12 Inch Geared Hub Motor

The 12-inch BLDC hub motor is favored by most robot chassis customers due to its integrated design and high performance. It eliminates the need for traditional mechanical transmission devices, external gearboxes, or complex belt/chain transmission systems, reducing overall mechanical complexity, system weight, and potential failure points. It can be used in various environments, from rugged outdoor terrain to indoor precision tasks, making it ideal for robot chassis applications in industries such as agriculture, manufacturing, transportation, warehousing, inspection, and firefighting.

High Torque Output

The 12 inch hub motorr's direct drive hub characteristics and efficient transmission design enable instant high torque output (up to 6000 N.m) when driving on uneven farmland, urban landscapes, or warehouse floors, providing powerful power support for equipment in complex working conditions.

1. Instantaneous force burst: Gear-less traction transmission, with air pressure directly acting on the wheels, meets the strong traction requirements for heavy loads (transporting goods over 500 kg), steep slopes (climbing 30° inclines), and low cargo lifting (mud, ice, and snow);

2. Dynamic load adaptation: Through coordination between the encoder and controller (e.g., CAN bus protocol), real-time adjustment of data output (±1% accuracy) is achieved. During load changes (e.g., when the robot crosses obstacles), power is automatically compensated to prevent stalling or loss of control;

3. Full scenario coverage: Ensures continuous and stable operation under extreme conditions such as frequent start-stop cycles (e.g., logistics robots exceeding 5,000 start-stop cycles per day) and high impact (e.g., impact forces exceeding 10 kn in off-road environments).

Handling More Complex Road Conditions

1. Dynamic traction control: Single-wheel instantaneous high-limit air pressure (up to 6,000 Nm) combined with electronic differential technology enables climbing slopes steeper than 30°, navigating muddy, gravel, sandy, and icy surfaces, with off-road capability far surpassing traditional drive systems;

2. Dynamic response in all scenarios: Four-wheel independent control supports complex maneuvers such as on-the-spot turning and crab mode (e.g., AGV robot navigation through a 10cm-wide narrow path). Combined with IMU sensors and AI algorithms, it dynamically adjusts vehicle posture (side slope turning with automatic center of gravity balancing) to ensure maneuvering stability under extreme turning conditions;

High-Efficiency Operation

For robot chassis, the efficiency advantage of high torque 12 inch hub motors lies in their ability to efficiently deliver high torque, which is crucial for carrying loads, climbing slopes, and overcoming obstacles. Although gearboxes cause some mechanical loss, their efficiency advantage can be maximized by selecting high-quality products, matching loads appropriately, and implementing proper control and maintenance, thereby providing robot chassis with good power and long endurance.

Precise Control Operations

The 12inch geared hub motor provides precise control capabilities for the robot chassis through its integrated encoder and support for closed-loop control, enabling highly accurate positioning, smooth movement, and rapid response to commands.

1. Speed Adjustment: The robot chassis can achieve very small speed changes, ranging from extremely slow crawling to rapid movement. This precise speed adjustment is highly advantageous for tasks requiring careful operation, such as handling fragile items or maneuvering in confined spaces.

2. Instantaneous Response: Due to the presence of closed-loop control, the motor can quickly respond to control commands, whether accelerating, decelerating, or changing direction. This rapid and accurate response capability enhances the robot's agility and operability.  

3. Precise Parking: The robot can precisely move to the target position and stop with minimal error. For example, a delivery robot can accurately stop at a charging station or item drop-off point.

4. Smooth Movement: Thanks to precise feedback and control, gear hub motors can achieve very smooth speed control, minimizing speed fluctuations and vibrations even at low speeds or during load changes. This is critical for robots requiring smooth movement, such as medical robots or service robots.

Common Robot Chassis Applications

Autonomous mobile robots (AMRs) and automated guided vehicles (AGVs): In warehouses, factories, and hospitals, mobile robot platforms use gear hub motors to transport materials, deliver supplies, and automate logistics. They can handle heavy loads, navigate complex environments, and operate continuously.

Service Robots: These include, but are not limited to, cleaning robots, delivery robots (e.g., for transporting food or packages), security robots, and even some medical robots. They can operate effectively and safely in human-centric environments and typically require continuous work cycles.

Outdoor and Inspection Robots: For robots designed to traverse challenging outdoor terrain, such as agricultural robots, infrastructure inspection robots, or search-and-rescue robots, they are often used to navigate rugged terrain, slopes, and unpredictable obstacles. Our wheel hub motors feature a robust and sealed design, providing reliable protection against harsh weather conditions.

Education and research platforms: From university research projects to DIY enthusiasts, gear hub motors offer efficient drive solutions for building mobile robot platforms. They enable developers to focus on higher-level algorithms and sensor integration without the need to design complex mechanical transmission systems.

To provide 12 inch hub motors that meet your requirements, please consider the following key factors:

Load requirements: Match the motor's torque and speed capabilities to the robot's expected weight, speed, and acceleration.

Wheel size: Wheel diameter directly affects the required motor torque and final ground speed.

Environmental factors: Dust and water resistance IP ratings (protection ratings) are critical for outdoor or industrial environments.

Power supply: The motor's voltage and current must be compatible with the robot's battery system.

Control system compatibility: Ensure that the motor's encoder and driver seamlessly integrate with the robot's main controller (e.g., CAN bus, PWM, serial communication, etc.).
