The all-inclusive powerhouse

Highly integrated wheel hub drive with Plug & Play function

We look forward to you!


All functional elements in one compact system

Framo Morat has developed a highly integrated wheel hub drive that combines all functional elements, such as the wheel, a high-precision planetary gear, a powerful electric motor and a brake and electronics, into one all-inclusive solution. This modular and scalable system boasts high performance in a compact design and lets users make adaptations to the load capacity, torque, interfaces, sensor system and control profiles.

A high level of vertical integration in the component production, motor winding and assembly helps achieve short delivery times. When providing service and consultation, Framo Morat draws upon over 100 years of experience in gear technology and drive engineering and many years of industry expertise.

Hub gearboxes – Platform and customer-specific adaptations

Besides the complete drive system, hub gearboxes from Framo Morat have proven their utility in connection with other motors, brakes & controlers, in wheel drives for driverless transport systems thanks to their compact design, which is achieved by integrating the planetary stage into the impeller. The advantageous arrangement of the bearings and the direct transmission of force into the vehicle frame enable high radial loads.

To facilitate short delivery times, the hub gearboxes are available in the NG250 and NG500 variants, each in single- and double-stage versions with polyurethan wheels. The low-maintenance design makes it easy to change the wheel. Customer-specific adaptations, such as a brush seal for outdoor applications or a toothed belt for use in high-bay warehouses, can be made upon request. Further information about the hub gears you’ll find at the Framo Morat website.
