Reducer, what do you use it and what is the difference between ordinary motor?

Reducer is a kind of dynamic convey institutions, using the gear speed converter, put the number of rotary motor slowdown to turnover number, and get a larger torque. Slow down at the same time improve the output torque, torque output ratio according to the motor output by reduction ratio, but not beyond the reducer rated torque. Speed and reduce the load moment of inertia, moment of inertia of the decrease of reduction ratio of the square. You can have a look at general motors has a inertia value. General reducer with oblique gear speed reducer (including parallel shaft helical gear reducer, worm gear reducer, bevel gear reducer, etc.), planetary gear reducer, cycloid pin wheel reducer, the worm gear and worm reducer, planetary friction type mechanical CVT machine, and so on.
