Hub gears for your autonomous logistics and industrial service applications
Driverless transport systems in intralogistics, autonomous hospital robots, AGVs in agriculture, and self-driving cleaning robots in buildings – reliable mobility solutions are needed in more sectors than ever before.
Our modular hub gears can provide the right drive system for your mobile application. We combine the wheel, bearing, and high-performance planetary gear into one compact unit that is easy to integrate into your application.
Since every application is different, our hub gears can be tailored precisely to your requirements – either from our standard series or as a custom-engineered drive solution.
How can we get your application moving?

Highly integrated wheel hub drives – all in one compact system
In addition to hub gears, we also offer complete wheel hub drive systems. These highly integrated wheel hub drives combine the wheel, a high-precision planetary gearbox, a powerful motor, as well as a brake, encoder, and control unit, all in one comprehensive package.
Our wheel hub drives are available in two model variants that differ primarily in terms of size, load capacity, and motor power. Both versions can be adapted to your application by selecting the appropriate planetary gear ratio and choosing between Standard, Advanced, or Ultimate configurations. As with our gearboxes, we also provide fully customized wheel hub drive design tailored to your specific application.

End-to-end system solutions designed to meet a wide range of requirements
The modular, scalable wheel hub drive system is available in various configurations with uniform installation space and identical load capacities. The “Standard” version boasts a tried-and-true system with a plug-and-play setup that is easy to use in vehicles. This provides vehicle manufacturers with an application-specific system, resulting in either more compact vehicles with the same load capacity or increased usable installation space for batteries and electronics.
There are also two higher-tier versions, each of which adds more functionality than the previous version. In addition to the integrated motor controller, the “Advanced” system includes an extra motor encoder with a safety function, offering intelligent, secure control and monitoring of the systems. The “Ultimate” version has additional sensors for optimized application performance and continuous data capture to improve the entire drive cycle.

Possible applications for our hub gears and hub drives
Hub gears for AGVs in production and intralogistics
Driverless transport systems, also known as automated guided vehicles (AGVs), demand high energy efficiency, positioning accuracy, robustness, and longevity to ensure maximum uptime and precise delivery of goods. Our low-backlash, high-efficiency gearboxes and consistent gearbox-wheel separation meet these requirements.
Hub gears for medical service robots
Autonomous mobile robots transport food, medication, and many other items across floors and buildings. To ensure reliable operation in the background, the focus is on low noise emissions and a long service life. Our precisely engineered, low-maintenance planetary stages allow our hub gears to meet these demands.
Hub gears for driverless systems in agriculture
Automated guided vehicles (AGVs) are being used more and more frequently in agriculture for tasks in barns and fields. These systems must be able to handle rough terrain and withstand dirt and moisture over time. With grippy tire treads and durable seals, we prepare autonomous vehicles for Agriculture 4.0.
Hub gears for cargo bikes and small vehicles
Cargo bikes and small vehicles are increasingly handling last-mile delivery. For intelligent micromobility, low weight, high torque, and comprehensive weather resistance are the key design priorities. We meet these requirements with weight-optimized components made from high-performance plastics and continuous sealing.
AMR wheel hub drive for disinfection robots
Autonomous mobile disinfection robots consist of a self-driving platform equipped with a UV system. Ultraviolet light is used to disinfect surfaces and kill pathogens, viruses, bacteria, and other types of harmful microorganisms. Once started up by cleaning staff, the robot, which is equipped with high-precision, ultra-compact Framo Morat hub gears, moves quietly and autonomously from room to room.
