A planetary gearbox is a gearbox with the same center of rotation for both input and output. This means that the center of the input gear rotates around the center of the output gear, and the input shaft and output shaft are aligned. The structure of the planetary gearbox reduces the transmission speed ratio while increasing the motor torque proportionally.

Planetary gearboxes are used in various occasions where efficiency and high reduction ratios are needed in a small space. With high precision and high torque volume ratio, they are very suitable for the following applications: increasing torque, reducing speed, accurately positioning and controlling reproducible machinery. In order to ensure that the selected planetary gearbox is most suitable for your application at hand, it is important to consider specifications including torque, backlash and ratio when selecting a planetary gearbox.

PLE23-G5-D10 is a high-precision planetary gearbox, it is belong to PLE series gearbox, it with gear ratio 5:1 and a maximum 15 arc-min backlash. It's an excellent choice for applications that require good accuracy and reliability at an exceptional value. This inline planetary gearbox built-in an input shaft coupling which can match any standard 10mm diameter shaft of Nema 23 stepper motor, brushless dc motor and servo motor.
