Inside a Feigao (type) motor...

Very odd. Try using a long (and thick) flat bladed screwdriver, insert it into the motor, and then lever it under the end of the windings- there should be a small gap between the winding sand the front endbell of the motor internally. You could also try the wooden dowel/ broom handle method like mentioned- hammer it against the windings to break the glue bond, then it should be easy to just slide the windings out with a hook of some kind.
