The issue is though, that you assumed it was rated at 3v, but I didn't know what it's maximum voltage rating capacity was, I only knew it was powered by 2 AA batteries.
If you re-read my post you will see that I didn't make any assumption about what the motor's rated voltage was. I described how much effect the change from 3V to 9V would have on the current and heat and then said that if you exceed the rated voltage by a factor of three this would be very likely to damage the motor. You haven't said what the rated voltage is, so I have no idea whether you're exceeding it or by how much.
