Nowadays, various types of mobile robots such as intelligent catering robot, home care robot, unmanned delivery robot, welcome robot, and building robot are rapidly entering daily life and industrial scenes, quietly improving the convenience of people's lives and the automation level of various industries. The core component that supports the smooth movement and precise operation of these robots - wheel hub motor, is also playing an increasingly critical role, and can be called the "heart of the legs" of mobile robot.

As the core actuator of robot motion, wheel hub motor is also known as the outer rotor motor. Compared with the traditional "servo+reducer" transmission scheme, it naturally has the unique advantages of more compact structure, lighter weight, and simpler and more beautiful overall appearance. From the perspective of structural principles, a hub motor is mainly composed of a stator, rotor, and supporting additional components, which is completely different from the design logic of conventional inner rotor motors: its rotor part is composed of multiple strong magnets arranged along the outer circumference of the hub, and the stator core is generally made of silicon steel sheets with insulation layer, used to place the stator winding. These windings are evenly distributed around the center of the circle, and adjacent windings are arranged at a 120 degree angle to each other. The coils on the winding are wound and arranged according to predetermined rules. When current is applied to the stator winding, a rotating magnetic field is generated. The rotating magnetic field and the rotor conductor undergo relative cutting motion. Based on the principle of electromagnetic induction, an induced electromotive force is generated inside the rotor conductor, which further generates induced current. The charged rotor conductor is subjected to electromagnetic force in the magnetic field, ultimately forming electromagnetic torque to drive the rotor to operate. The entire process is essentially a power output process that efficiently converts electrical energy into mechanical energy.

Shenzhen Zhongling Technology Co., Ltd (ZLTECH for short), which has been deeply rooted in the field of wheel hub motor for many years, has launched targeted brushless outer rotor wheel hub motor products that are suitable for various mobile scenarios, providing a complete set of motor and drive control solutions for small AGVs, service robots and other equipment. The size of this series of wheel hub motors covers the mainstream range of 4 inches to 22 inches, with optional 1024 line and 4096 line optical and magnetic encoders. The load capacity covers a wide range of needs from 50kg to 500kg, and can adapt to various scenarios from household service robots to industrial heavy-duty AGVs.

As an integrated high-tech enterprise established in 2013, ZLTECH has been focusing on the manufacturing and motion control of robot motor for more than ten years. It has gathered a large number of R&D elites who have long been deeply involved in the field of motion control, and has strong technical development capabilities in product customization. The integrated direct drive wheel hub motor has the core characteristics of high-precision closed-loop control and low-speed high torque. The related products have been widely used in automation equipment in hundreds of industries for a long time, not only selling well in various provinces and cities in China, but also exported to many countries and regions such as Southeast Asia, Europe and America.
