The Difference Between a Gear Reducer and a Geared Motor

A gear reducer is a mechanical device that reduces the speed of a motor while 

increasing torque and matching 

inertia through gear meshing. It is a purely mechanical device and can be classified according 

to transmission 

type as gear reducers, worm gear reducers, planetary gear reducers, cycloidal pinwheel reducers, 

RV cycloidal reducers, and harmonic reducers.

A geared motor, on the other hand, combines a gear reducer and a motor to 

form a mechatronic device. 

It is the most common device in industrial applications and plays an important role 

in the automation industry. 

It can also be used in conjunction with frequency converters, controllers, and displays 

to achieve a wider range of applications.

Common gear reducers can be used with ordinary three-phase AC motors, 

explosion-proof motors, frequency converter motors, 

brake motors, servo motors, brushless DC motors, stepper motors, 

permanent magnet synchronous motors, etc., 

to achieve various automation functions. They play an important role in industry.

In short, the core difference between a gear reducer and a geared motor is that 

one is a purely mechanical speed reduction device, 

while the other is a mechatronic device that combines a gear reducer and a motor.
