The role and type of planetary gear motor:

The reducer generally achieves the purpose of deceleration by engaging the motor, internal combustion engine or other high-speed power through the gear with a small number of teeth on the input shaft of the reducer to mesh with the large gear on the output shaft. Torque transmission equipment, this is a common sense problem, so I won't talk about it more. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal deceleration effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.


1. Reduce the speed and increase the output torque at the same time. The torque output ratio is the motor output multiplied by the reduction ratio, but it must be noted that the rated torque of the reducer cannot be exceeded.

2. Speed ​​reduction reduces the inertia of the load at the same time, and the reduction in inertia is the square of the reduction ratio.You can see that a general motor has an inertia value.


The general reducer includes helical gear reducer, precision planetary reducer, servo dedicated planetary reducer, right-angle planetary reducer, planetary gear reducer, helical gearGear reducer, Powerful reducer, precision reducer, cycloid reducer, worm gear reducer, planetary friction type mechanical stepless speed changer and so on.
