Why does the reducer need a motor?

The reducer changes the speed through the engagement of gears of different sizes, which itself has the effect of slowing down the speed and increasing the output torque, so why should it work with a motor?I believe that many users also have questions about this issue.In order to answer our questions, the reducer manufacturer made the following introduction for us:

The purpose of matching the motor and the reducer is to increase the torque. When the load is large, it is not cost-effective to blindly increase the power of the servo motor. Therefore, the appropriate motor of the reducer will be selected within the required speed range.After the motor passes through the reducer, the speed of the output shaft will be reduced, and at the same time, its torque will increase, which meets the needs of the work.

The reducer can be linked in two ways, one is the way of holding tight, that is, the output shaft of the servo motor will extend into the reducer and link through the flange.There is a deformable hoop in the reducer. By operating the above locking screw, the hoop can hold the shaft of the servo motor tightly; the other is to connect by means of an external coupling. This connection method An external coupling is used, so a servo motor with a keyway is required.
