I've got everything put back together, but this BZ 6-8 motor is apparently shot. I took it apart yesterday and cleaned it up but there is a TON of grease and carbon on the windings. When I wired everything back up it spins but it is heavily bogged down and barely moves the machine.
Since they're so cheap, I'm just going to replace it with a new motor. And since I'll be sewing canvas, something with a little more power will be good anyway.
Any suggestions? I've seen a few videos on youtube where Vincent put a 1.2a Alphasew motor on. Everything looks pretty universal.
