what's the point of doing that? I have been told by many people this method, to break the motor in, run it for 2 minutes at 2 volts. That's it that's all you need to do. And running the motor in until the serrations are gone?! They are there for a reason! When they are gone, you loose the benefit of the serrated brush and therefore whould be replaced once they are gone. When you break a motor in, all you are doing is seating the brushes to the comm.
