Shenzhen ZhongLing Technology Co., Ltd.

Today, with the rapid popularization of intelligent robot, AGV logistics vehicle, and unmanned inspection vehicle, the working conditions faced by mobile chassis are becoming unprecedentedly complex. Heavy load climbing, high-frequency start stop, rain, snow, mud, and even condensation caused by temperature differences between day and night - the failure of any link can lead to the paralysis of the entire system. As a technology driven enterprise that has been deeply involved in the field of hub motor power for many years, Shenzhen Zhongling Technology Co., Ltd. (ZLTECH for short) has always adhered to a difficult but correct path: only by truly mastering electronic control and structure can high reliability wheel hub power be defined from the root.

Electronic control is not only a driver, but also the brain implanted in the motor

Many hub motor solutions are accustomed to the patchwork thinking of "motor to motor, driver to driver", which precisely ignores the reliability dividend brought by the deep integration of electronic control and the body. At ZLTECH, hub motor power has been designed as an integrated system since its inception.

We have developed an embedded intelligent drive unit specifically for hub motor, based on our self-developed FOC vector control algorithm, which compresses the control cycles of the current loop, speed loop, and position loop to the microsecond level. This not only allows the motor to output stable high torque at extremely low speeds, completely eliminating shaking and abnormal noise, but also gives each motor the ability to "self perceive". Real time monitoring of current, temperature, and bus voltage, transparent transmission through CANopen or RS485 bus. Once there is a trend of locked rotor, overheating, or overcurrent, the system will actively provide derating protection or warning. It is equivalent to equipping each wheel with an tireless driver to constantly safeguard driving safety.

It is precisely this repeated polishing of the underlying code and protection strategies of the electronic control system that enables ZLTECH Hub Motor Power to remain calm and composed amidst the intense impact of the robot passing through obstacles and the high current surge during full load start-up. What we deliver is not only the correct waveform of the current, but also the unwavering reliability under various extreme working conditions.

Structure, using the most solid skeleton to support long termism

If electronic control is the soul of hub motor power, then the motor structure is the tough skeleton. Hub motors naturally operate under suspension and need to directly withstand radial external forces and axial impacts. Any compromise in structural design will be exposed in the face of time.

The engineering team of ZLTECH used electromagnetic field simulation and structural finite element analysis to perform hundreds or thousands of optimization iterations on the internal pole slot matching and magnetic steel arrangement of the motor. High grade low loss silicon steel, high-temperature resistant neodymium iron boron permanent magnets, and precision matched military grade bearings reduce the cogging torque and torque ripple of the motor to extremely low levels, suppressing vibration and noise from the source. At the same time as the power density is significantly increased, the mechanical fatigue life is doubled.

We will not compromise on the water dust and condensation that hub motor power is most afraid of. ZLTECH hub motors generally achieve a protection level of IP65 or above. A combination of multiple labyrinth seals and polymer breathable valves is used at the shaft end, which can effectively block external water and dust intrusion, balance the air pressure inside and outside the cavity, and prevent internal condensation caused by breathing effects. From the severe temperature difference caused by frequent entry and exit of the cold storage to the continuous rain and mud splashing outdoors, our products have proven their all-weather combat capability on numerous customer sites. In addition, the outgoing part adopts high flexible shielded cables and reinforced stress relief design, which solves the common pain point of "wire breakage" in the industry in one fell swoop.

Through countless trials and tribulations, engrave reliability into the product's DNA

The word 'thoroughly penetrated' originates from the rigorous verification conducted day after day in the laboratory. Before each ZLTECH hub motor power is launched, it must go through layers of hard tests: continuous over 1000 hours of load aging, tens of thousands of extreme stall impacts, high and low temperature cycles from -30 ℃ to 70 ℃, salt spray corrosion, and rigorous EMC testing.

Due to this almost obsessive pursuit of reliability, ZLTECH hub motor power solutions have been widely applied in high-end fields such as outdoor distribution robots, park shuttle buses, heavy-duty AGVs, and special security inspections that have zero tolerance for faults. There has been feedback from integrators that on 2-ton heavy-duty backpack AGVs, ZLTECH hub motors have achieved continuous maintenance free and stable operation for over 8000 hours, which has strengthened our commitment to a long-term approach.

Delivering power is also a commitment to delivering wind and rain

For ZLTECH, manufacturing hub motors is not a simple assembly of components, but a reliable delivery after the deep integration of multiple disciplines such as electrical control, magnetic circuit, transmission, and protection. We provide a full chain service from standard products to customized deep parameters, analyzing actual working conditions with customers, matching the most suitable wheel hub power module, and even jointly developing proprietary functions.

In the future mobile world, roads will become increasingly complex and tasks will become heavier, and hub motor power must be the least worrying existence. Choosing ZLTECH means choosing the long-term reliability of hub motor power.
