You can not power a 5V motor with a 12V supply, unless you keep it submerged in liquid nitrogen to deal with the heat. You can not power a 5V motor directly off an Arduino, motors draw too much.Click to see full answer. Keeping this in consideration, can I run a 12v fan on 5v?Most fans will not start up at 5v but many will run at 5v. The start up voltage is how much voltage the fan needs to overcome interia and begin to move the fan blades. Once the blades get up to speed, the fan can run on much less voltage.Similarly, will a 12v motor run on 9v? No. You are applying too much voltage to the motor. This will cause too much current to flow, and in turn, burn out the motor. Others have suggested putting the two 9V batteries in parrelel, but that is not good either, as the 12V moter will get an under-voltage, and not run properly either. Correspondingly, can a 12 volt motor run on 6 volts? Same as with the motor, if you provide 6 V to 12 V motor, your motor will run on half of its rated speed and the torque will also reduce. So, if you want to avoid the heating of motor, you have to cut down the load by 50%. But the motor still runs on half of its speed.How do you find the voltage of a DC motor?Start by measuring the DC resistance of the winding. This will give you an idea of the current draw (Stall current) at different voltages. You can guess at the possible power rating (input power in Watts) by comparing size to other motors then calculate what voltage would give this power input.
