Tips for Powering Motors with Batteries
For example, while a 3V motor will likely run from a 1.5V AA battery but you will get better performance connecting two AA batteries in series to create a 3V supply. Conversely, if the motor is rated at 1.5V using a 3V battery runs the risk of immediate damage to the motor (as would anything above the Maximum Operating Voltage).
