My questions are concerning these kinds of motors: http://www.nidec.com/admtypem/admtypem.htm
Does it hurt these motors to be energized but not rotating? If so, what is the danger? Overheating the controller chip?
If that is the case, would adding a second or third .33ohm resistor in series with the resistor that's already on the controller board provide added protection? I realize that would reduce the torque output but that's okay.
