Why Does The Electric Motor Should Use Speed Reducer (Gearbox)?

The main purpose of the gear reducer is to change the output speed of the motor relative to its torque.

So, what are the benefits of the speed reducer (gearbox) in using?
The speed reducer (gear box) can effectively protect the motor. In operation, the torque that the reducer bears is greater than that of the motor, and when it is overloaded, it is transmitted to the motor as long as the overload is divided by the gear ratio.
Save cost. If it is assumed that the motor directly bears the torque, the motor will be damaged when overloaded. On the contrary, if there is a reducer in front of the motor, simply replace the reducer and the cost is lower.
The reducer effectively reduces the moment of inertia and can control the start and stop and speed changes in time. On the other hand, increase the torque through the reducer instead of increasing the input power. Therefore, for the cost of increasing power, the reducer is cheaper than the electric motor.
Effective energy saving. The use of a speed reducer can meet the same output torque with less current.
The speed reducer can effectively reduce the speed and increase the torque, according to the motor output gear ratio.
Effectively reduce the load inertia of the motor.
