Sweg Motor
Engineered for High Torque, Low Noise, and Unmatched Durability.
As a leading planetary gear motor manufacturer, we understand the shift toward high torque density and smart integration.
In the modern industrial landscape, planetary gear motors have become the backbone of precision motion control. Unlike traditional spur gears, the planetary arrangement allows for load sharing across multiple gears, which significantly increases torque capacity and shock resistance while maintaining a compact footprint. Our expertise as exporters centers on providing Information Gain—not just selling a motor, but optimizing the entire drivetrain for efficiency.
Demand is surging for 8mm to 16mm micro planetary motors for medical surgical tools and wearable tech, where every millimeter counts.
Global carbon neutrality goals are driving the adoption of high-efficiency brushless DC (BLDC) planetary units to maximize battery life in mobile robotics.
Future-ready motors now include integrated magnetic encoders and CAN bus communication for real-time diagnostics and predictive maintenance.

Zhejiang Sweg Motor Co., Ltd. is a premier professional manufacturer specializing in the research, development, and mass production of electric motors and high-precision gear solutions. With a sprawling 10,000 square meter facility, we leverage automated stamping, CNC winding, and intelligent assembly lines to deliver millions of units annually.
Custom-tailored transmission systems for high-stakes industries.
From electric bicycle drive systems to seat adjustment motors, our brushless DC planetary reducers provide the high torque and reliability required for the automotive sector. Compliance with IATF 16949 standards is at the core of our export philosophy.
Low-noise, low-vibration motors are essential for infusion pumps and surgical robots. Our 10mm-16mm series offers the ultra-smooth operation necessary for delicate medical applications.
In the era of Cobots (Collaborative Robots), planetary gearboxes offer the high reduction ratios needed for precise joint steering. Our 42mm high-torque series is specifically designed for multi-axis robotic joints.
Driving the next decade of motion control innovation.
Everything you need to know about specifying the right motor for your project.
Planetary gear motors offer higher torque density because the load is shared among several planet gears. This design provides better stability, higher efficiency (up to 95%), and a much longer service life compared to spur gears, especially in high-torque applications.
Yes. As a custom planetary gear motor manufacturer, we can adjust the number of gear stages (1-stage, 2-stage, 3-stage, etc.) to achieve precise ratios ranging from 3:1 to over 2000:1, ensuring the output speed meets your application's exact needs.
We use high-precision CNC gear hobbing and specialized lubricants to keep noise levels below 45-50dB for standard models, with ultra-quiet options available for medical and smart home devices.
Our production follows ISO 9001 standards. Every shipment can be provided with CE, RoHS, and REACH documentation. We also support UL and CSA certifications for the North American market upon request.
Prototype samples are usually ready in 7-10 days, while mass production for standardized models takes 3-4 weeks. Fully customized solutions may vary depending on tool development requirements.
Ready-to-ship and customizable models for every torque requirement.
