The DC motor. A small yet very powerful device that runs on Direct Current ranging from small voltage range of 3V to 9V. The device is very useful in the display and other rotatory motion machines. This plastic made body raises questions about its efficiency and efectiveness but in actual practice it can even turn a fan to rotate at a speed of about 100rpm, that would be enough to generate a lot of power.

The product finds its use in a number of appliations like Robotics. Display functions, Toys, Small Industrial machines, learning stuffs, DIY kits etc to name a few.
Never underestimate small things, as they can do big wonders.
