Gearmotor1) (also gear-motor2) or gear motor3)) - a single compact device which comprises both: an electric motor and a set of gears, usually for reducing the rotational speed and increasing torque of the output shaft.

Depending on application, almost all types of motors can be employed in gearmotors: asynchronous, synchronous, direct current, etc.

Similarly, the reduction gears can be of many types: worm, cogwheel, planetary, planetary-lantern, and wave transmissions. Type of gears and lubrication system might limit the position in which the assembly can operate.
