can anybody give me a discription of a planetary gear motor and how it differs from other motors ?

A planetary gear motor can give greater torque and less backlash in a more compact size.
They get in your pocket for this feat, however...

planetary gears are composed of three parts:
Sun: The central gear
Planet carrier: Holds one or more peripheral planet gears, of the same size, meshed with the sun gear
Annulus: An outer ring with inward-facing teeth that mesh with the planet gear or gears
In many planetary gearing systems, one of these three basic components is held stationary; one of the two remaining components is an input, here you connect your motor, providing power to the system, while the last component is an output, receiving power from the system. The ratio of input rotation to output rotation is dependent upon the number of teeth in each gear, and upon which component is held stationary.
