Depends upon the design of the motor, but at a guess you'll get more from the 12V one. L

about the 12v motor, can i get much torque and rpm if i connect it on a power source larger than 12v? for example i connect it in a 16v?thanks...

16V would give you more, but it would be prone to overheating. Short runs OK, long running it would probably fail. L
