In the current era of the comprehensive outbreak of the intelligent mobile robot industry, the walking power unit is no longer just a simple driving component, but the core lifeline that determines equipment positioning accuracy, traffic stability, and overall durability. Shenzhen Zhongling Technology Co, Ltd. (ZLTECH for short), which has been deeply involved in the field of motion control for more than ten years, uses self-developed external rotor wheel hub motor as its core, breaking the bulky solution of traditional motor and gearbox. With highly integrated, high torque, and high-precision control hardcore products, it has become the preferred power solution for AGV logistics vehicle, inspection robot, commercial service robot, and medical care equipment, creating a strong and reliable "smart foot" for intelligent equipment.

Structural innovation and direct drive integration reshape the power form, which is the most iconic breakthrough of ZLTECH wheel hub motor. Different from the traditional split design of the drive system, ZLTECH integrates permanent magnet motor, high-precision encoder, drive bases, wheel hub, and tire, abandoning the transmission shaft, differential, and multi-stage gear reduction structure, and achieving direct drive of the wheels by the motor. The exclusive magnetic field optimization design of the outer rotor increases the torque output by 30% compared to traditional inner rotor motors under the same power. It still runs smoothly at a low speed of 0.1rpm, with a peak torque of up to 20N · m, making it easy to complete heavy-duty climbing and obstacle crossing; The integrated layout reduces the overall volume of the machine by 50%, and the weight is reduced by more than 30% compared to traditional solutions. It is suitable for the ultra-thin body of cleaning robot and narrow channel shuttle needs of food delivery robot, and greatly simplifies the equipment assembly process, shortening the R&D and assembly cycle of the whole machine. The tire modular and detachable design allows for individual replacement after wear and tear, significantly reducing long-term operation and maintenance cost.

High precision closed-loop control, millimeter level positioning ensures the landing of intelligent operation, targeting the core pain points of autonomous walking of robot. ZLTECH's entire range of wheel hub motor come standard with multi specification encoder, which can be flexibly equipped with AB two-phase, ABZ three-phase, and UVW magnetic pole three-phase encoding scheme. It can eliminate accumulated errors during travel by relying on ABZ zero position pulses, and can replace external Hall components with UVW magnetic pole signals to achieve stable starting and vibration free commutation of brushless motors. Paired with our self-developed ZLAC series servo drive, it supports CANopen and RS485 multi bus communication, with controllable speed, torque, and position triple loops. The positioning error is controlled within ± 0.1mm, and the hotel food delivery robot can accurately dock within ± 2cm of the dining table. The material transfer accuracy of the warehouse AGV is as high as 99.9%. The power park inspection robot can also maintain stable trajectory on slopes and uneven roads, truly achieving complex actions such as autonomous navigation, precise start stop, stationary turning, and lateral movement.

Strict quality control, durable and adaptable to all scenarios, covering diversified needs of hundreds of industries. From 24V low-voltage low-power 6.5-inch wheels to 48V high-power 15 inch heavy-duty wheels, ZLTECH wheel hub motor covers a power range of 100W to 800W, with load spans ranging from tens of kilograms to 300 kilograms. The waterproof and dustproof structure is suitable for complex working conditions such as indoor enclosed spaces, outdoor factory areas, humid medical environments, and dusty industrial workshops. In the field of commercial service, food delivery, disinfection and sterilization and cleaning robot relies on low-noise direct drive structure to operate quietly in office buildings and shopping malls; In the special field, the drug delivery robot in tertiary hospitals operate 24 hours a day without interruption, ensuring the safety of consumables with zero bumps throughout the process. The security inspection robot is not afraid of sun and rain, and can stably complete all-weather outdoor duty operations.

Over ten years of technological accumulation, one-stop service empowers partners for long-term development. As a high-tech enterprise integrating research and development, production, customization, and after-sales service, ZLTECH has established a professional motion control research and development team, mastering the core technologies of motor magnetic field design, servo algorithms, and coding matching throughout the entire chain, and supporting OEM personalized customization of size, voltage, torque, and communication protocols. Each wheel hub motor undergoes multiple tests including high and low temperature aging, continuous load operation, and simulated bumpy road conditions, and undergoes strict quality inspection upon leaving the factory; Equipped with complete sets of drivers and power chassis output, the technical team provides debugging guidance throughout the process. Whether it is a start-up equipment manufacturer or a large-scale intelligent manufacturing enterprise, they can obtain highly adaptable and cost-effective power solutions.

In the era of intelligence, the walking ability of mobile devices determines the upper limit of intelligence. ZLTECH's wheel hub motor breaks through space limitations with integrated structures, conquers complex road conditions with high torque performance, and achieves intelligent autonomous walking with high-precision control. It’s are only the power heart in the wheels, but also an important cornerstone for the intelligent upgrading of the robotics industry. In the future, ZLTECH will continue to deepen the integration of motors and AI algorithms, create integrated intelligent wheel hub units for perception, decision-making, and execution, and drive the mobile robot industry towards a lighter, more accurate, and more reliable direction through technological innovation.
