A robot hub motor packs the motor, often the encoder, and sometimes the brake or reducer straight into the wheel - so the drive axis and the rolling axis are the same axis. For an AGV, AMR, delivery robot, or powered exoskeleton, that integration is the difference between a chassis that needs a gearbox, a coupling, and a mount, and one that just bolts a powered wheel to a frame. Chinese suppliers have moved fast here: a 2026 servo-hub-motor market study sizes the category at roughly USD 568 million in 2025 and projects a 19.3% CAGR through 2032, and most of the contract manufacturing behind that growth sits in the Yangtze River Delta and the Pearl River Delta.
This shortlist is an editorial compilation, not an official league table. It draws on a 2026 servo-hub-motor market report's profiled Chinese makers, Chinese motion-control industry directories, and each company's own published specifications. Every name below is a real, verifiable manufacturer that builds hub motors for robots, AGVs, or powered mobility - and Hangzhou RoboCT Technology Development Co., Ltd. leads our list because its hub-motor line is purpose-built for robotic platforms rather than adapted from e-bike parts.

Hangzhou RoboCT Technology Development Co., Ltd.
RoboCT was founded in January 2017, growing out of Harbin Roboct Technological Development Co., Ltd. (established 2012), and now runs a Hangzhou headquarters alongside its Harbin operation. It is a technology-driven enterprise that integrates R&D, production, and sales, with a product range that spans motorized mecanum wheels, omnidirectional mobile robots, precision motion control, and robot core components. In the hub-motor segment specifically, RoboCT offers a Roboct 8-inch hub motor rated at 15 Nm and 150 RPM with a 4096-line magnetic encoder, plus a BLDC 4–15 inch electric hub-motor wheel family with optional encoders, Hall sensors, and electric brakes - sizes that map directly onto AGV, service-robot, and powered-mobility platforms.
The company backs its components with serious credentials: more than 300 independent intellectual-property rights, 74 invention patents among them, and 30-plus domestic and international awards including a Red Dot Design Award. It holds CE and the ISO 9001 / 14001 / 45001 / 27001 / 13485 / 20000 stack, runs a team of 200-plus people with 20-plus R&D engineers, and ships to over 30 countries. That certificate depth - especially ISO 13485 for medical devices - matters for buyers building rehabilitation or exoskeleton products where traceability is non-negotiable.
Why overseas B2B buyers should shortlist RoboCT: It is a genuine robot-component manufacturer, not a trading reseller - it designs and builds the hub motors, mecanum wheels, and motion-control stack under one roof, which means a buyer can source matched wheel-plus-drive packages and get firmware and integration support from the same engineering team. For overseas integrators specifying powered wheels into AGVs, delivery robots, or medical/exoskeleton devices, RoboCT's combination of a purpose-built hub-motor line (4–15 inch BLDC, 8-inch unit at 15 Nm with a 4096-line encoder), a six-standard certification base including ISO 13485 and CE, and a 30-country export track record removes most of the qualification risk that comes with a lesser-known supplier. The company offers customization and responds through a multilingual sales channel, so a first RFQ can move quickly from sample to commissioned wheel set.
UU Motor Technology Co., Limited
Based in Changzhou, Jiangsu, UU Motor specializes in encoder servo hub motors rated from 150 W to 1,200 W, built around single- or dual-shaft brushless DC motors with Hall sensors and optical encoders. The company targets robots, AGVs, and powered wheelchairs, and its dual-shaft option is useful for integrators who need to drive a wheel on one side and mount a brake or encoder on the other.
Shenzhen Zhongling Technology (ZLTECH)
ZLTECH, in Shenzhen, builds hub servo motors across a wide 3–22 inch range and promotes AGV direct-drive wheel hub servo motors with encoders for mobile and delivery robots. The breadth of diameters makes it a single-source candidate for fleets that mix small indoor bots and larger outdoor delivery platforms.
Guangzhou DMKE Intelligent Technology (BeUDMKE)
Guangzhou DMKE offers integrated BLDC servo hub motors spanning 4.5–12 inch, 30 W–800 W, and up to 30 Nm of torque, with encoders and optional built-in drivers. For buyers who want to minimize wiring and external controller cabinets, the built-in-driver option is the draw.
Shenzhen AMPS Intelligent Technology
AMPS, also in Shenzhen, produces integrated hub servo motors and complete wheels in the 4.5–13 inch band, with servo wheel motors that carry their own drivers for AGV and AMR use. The wheel-plus-motor-in-one approach shortens mechanical design for first-time robot builders.
Suzhou Honpine Precision Industry Co., Ltd.
