Gearmotor

 

an assembly composed of an electric motor and a reduction gear in a single unit. The most common types have planetary, planetary-lantern, and wave transmissions. For greater compactness, the driving gear of the reduction gear is mounted directly on the motor shaft. Gearmotors are used in universal drives for general use; they are manufactured serially by specialized enterprises. They can operate in a horizontal, vertical, or tilted position, depending on the lubrication system used.
