Servo Hub Motor  

Servo hub motor is an integrated system that combines motor, encoder, gearbox, wheel, and tire into one unit. It serves as both a servo motor and a walking wheel. Without a gearbox, it eliminates the noise caused by the gearbox, making the servo hub motor low in noise, easy to install, and cost-effective. It is widely used in industries that require walking, such as service robots, commercial AGVs, industrial AGVs, AMRs, etc.

DC Hub Motors History and Development Trends 

Development for motor power solution for AGV and RGV

In the history of the development of automated handling, the earliest developed RGV (Rail Guided Vehicle) adopted the walking scheme of "DC brushless motor/DC brushed motor + reducer + wheels". This makes it unable to meet the requirements of complex terrains and requires maintenance of the guide rails. In today's society with improved production levels and high automation,AGVs adopt the scheme of "servo motor + reducer + wheels + tires".But there are still some shortcomings.

The reason for requiring light customization for hub servo motors

For companies dedicated to creating highly specialized and application-specific service robots, standard wheel hub motors often cannot meet their specific needs. Therefore, customized wheel hub servo motors have become particularly important.
Customized wheel hub servo motors can be designed and manufactured according to specific needs. Here are some examples of customization directions:
1. Tire material and hardness: Different application scenarios require different tire materials and hardness.
2. Length, thickness, and fixing method of the shaft:The length and thickness of the shaft need to be precisely customized according to the size, weight, and application requirements of the robot.
3. Wiring terminals compatible with the drive: To ensure stable and efficient connection between the motor and the robot's main control board, customized wheel hub motors should consider perfect compatibility with specific drive wiring terminals.
4. Wire length and end cap: The choice of wire length directly affects the wiring layout and overall aesthetics of the robot.
Through customization, specific requirements of different industries and applications can be met, improving the performance and efficiency of robots, and bringing more convenience and benefits to people's lives and work.

DC Hub Motors and Future Market Direction

Hub motors are a technology that integrates motors directly into the wheels of vehicles, enabling the driving and braking functions of electric vehicles. Compared to traditional central drive motors, hub motors have higher efficiency, better handling performance, and lower energy consumption. In the field of robotics, hub motors have excellent mobility and precise control, providing efficient and stable motion performance for robots.
From the perspective of future market direction, in-wheel motors have several important development trends: intelligent robot assistants, intelligent warehousing and logistics, intelligent navigation and services, medical care and many other fields have broad application prospects. With the continuous innovation of technology and the expansion of application scenarios, we can expect to see more intelligent robots based on hub motors bringing more convenience and innovation to our lives and work.
