What is a Planetary Gear Motor ( Knowledge Share)

A planetary gear motor is a type of gear motor that uses planetary gears to achieve a high reduction ratio. The planetary reduction structure is mainly composed of sun gear, planetary gear, and outer ring gear. Planetary gears are mounted on a stationary carrier. Then the shaft of the motor connect with the sun gear, It will transfor the power from motor to the gearbox. The planetary gears rotate around the stationary carrier and mesh with the sun gear to achieve speed reduction. At last, the power will output from the gearboxes’s shaft.
