compact gear motor miniature planetary gearbox

---

Common planetary gearbox base sizes include 42, 60, 80, 90, 115, 120, 142, 160, 180, 220, 240, 280, 

330, 350, 380, 400, and 440.

Miniature planetary gearbox base sizes are commonly 22, 28, 36, 42, 60, 70, and 90 mm, 

suitable for miniature DC, stepper, and servo motors. 

These are low-backlash precision miniature gearboxes used in medical devices 

and small-scale automation applications.

Miniature planetary gearbox bases are mainly classified by flange 

outer diameter: ultra-miniature 22/28/36 mm, and precision 

standard 42/60/70/90 mm. All models are compatible with miniature 

DC, stepper, and low-power servo motors.

Integrated aluminum alloy body, backlash within 3 arc minutes,

 IP65 seal, selectable reduction ratios from 3–100, 

customizable mounting flange and output shaft diameter, suitable for small robots, 

testing instruments, and smart devices in confined spaces.

Compact gear motor paired with a miniature planetary reducer: small size, 

high torque density, and high transmission efficiency, 

suitable for medical devices, small robots, and smart devices in confined installation environments, 

supporting customized voltage and reduction ratios.

For space-constrained equipment, the compact gear motor and miniature planetary 

reducer are the preferred choice. 

The coaxial planetary structure significantly reduces the overall size, 

and multiple teeth share the load to achieve high torque output in a small volume. 

Precision-ground gears allow for controllable backlash, achieving a transmission efficiency 

of up to 97%, and low-noise, stable operation.

Lightweight aluminum alloy body, IP54/IP65 seal options, full voltage coverage for DC 12V/24V and AC, 

multiple reduction ratios, and customizable flange and shaft diameter. Widely used in mechanical grippers, 

testing instruments, smart homes, and micro-automated production lines, supporting OEM customization.
