Can a motor be run at any voltage?
A motor in itself can run at any voltage up to its rated voltage (and beyond provided a heat sink is added). The performance of the motor in terms of speed VS torque, and therefore the [speed;torque] operating point, will be decreased accordingly though.
How many volts to run a 12 volt motor?
The power adapter says 9 v output but there are 2 motors inside the decoration that shows 12 v. Does this mean the adapter is rated too small to operate the motors? The adaptor may be enough if the load on the motor (s) is not excessive. – Andy aka Jul 4 ’15 at 0:02
Is it Overkill to have a 12V motor?
Your 12V motors are overkill, but 12V motors are very common, so they must have been included in the design for their cost effectiveness and used under conditions that are less demanding than what they’ve been built for. Driving motors is not a very precise art (unless you want it to be!).
Can a 6V motor turn at 2V?
They can begin turning (With no load) way lower voltage than their “rated” or “designed” drive voltage. A 6V motor may begin turning at 2V for example. The issue is, as Andy Aka is hinting to in his comment, voltage relates to how much torque the motor can apply, which also ends up relating to velocity.

What happens when you put 5V on a motor?
Applying more than 5V will make the motor speed up. However, as it speeds up (unless it operates in vacuum) viscous friction will increase, requiring more and more torque.
