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.
