This general subject has been discussed here before. I'm sure you can search
the lugnet archives for more info.
However, as my supply of motors has aged, I too have noted that they do tend
to seize or at least stiffen up with lack of use.
I have rejuvinated a few in that state by momentarily applying 9 - 10 volts
from a fairly stiff source like a lab power supply. If you apply power in
the forward and then reverse direction a few times, you may well find you
can "jerk" the motor back to life.
The really bad thing to do is to atemppt to force it by turning the shaft.
The internal gearing up is so extreme, that in all likelyhood, you will
irrepairably damage something. It is much better to try and free the gear
train from within!
