Structure
The structure of planetary gearbox with motor generally follows a specific arrangement to achieve its functionality
Motor
- Core component that provides the rotational power.
- brushless motor or brushed motor.
Sun Gear
- Center of gearbox, driven by input shaft.
- Transfers motion to the planet gears.
Planet Gears
- Planet gears meshing with sun and ring.
- Carrier-mounted ensures even load distribution & high torque.
Planet Carrier
- Secures planet gears, enabling free rotation.
- Transfers combined torque to output shaft.
Ring Gear
- Large gear encircles and engages planet gears.
- Fixed or rotating, adjusts gear ratio.
Output Shaft
- Connected to the planet carrier.
- Delivers the output power to the driven equipment.
By Commutation Type
We can custom and manufacture brushed and BLDC planetary gear motors for you, making your project more cost-effective.
Brushless
- BLDC planetary gear motor features electronic commutation with magnets, eliminating brushes for reduced wear.
- With a diameter of 20mm-28mm, it operates at a rated speed of 5rpm-2000rpm and delivers torque between 500mNm and 4000mNm.
- It offers longer lifespan, low maintenance, and enhanced speed and torque control.
Brushed
- Brushed planetary gear motor features mechanical commutation with brushes that wear out over time.
- It has a diameter range of 6mm to 42mm, a rated speed of 4rpm to 12,000rpm, and torque between 1mNm and 160,000mNm.
- It provides simpler control but has a shorter lifespan, needing regular brush replacement.

- Efficiency above 95%.
- Suitable for low-to-medium torque needs, such as electric tools, actuators, or compact robotics.
Two-stage Planetary Gear Motor
- Two gear sets in sequence.
- Moderate torque and medium reduction ratios (10:1 to 100:1).
- Efficiency is 90% to 94%.
- Used in moderate-load applications like conveyors, medical equipment, and precision drives.
Multi-stage Planetary Gear Motor
- Three or more stages.
- High torque and large reduction ratios (over 1000:1).
- Efficiency is 80% to 90%.
- Best for high-torque, low-speed tasks such as industrial automation, robotics arms, and packaging machines.
By Material
We use MIM technology to customize the material of the planetary gearbox,including plastic and metal.

Customer Case
Planetary Gear Motor for Vacuum Cleaner Brush
A home appliance company approached us seeking a cost-effective motor solution for their vacuum cleaner’s roller brush.
Understanding that the roller brush typically has a limited service life—often under 200 hours—we developed a 12V brushed DC motor with a 30:1 planetary gearbox, delivering 0.8 Nm torque. By selecting a brushed motor instead of a brushless alternative, we helped reduce the customer’s cost by approximately 40%, making it more suitable for disposable or replaceable components in household vacuum systems.
This solution successfully balanced performance with cost-efficiency, aligning perfectly with the client’s product life cycle strategy.
