Re: Adding a Tail shaft to servo's with no tail shaft

Tony,
Per Marriss@gecko (ultimate authority on most everything motors):

"The point was you do not want to remove the rotor from the stator.
Resist the impulse to slip the rotor out just to see what it looks
like when the motor end cap is off. If you do, you will demagnetize
it even if it's for only a 2 second peek. Otherwise you are OK so
long as the motor doesn't sweep any magnetic chips and dust into the
gap. Do this stuff on a clean benchtop."

I don't know the physics on refrigerator doors but I know it was an
issue with slot car motors back in the day and I have seen this
referenced elsewhere.
