Dudley, Gear motor handbook, Springer, 1995, ISBN 9783540589884]])]) - 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 motor|asynchronous]], [[synchronous motor|synchronous]], [[DC motor|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.
