They are motors that are run with batteries. Like in your toys. 1st grader should figure that one out.

DC stands for Direct Current (not AC or Alternating current like house current)
DC current comes from batteries.
The motor had two wires that connect to DC electricity - when the electricity goes into the motor it causes magnets to become magnetized and repel or attract other magnets in the motor. The repelling and attracting causes a shaft to turn that sticks out of the side of the motor! The shaft is used to do work like spin a fan or propeller or turn a wheel, a CD or DVD disk or they can even make a car move by moving gears in a transmission.
AC motors perform the same work but use Alternating electricity instead of DC.

A dc motor is a direct current motor. They have lots of uses. Anything from power your video recorder head in a vcr to radio control toy cars. A dc motor supplies rotative motion to battery operated devices. Your portable fan that you can purchase out of a general dollar store uses a dc motor.

Motor powered by dc voltage.
Motors are sources of power.
An example of a device with a dc motor might be a battery operated drill or vibrator...lol...
