"WebA DC motor’s speed is proportional to the supplied voltage. If the voltage drops too far, the motor won’t get enough power to turn, but within a certain range, usually 50% of the rated voltage, the motor will run at varying speeds. The most effective way to adjust the speed is by using pulsewidth modulation. " - Dc motor checks
