Specially designed Motion-Connect technology and measuring systems for your motion control applications. Facilitates project planning and commissioning.

Servo geared motors combine the precision and dynamics of servomotors with gearbox technology. They enable compact machine designs, precise motion, high efficiency and flexible configuration, making them the ideal choice for demanding motion control applications across many industries.

Servomotors with planetary gearboxes are highly dynamic, compact and efficient with optimized inertia matching. Wide gearbox ratios enable precise motion, high cycle rates and efficient integration into a range of applications.

Servomotors with standard gearboxes have a compact, direct-mounting design, high efficiency and low torsional backlash, and low running noise due to helical teeth. They’re also maintenance-free and lubricated for life.

In addition to a pre-mounted solution, you can also mount gearboxes to our servomotors and main motors through a KS adapter. Our motors equipped with standard gearboxes round out our portfolio.

Available with angled planetary gearboxes NLCW / NRKW / NRBW

Available with precision gearboxes SP+ and TP+

Available with precision gearboxes SP+

Available as servo helical, servo parallel shaft, servo bevel and servo helical worm geared motors

Fully assembled solutions and flexible motor gearbox combinations support fast commissioning as well as customized drive configurations.

Different gearbox variants and ratios allow optimal matching of motor inertia to the load, improving control quality, efficiency and machine throughput.

The thermal dimensioning is just as simple as for a servo motor thanks to the digital twin of the geared motors in the TIA selection tool.

The direct mounting creates an extremely compact design. There is no coupling cage between the motor and gearbox.

The motors combine high efficiency with low torsional backlash and low running noise thanks to helical teeth. Maintenance‑free design with lifetime lubrication reduces service effort and increases availability.

Servo geared motors are used in motion control applications requiring precise positioning, high dynamics and compact drive solutions, such as packaging, handling and automation systems.

Planetary gearboxes offer higher precision, lower backlash and better dynamics, while standard gearboxes provide robust torque transmission for a wider range of industrial applications.

Planetary geared motors are specified and delivered completely as a unit. All outstanding performance data are matched to the motor-gearbox combination.
