Typical Applications for 3V to 6V Brushed DC Motor:

• Motors are fantastic instruments with a far-reaching range of applications; hobbyists will find this little brushed DC motor especially useful. This motor can be readily utilized with 3.3V and 5V Arduino Boards and other Dev Platforms because it has a pretty wide voltage range of 3V to 6V DC. You won't have to worry about stepping the voltage up or down to match the motor.
• Because of this, you can move this motor around from project to project as needed. You can even build a snap-fit connector to enable you to "unplug" the motor from one item, like a small fan, and plug it straight into another, like a homemade magnetic coffee stirrer, without worrying about complicated connections. As an alternative, you could just buy a new motor for every purpose you need it for—you could even use two motors at once using gearing if the project calls for more power—especially because these motors are quite reasonably priced and accessible to hobbyists.
