Electric Geared Hub Motor

Split-type electric geared hub motors are electric motors integrated within the wheel hub, typically employed in robotic chassis. Featuring a modular design, they accommodate tyres of various sizes (ranging from 8 inches to 21 inches or larger, with bespoke designs available upon request). Their primary characteristic lies in the separation of the motor from the tyre, facilitating flexible replacement of different sizes or types of tyres according to the robotic chassis's requirements. This enables adaptation to diverse terrains and load demands.

Modular design: The electric geared hub motor and tyre assembly are modular, accommodating multiple tyre sizes for simplified maintenance and upgrades. Suitable tyres may be selected according to the robot's operational requirements—whether for smooth indoor surfaces or challenging outdoor terrains.

Geared motor: Featuring an internal rotor configuration, it employs an integrated planetary gear reducer to deliver high torque output. This design is well-suited for robotic applications demanding low-speed, high-torque performance.

Independent drive capability: Supports individual wheel drive, facilitating differential steering, omnidirectional movement, or four-wheel drive modes. For instance, by adjusting the speed differential between left and right wheels, robots can effortlessly execute differential steering or even spin on the spot. When equipped with multiple hub motors, omnidirectional movement (Mecanum wheel configuration) or four-wheel drive can be achieved. Particularly suited to scenarios demanding high manoeuvrability, such as autonomous navigation robots in confined spaces or inspection robots requiring agile turning on complex terrain.

Typically compatible with mainstream robot operating systems (e.g., ROS or ROS2), seamlessly connecting to controllers via communication protocols like CAN or UART. Supports complex kinematic algorithms and high-precision path planning.

Precision Control: Capable of integrating high-precision encoders or sensors, supporting closed-loop control to deliver accurate speed and position feedback, ideal for autonomous navigation and obstacle avoidance. Encoder data is transmitted via digital interfaces (such as SPI or I2C) to the main control system. When combined with sensors like IMUs (inertial measurement units) or LiDAR, navigation accuracy is further enhanced.

Support for customisation: Parameters of the split-type hub motor can be highly customised, enabling adjustments to power, torque, speed range, and interface type according to the specific requirements of the robotic chassis. We offer multiple voltage options (commonly 24V, 36V ,or 48V) and communication protocols (such as CANopen or Modbus) to accommodate diverse control systems. Furthermore, the hub motor's physical dimensions and mounting interfaces can be customised to ensure compatibility with your robotic chassis' mechanical structure.

Robotic Chassis Applications: Extensively employed in service robots, AGVs (Automated Guided Vehicles), logistics robots, inspection robots, and similar chassis drive systems, providing stable power to support autonomous navigation, obstacle avoidance, and precise control. Should you have specific application scenarios or environmental requirements (such as particular terrain, load capacity, or speed specifications), please furnish further details. Our company can design, manufacture, and customise solutions tailored to your needs!

Indoor Smooth Surface Environments: Level concrete, epoxy flooring, tiles, or wooden floors with low surface friction coefficients, in dry and clean conditions. Suitable for warehouse logistics robots (e.g., AGVs, AMRs), service robots (delivery robots, disinfection robots, guide robots), and educational robots.

Outdoor complex terrain environments: Uneven gravel paths, grass, muddy surfaces, slopes (typically <15° gradient), potentially accompanied by moisture, dust, or minor puddles. Suitable for inspection robots (e.g., power inspection, agricultural robots), outdoor logistics robots, and off-road service robots.

Industrial production environments: Factory workshops with potential exposure to oil spills, metal shavings, or mild chemicals. Flooring typically comprises concrete or wear-resistant coatings, supporting heavy loads (100–1000kg). Suitable for factory automation robots, heavy-duty AGVs, and assembly line auxiliary robots.

Educational and R&D Environment: Laboratory or classroom settings, typically featuring level flooring, requiring frequent assembly, disassembly, and debugging, with an emphasis on modularity and ease of use. Suitable for educational robots, robotic development platforms, research experimental chassis, and similar applications.
