Compact system - high performance

Together with the Franz Morat Group, MinebeaMitsumi Technology Center Europe GmbH has developed innovative, highly integrated wheel hub drives. The complete drive combines all functional elements such as the wheel, a high-precision planetary gear, a powerful electric motor as well as brake and electronics and is particularly suitable as a traction drive for "Automated Guided Vehicles".

The modular and scalable system is characterized by its high performance in a very small space. It can be easily adapted in terms of payload, torque, interfaces, sensors and control profiles.

In addition to the high level of vertical integration in component production, motor winding and assembly, the in-depth cooperation and intelligent networking of competencies ensure short delivery times. Thanks to profound experience as a supplier in a wide range of industries, MinebeaMitsumi is a reliable development partner for your individual application.

Intelligent competence networking

Intelligent cooperation between the two development teams provides customers with the best possible results. The combination of wheel and transmission from Framo Morat and motor, brake as well as electronics from MTCE unites numerous functional elements in a very small space and enables an extraordinarily high power density.The space savings make it possible to design the vehicles smaller and to equip them with larger batteries, which among other things makes it possible to achieve longer running times. In addition, a long service life is made possible by the design separation of the gearbox and the impeller.The modular design makes wheel hub operation extremely maintenance-friendly.

There are two basic main ranges for the load capacity: Standard applications of 250 to 500 kilograms and 500 to 1000 kilograms payload per axle are possible. Both ranges use brushless DC motors. In the first range, MTCE's BLDC Motor 65 is used in combination with the NG250 hub gear. In the second range, the BLDC Motor 85 is used together with the NG5000.
