This would not likely affect any other parameter of the motor, the field winding would easily override the iron in powered operation.
If this IS the key, then there is no way to make a motor self-brake. You could mod it to bring out the field and armature wires separately, and rig a supply to the field and short the armature. That becomes a lot of work, though. Jon ------------------------------------------------------------------------------ Simplify data backup and recovery for your virtual environment with vRanger.
