I have a small UPPCO electric motor that used to drive the
circulating fan in a household convection oven. It seemed to be
dragging a bit, so I took the oven apart to lube the motor. It worked
OK before I disassembled the motor. When I put it back together, it
would no longer work.
The rotor spins freely so long as there is no power. When power is
on, the magnet prevents the rotor from turning at all. The motor only
has 4 parts, and there really is no choice about how it goes together.
So, how the heck did I mess it up, and how can I fix it?