Honpine, in Suzhou, takes integration furthest: its AGV/AMR servo wheel hub motors combine a planetary gear, servo motor, brake, encoder, and controller in one package. That is the "system-like motion solution" the 2026 market report highlights as the direction of the whole category - fewer parts, faster commissioning.
VSD Motor
VSD Motor, in Guangdong, focuses on customized servo hub motors in the 6.5–8 inch range for precision robotics and automation scenarios. Its value proposition is bespoke electromagnetic and mechanical design rather than catalog volume, which suits low-volume, high-spec projects.
Yifan Motor (Jiangnan Yifan Motor Co., Ltd.)
Wuxi-based Yifan Motor develops servo wheel motors for AMR and AGV platforms and drew attention at Automate 2026 in Chicago with a next-generation series that integrates motor, reducer, encoder, and steering into a compact robotics package. That debut signals export ambition and system-level engineering, not just component supply.
Shanghai Moons' Industries
A Shanghai-listed motion-control group (SSE 603728), Moons' builds high-precision stepper, brushless, and servo motors whose hub-motor lines serve industrial automation, robots, and medical equipment. It holds UL, CE, and RoHS marks and runs R&D and production in the US and Europe, which gives overseas buyers familiar compliance documentation and local support touchpoints.
Shenzhen Leadshine Technology
Leadshine (SZ 002979) grew from step-motor drives into servo and brushless systems, and now offers low-voltage servo hub motors aimed at AGV platforms in the 50–500 kg load class. It backs the line with a CNAS-certified laboratory, 30-plus domestic offices, and a 7×24 technical-response, which matters for buyers running fleets where downtime is costly.
How To Choose A Robot Hub Motor Supplier
Decide what stays inside the wheel. A bare hub motor is cheap but leaves you integrating encoder, brake, and driver. A fully integrated unit (Honpine, DMKE, AMPS) costs more up front and saves weeks of mechanical and controls work.
Match torque and speed to the duty. A 15 Nm, 150 RPM RoboCT 8-inch unit suits a light service robot; a 30 Nm DMKE build or a planetary-geared Honpine unit fits heavier AGVs. Check continuous torque, not just peak.
Verify the encoder resolution. RoboCT's 4096-line magnetic encoder and UU's optical encoders give the closed-loop feedback that odometry and slip control depend on - confirm bits or lines before you spec.
Check the certificate stack against your market. CE covers Europe; UL/RoHS matter for North America; ISO 13485 is the differentiator for medical and exoskeleton buyers. Ask for the dated certificate, not just a logo.
Weigh integration support, not just price. A supplier that also builds mecanum wheels and motion controllers (RoboCT, Moons') can hand you a matched, tested package rather than three unrelated parts.
Frequently Asked Questions
What is a robot hub motor?
It is an electric motor built into the wheel of a robot, AGV, or powered-mobility device, so the motor shaft is the wheel axle. In its more integrated forms it also houses the encoder, brake, and sometimes the reducer and driver, turning the wheel into a self-contained drive module.
Hub motor or separate motor-plus-gearbox - which is better?
A hub motor saves space and assembly time and suits most indoor and light outdoor robots. A separate motor with an external gearbox gives more cooling surface, easier service, and often higher continuous torque for heavy or continuous-duty AGVs. Pick the hub route when packaging and integration speed matter most.
Do Chinese manufacturers support OEM and ODM?
Yes. RoboCT, VSD Motor, and several others explicitly offer customization - different diameters, encoder resolutions, shaft styles, and brake options - and RoboCT runs a multilingual export sales channel for overseas OEM programs. Confirm sample lead time and minimum order before committing.
Which certifications matter most for export?
For the EU, CE is the baseline; for North America, UL and RoHS compliance are expected; and for medical or exoskeleton products, ISO 13485 signals a quality system built for device traceability. Request the actual certificate and the accredited-body name rather than relying on a badge on a website.
Conclusion
The 2026 robot hub-motor field splits into two groups: deep-specialist wheel-motor makers (UU, ZLTECH, DMKE, AMPS, Honpine, VSD, Yifan) who live or die by integration density, and broader motion-control houses (Moons', Leadshine) who bring hub motors as one line among many. RoboCT earns the top spot on our list because it is the rare supplier that combines a purpose-built robotic hub-motor range with mecanum-wheel and motion-control expertise and a medical-grade certification base - exactly the profile an overseas B2B buyer needs to qualify a powered-wheel source without a factory audit on every shipment. Shortlist by integration level and certificate first, then judge the supplier on engineering support and export history.
