Reducer is through different sizes of gear bite to change the speed, itself has the role of slowing down and improve the output torque, then why should also work with a motor? I believe that many users also have questions about this issue. In order to answer our questions, reducer manufacturers have made the following introduction for us:
The motor is paired with a reducer in order to increase the torque, when the load is very large, it is not cost-effective to increase the power of the servo motor, so it will be in the range of the required speed to choose the appropriate motor for the reducer. And the motor through the speed reducer, will reduce the output shaft speed, while its torque will increase, to meet the needs of the work.
The speed reducer can be linked in two ways, one is the way of holding tight, that is, the output shaft of the servo motor will be extended into the speed reducer inside, and linked through the flange. There is a deformable hoop inside the speed reducer, and by operating the locking screw on it, the hoop can be made to hold the servo motor's shaft tightly; the other is to connect it by means of an external coupling, and this connection adopts an external coupling, so it needs a servo motor with a keyway.
