Behind the flexible operation of the robot, the wheel hub motor is like a precise “power heart”, containing multiple cutting-edge technologies comparable to precision watches. From material innovation to intelligent algorithms, every breakthrough in detail is reshaping the mobility of robots. Today, we will dismantle the 3 core “black technologies” of robot wheel hub motor and uncover why they have become the “golden power” in the field of robotics.
Black Technology 1: “Brushless Motor+Permanent Magnet” Combination, Dual Leap in Life and Power
Traditional brushed motor relies on carbon brushes to conduct current, and mechanical friction not only generates noise, but the wear of carbon brushes can also shorten the lifespan of the motor, usually requiring replacement after several thousand hours. The wheel hub motor adopts a brushless design, completely freeing itself from the limitations of carbon brushes. Combined with neodymium iron boron permanent magnets (with a magnetic strength 10 times that of ordinary magnets), it achieves a dual breakthrough in both lifespan and power.
Data shows that this combination can extend the service life of wheel hub motors by more than 5 times compared to traditional brushed motors, equivalent to continuous operation for 10 years without major repairs, significantly reducing the maintenance cost of robots. At the same volume, its output power is twice that of traditional motors. That’s also why a seemingly compact home cleaning robot can easily drag a stain box that weighs three times its own weight, and still has full power when cleaning heavy carpets.
Black Technology 2: “Electronic Differential Algorithm” enables robots to accurately “move”
When robot turns and avoids obstacles in complex environments, traditional power system often suffers from problems such as slipping and trajectory deviation due to poor coordination of left and right wheel speeds. The electronic differential algorithm equipped on the wheel hub motor can be called the “dynamic balance master” of robots.
When the robot needs to turn, the system can calculate the road conditions and steering angle in real time, and instantly adjust the speed difference between the left and right wheels. For example, when turning left, the left wheel decelerates by 30% while the right wheel accelerates by 20%. Through precise power distribution, the robot can turn flexibly like a feline. In the testing of a certain storage robot, after adopting this technology, the turning error was reduced from 5 centimeters to 0.5 centimeters, and even in narrow passages filled with goods, millimeter level precision positioning could be achieved.
Black Technology 3: “IP67 level packaging”, fearless of harsh environmental challenges
Water stains from household mopping, rainwater from outdoor inspections, and dust from industrial workshops are all “invisible killers” of robot motors. The wheel hub motor can reach up to IP67 waterproof and dustproof packaging technology, building a sturdy protective wall for robots.
This technology can completely isolate the motor from dust intrusion, and its performance is not affected even after soaking in water at a depth of 1 meter for 30 minutes. In the agricultural scene, the inspection robot equipped with this technology shuttles through the farmland in the rainstorm, and the motor still operates normally; In a home setting, even if a cleaning robot accidentally enters a flooded area in the bathroom, it can calmly exit and continue working. This strong environmental adaptability expands the application scenarios of robots from indoor to more complex outdoor fields.
The integration of these 3 “black technologies” has made the robot wheel hub motor not only a power output device, but also a core support for robot intelligence.
And Shenzhen Zhongling Technology Co., Ltd. has always adhered to the path of wheel hub motors, from extending service life to improving motion accuracy, to breaking through environmental limitations. Every technological upgrade of Zhongling Technology’s wheel hub motors is driving robots to evolve towards higher efficiency, reliability, and flexibility, injecting infinite possibilities into future intelligent life.
