16 Inch BLDC Hub Motor

Agricultural robot chassis are gradually becoming key to improving operational efficiency and reducing labor costs. The drive system, as a core component of the chassis, directly affects the robot's motion control and stability. It enables basic motion functions such as walking and turning through components like motors and wheels and has the ability to handle complex terrain (e.g., anti-slip, dynamic balance, etc.).

16 inch wheel hub motors are a motor technology that integrates the power system, transmission mechanism, and braking functions within the wheel itself. With IP67-rated sealing protection and corrosion-resistant structural optimization, they can operate stably in complex terrains such as muddy field ridges, loose soil, and slopes and support multiple drive modes (such as front-wheel drive, all-wheel drive) and differential steering functions.

Parameter Table

1. Compact Structure

Traditional agricultural machinery has bulky gearboxes, drive shafts, and differentials that take up a lot of space, increasing design complexity and maintenance difficulty. Electric wheel hub motors integrate the drive system directly into the wheel, eliminating the need for traditional drive shafts, gearboxes, and other complex mechanical components, and achieving a highly integrated design.

(1) By eliminating traditional transmission components, chassis space is freed up (accommodating larger-capacity batteries, sensors, or expanded cargo areas), while this lightweight design effectively reduces overall vehicle load and improves chassis operational efficiency.

(2) Four-wheel independent drive supports differential control, on-the-spot turning, and multi-degree-of-freedom movement modes, enabling the robot chassis to move freely in narrow spaces or complex terrains.

(3) A simplified mechanical structure reduces failure points by over 70%, combined with a modular gearbox design (supporting quick disassembly and replacement), maintenance efficiency improves by 60%, and overall maintenance costs are reduced by over 40% (based on general data).

2. High Energy Conversion Efficiency

16 inch hub motors drive the wheels directly, reducing energy loss during mechanical transmission (such as friction and idling loss in components such as gearboxes and drive shafts). This “point-to-point” power transmission method means higher energy conversion efficiency, which can effectively reduce energy consumption and extend the battery life of agricultural robot chassis, especially for robot chassis that operate outdoors for long periods of time.

3. Precise Control 

The 16-inch geared hub motor can achieve millimeter-level dynamic control of equipment movement through four-wheel independent drive and high-precision sensor fusion.  

(1) Omnidirectional Free Movement: Each wheel can independently adjust speed and torque (e.g., differential control, reverse output), supporting complex maneuvers such as on-the-spot turning, diagonal movement, and crab mode, adapting to narrow spaces or complex terrain.

(2) Precise Path Tracking: The millisecond-level electronic control system, combined with gyroscope and encoder feedback, dynamically adjusts wheel output (e.g., automatic torque compensation when load changes), achieving positioning accuracy of ±1mm, ensuring precision in tasks such as seeding, fertilizing, and spraying.

4. Powerful Off-Road Capability

The 16-inch wheel rim size, combined with off-road tires designed specifically for farmland, provides agricultural robots with excellent traction and passability. At the same time, high-quality wheel rim motors usually have high torque output characteristics, ensuring that robots can run stably in wet, muddy, soft, or sloped farmland and easily cope with complex terrain.

(1) Ultra-high torque for complex terrain: Capable of instantaneous high torque output, easily climbing slopes steeper than 30 degrees and traversing low-friction surfaces such as mud, gravel, sand, and ice;

(2) All-terrain adaptability: Modular design supports quick replacement of off-road tires (such as puncture-resistant tracks or deep-tread tires), combined with optimized suspension systems, to adapt to extreme environments like mountains, deserts, and construction sites;

(3) High protection and durability: IP67-rated sealed structure resists dust and water immersion (e.g., water depth up to 1 meter), ensuring the electric wheel hub motor can operate at high intensity for extended periods;

(4) Enhanced dynamic stability: Combining IMU sensors and AI algorithms, it adjusts wheel speed and vehicle posture in real-time (e.g., automatically balancing the center of gravity when driving on side slopes), improving operational safety in complex terrain.

Key factors to consider when selecting a 16-inch hub motor

When selecting the appropriate 16-inch hub motor for your agricultural robot chassis, please pay close attention to the following points:  

Rated power and torque: Ensure the motor provides sufficient power to handle complex field conditions and expected loads.

Protection rating: A high IP rating (such as IP65 or higher) indicates stronger dust and water resistance, suitable for harsh farm environments.

Voltage and current: Compatible with your battery system and controller.

Integrated encoder/Hall sensor: Provides precise position and speed feedback for closed-loop control.

Braking method: Whether regenerative braking is supported and whether additional mechanical braking is required.
