In the field of unmanned robotic delivery, the efficiency and stability of the power system directly determine the quality of delivery task completion. Shenzhen Zhongling Technology Co., Ltd., with its independently developed external rotor hub motor, boasts characteristics such as low speed, high torque, high power density, and precise control, making it a core power source for the efficient operation of unmanned delivery equipment. Its power range covers 100-800W, and its speed range is 1-1000r/min, with stepless speed variation, perfectly meeting the stringent power system requirements of unmanned delivery scenarios.

Low-speed direct drive: Simplifies structure and improves efficiency

Zhongling Technology's external rotor hub motor adopts a "motor direct drive wheel" design, which can directly drive the wheel without the need for a traditional reduction gear. This direct drive hub motor integrates the drive motor, coupling, reduction mechanism, drive wheel and other transmission structures, reducing the number of drive mechanism components, reducing transmission efficiency loss, reducing wear of the moving mechanism, lowering costs, and improving the system stability and economic benefits of the robot.

High torque output: capable of handling complex road conditions

The external rotor structure gives the motor an inherent torque advantage. Zhongling Technology, through deep optimization of the magnetic field layout, has successfully achieved a precise proportional relationship between torque output and the square of the rotor diameter (D²). Under the same power conditions, its torque output is significantly increased by 30% compared to traditional internal rotor motors. Taking an 800W motor as an example, at a speed of 100 r/min, it can stably output a continuous torque of up to 20 N·m. This characteristic allows it to handle complex scenarios such as obstacle crossing with ease.

Precise control: enabling flexible movement

The hub motors are equipped with high-precision encoders with a resolution of 4096 lines, providing real-time feedback of position and speed information for millimeter-level positioning accuracy. Combined with vector control algorithms, the rotational speed of each wheel can be independently controlled, supporting flexible movements such as stationary rotation and lateral movement. In narrow office building corridors, delivery robots equipped with Zhongling motors can accurately avoid obstacles, improving delivery efficiency. Furthermore, the motor's response time is only tens of milliseconds, and its ability to quickly adjust posture ensures dynamic obstacle avoidance.

Highly adaptable: meets diverse needs

To address the diverse needs of unmanned delivery scenarios, Zhongling Technology has launched a full-size in-wheel motor product line ranging from 4 inches to 16 inches. Among them, motors in the 100-800W power range can be adapted to delivery equipment with different load capacities.

Lightweight: The 100W motor is suitable for small indoor delivery robots and is compact in size;

General purpose: The 400W motor balances power and energy consumption, making it the mainstream choice for community delivery robots;

Heavy-duty type: The 800W motor can carry 300kg of goods, meeting the needs of industrial parks, logistics centers and other scenarios.

Shenzhen Zhongling Technology Co., Ltd.'s external rotor hub motors, with low-speed, high-torque as their core, have redefined the power standards in the unmanned delivery field through structural innovation and intelligent control. From communities to industrial parks, from indoors to outdoors, Zhongling motors are driving unmanned delivery technology towards greater intelligence and reliability with their efficient, stable, and flexible performance. In the future, with the deep integration of technologies such as the Internet of Things and AI, Zhongling Technology will continue to push the boundaries of power density and control precision, injecting even stronger momentum into the global unmanned delivery industry.
