific to help you with.
