Custom Robot & AGV Hub Motor Wheels with Premium PU Coated

The AstraRoll Technical Advantage: Mastery of Polyurethane & Customization
Standard rubber tires degrade quickly, and generic hub motors often fail to integrate cleanly into custom robot frames. We engineered our manufacturing process to give robotics developers total control:

The Premium PU Coating Edge: A powerful motor is useless if the wheel slips. We cast our wheel exteriors with proprietary, high-friction Polyurethane. This formulation provides aggressive traction on dusty or slick warehouse floors, ensuring your robot's odometry and navigation algorithms remain highly accurate. Furthermore, the PU layer acts as a vital shock absorber, protecting the sensitive internal motor magnets and encoders from facility vibrations.

Zero Delamination Guarantee: The biggest failure point in coated motor wheels is the PU peeling away from the metal hub under high torque (delamination). AstraRoll utilizes advanced chemical bonding and mechanical interlocking techniques during the casting process, ensuring the PU tread and the motor hub act as one indestructible solid piece, even during heavy payload cornering.

True "Built-to-Order" Powertrains: Tell us your robot’s target payload, top speed, and battery architecture. Our electrical engineers will custom-wind the motor stators and select the perfect gear reductions to deliver the exact torque curve your application requires.

Space-Saving Chassis Integration: By putting the motor, brake, and sensors directly inside the wheel rim, we drastically reduce the footprint of your drive unit. We further support this by offering custom-machined mounting shafts and brackets, allowing you to free up critical space inside your chassis for larger batteries or computing units.

Frequently Asked Questions (FAQs)

Q: Delamination (the PU peeling off the metal hub) is a huge problem with our current motors. How does AstraRoll prevent this?
A: This is the #1 reason engineers switch to AstraRoll. Delamination happens when cheap adhesives fail under high torque. We don't just glue our PU to the motor housing. We use a combination of advanced chemical bonding agents and mechanical interlocking (machined grooves on the motor casing) during the hot-casting process. This ensures the Polyurethane and the metal hub act as a single, indestructible unit, even during heavy payload pivot turns.

Q: Do I have to buy your motor controllers, or can I use my own?
A: Our BLDC hub motors and encoders use standard industrial wiring protocols, meaning they are compatible with the vast majority of high-end third-party motor drivers (like Curtis, Roboteq, or Kelly). However, if you want a true plug-and-play solution, we can supply matched and pre-calibrated motor controllers along with the wheels.

Q: What is the Minimum Order Quantity (MOQ) for a custom-wound hub motor?
A: We understand that robotics development requires testing. For custom prototyping, we offer very low MOQs (often just 2 to 4 units for an initial chassis build). Once your prototype passes your internal testing, we scale up to full OEM mass production to support your fleet rollout.

Q: Should I choose a Direct Drive motor or a Planetary Geared motor for my robot?
A: It depends entirely on your payload and speed requirements. If your robot is lightweight (e.g., a 50kg hospital delivery bot) and needs to be fast and whisper-quiet, Direct Drive is perfect. If your AGV needs to pull a 1,000kg pallet from a dead stop, you need torque over speed—in this case, our integrated Planetary Geared hub motor is required to multiply the pulling force.

Q1. Are you a trader or direct factory?

We are a direct manufacturing factory with over 20 years of expertise in high-end industrial rollers, casters and material handling solutions. Our facility operates with ISO-certified quality management systems, allowing us to maintain full control over production cycles and quality standards. Throughout two decades of growth, we have established deep, long-term strategic partnerships with several listed companies and global automation leaders, proving our reliability as a high-tier industrial supplier.

Q2. What are your main products?

AstraRoll specializes in the engineering and production of three core product lines: Industrial Rollers, Heavy-Duty Wheels, and Precision Casters. We do not just sell components; we provide integrated movement and transport solutions. Our products are widely utilized across high-demand sectors, including: New Energy, Lithium Battery, Mining, Heavy Industry, Medical Institutional, Agriculture and Logistics.

Q3. What about delivery time?

We deeply understand that project timelines are critical.
Standard Products: Usually dispatched within 7–15 working days if the components are in stock.
Customized/OEM Orders: Depending on the complexity and volume, the lead time typically ranges from 20–35 days. This includes time for technical drawing confirmation, specialized tooling, and rigorous pre-shipment testing.
Shipping Methods: We offer flexible global logistics solutions, including FOB and CIF terms. We ship via Sea Freight (for bulk industrial orders), Air Freight (for urgent project needs), and International Express (DHL/FedEx/TNT) for smaller components or samples.
