Characterized by small volume, high transmission efficiency, extensive reduction range and high accuracy, a planetary gear motor is a piece of drive equipment extensively used in robots. The structure of the planetary gear motor makes the minimum single-stage deceleration reach 1, The stage of planetary gear motor is usually ≤ 5. Compared with other gear motors, planetary gear motors have the characteristics of high rigidity, high accuracy, high transmission efficiency, high torque/volume ratio, and long-term maintenance.

A planetary gear motor for the robot is one of the essential core components that fulfills high requirements for positioning accuracy and repetitive positioning precision. It is different from other conventional planetary gear motors, as they should be small in volume and adequately lightweight for robots to perform repetitive acts during operation. Planetary gear reducer for intelligent robotic operation, RV reducer, and harmonic reducer for robot joint are broadly used in the robotics field. As the name implies, planets revolve around stars. The planetary gearbox has three planet wheels revolving around a sun wheel. The robot planetary gear motor is compact, lightweight, high carrying capacity, long service life, stable operation, and low noise. Characterized by power splitting and multi-tooth meshing, a planetary gear motor can be used alone for intelligent robots.
