1, reduce speed, speed reducer, just as its name implies, the preferred function is slow, it is mainly aimed at the object of deceleration motor, servo motor and stepper motor, is the same effect, because in many practical occasions of the motor, it is difficult for us to completely to use motor rated speed, because it involves a lot of other functional requirements and the principle of matching, So we will slow down the speed of the motor, and it is a very common practice to slow down through the reducer.
2, increase torque, speed reducer is indeed a very wonderful things, at the same time of deceleration, he also can increase the corresponding motor output torque, this feature for equipment research and development personnel, really is too perfect, it's like you go to the jingdong shopping, businesses not only at a discount, also send you a package, isn't it the best of both worlds, Speed reducer is such a good thing.
Archimedes once said: Give me a fulcrum and I can move the earth. You can also say: Give me a speed reducer and I can turn the world with one finger.
3, reduce the inertia motion mechanism, do people know that the research and development of mechanical structure, equipment, the movement of inertia "is a very annoying thing, if a bad motion inertia matching, movement of stability, accuracy, and life will be affected by a very large, but we can't go to inertia matching unlimited increase the choice of motor, So that's where the speed reducer comes in.
